4-D NEUROIMAGING    NOTES TO CONSOLIDATED FINANCIAL STATEMENTS    (unaudited)

NOTE
1. BUSINESS AND BASIS OF PRESENTATION

4-D
Neuroimaging, or 4-D, (formerly Biomagnetic Technologies, Inc.), a California corporation originally founded in 1970 to produce equipment for physics
labs, currently develops, manufactures, markets and sells medical instrumentation that allows physicians to monitor how the body is functioning, and provides an important tool to neuroscientists
helping them to unravel how the brain functions. The basic technology is referred to as either Magnetic Source Imaging, or MSI, or when specific to the brain Magnetoencephalography, or MEG. MEG/MSI
systems locate and measure magnetic fields generated by the human body, and assist in the noninvasive diagnosis of a potentially broad range of medical disorders. These measurements provide useful
information about the normal and abnormal functioning of the brain, heart, spine and other organs. Currently, the Company is focusing its efforts on MEG/MSI applications for the brain.

On
December 22, 1999, 4-D Neuroimaging acquired all of the issued and outstanding capital stock ("Shares") of Neuromag Oy pursuant to the terms of a Share Purchase
Agreement, by and between Marconi Medical Systems, Inc. ("Marconi") and 4-D (the "Share Purchase Agreement"). Similar to 4-D, Neuromag Oy is engaged in the research,
development, manufacturing and sales of MSI systems. The acquisition of Neuromag Oy has been accounted for under the purchase method of accounting. The Company paid $10 million in cash and
agreed to pay Marconi an interest-free minimum royalty obligation of $312,500 per year for eight years totaling $2.5 million and a maximum of $5 million in royalties and
additional consideration dependent upon the occurrence of certain future events. The minimum royalty obligation was recorded at acquisition at a net present value of $1.7 million using an
imputed interest rate of approximately 10 percent. The fair value of net assets acquired was approximately $900,000. The purchase price in excess of the fair value of net assets acquired was
recorded as goodwill totaling approximately $10.8 million and was amortized through fiscal year ended September 30, 2001. Thereafter, as required by SFAS No. 142, goodwill and
certain intangibles will no longer be amortized, but instead tested for impairment at least annually. The Company has early adopted SFAS No. 142 in fiscal 2002. The Company performed an
impairment analysis in consultation
with an independent valuation firm in March 2002. Based on the analysis, the Company formed the opinion that 4-D has no goodwill impairment as of October 1, 2001 and for the
six months ended March 31, 2002. The Company continues to review the impact of this statement and will make any necessary adjustments, as appropriate.

The
unaudited consolidated condensed financial statements of 4-D Neuroimaging and its subsidiaries, Neuromag Oy, a wholly owned Finnish entity, and Biomagnetic Technologies,
GmbH, an inactive wholly owned German entity, (together, the "Company", "we", "our", or "4-D") have been prepared in accordance with the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States
have been condensed or omitted pursuant to such rules and regulations. The Company suggests that these financial statements be read in conjunction with the financial statements and notes thereto
included in the Company's annual report on Form 10-K for the fiscal year ended September 30, 2001.

In
the opinion of the Company, the accompanying unaudited consolidated condensed financial statements contain all adjustments, consisting only of normal recurring entries, necessary to
present fairly its financial position at March 31, 2002 and the results of its operations and its cash flows for the periods presented.

6

---

The
preparation of financial statements, in conformity with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates. Results for the interim periods presented in this report are not necessarily indicative of results which may be reported
for any other interim period or for the entire fiscal year.

NOTE
2. BASIC AND DILUTED NET LOSS PER SHARE

Shares
used in computing basic and diluted net loss per share include the weighted average number of common shares outstanding as of March 31, 2002. Potentially dilutive
securities, including stock options, are antidilutive and are excluded from the computation of diluted net loss per share.

NOTE
3. BUSINESS RISKS AND UNCERTAINTIES

The
Company continues to experience serious liquidity issues and incurred net losses of $4,501,000, $8,127,000 and $7,464,000 in fiscal 2001, 2000 and 1999, respectively. The Company had
negative cash flows from operations of $4,153,000, $5,217,000 and $8,602,000 in fiscal 2001, 2000 and 1999, respectively. For the quarter ended March 31, 2002 the Company incurred a net loss of
$826,000 and had negative cash flow from operations of $952,000. At March 31, 2002 the Company had an accumulated deficit of $112,953,000, shareholder equity of $3,497,000 and a working capital
deficiency of $3,592,000. On March 31, 2002 the Company had restricted cash of $202,000. Neuromag Oy has bank guarantees related to a system for approximately $140,000 and other miscellaneous
guarantees of approximately $44,000.

The
accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed above and as shown in the accompanying
consolidated financial statements, the Company has operating and liquidity concerns that raise substantial doubt about its ability to continue as a going concern. There can be no assurance that the
Company will be able to successfully improve its operating results and further restructure its indebtedness or that its liquidity and capital resources will be sufficient to maintain normal operation.
The financial statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result
should the Company be unable to continue as a going concern.

Based
on the Company's current expectation of anticipated cash receipts related to firm orders received and anticipated bookings of up to two additional MEG/MSI systems, it expects to
have sufficient cash to continue operations through July 2002 without taking into account cash requirements for maturities of its notes payable. Historically, the Company has raised additional
capital through its majority shareholders and related parties to fund continuing operations. The Company is working with these shareholders and related parties to renegotiate, reduce or repay its debt
obligations and to provide additional funding for operations. There can be no assurance that these sources of capital and funds will be available, or that its existing debt can be renegotiated on
terms acceptable to the Company, if at all.

Realization
of the Company's operating plans is dependent upon its ability to successfully close a number of MEG/MSI system sales in a highly competitive market for the limited number of
systems being purchased worldwide. There can be no assurance that sufficient sales of MEG/MSI systems will be achieved in order to realize the current operating plans. Historically, there has been
ongoing price competition from the Company's competitors for the currently limited number of whole head systems being purchased worldwide. This competition may affect potential future profitability of
the MEG/MSI systems, the extent of which is not presently determinable. Competitors may develop new or different products using technology or imaging modalities that may provide or be perceived as
providing greater

7

---

value than the Company's products. Any such development could have a material adverse effect on its financial position, results of operations and cash flows.

The
Company's long-term commercial success in the U.S. is dependent upon obtaining routine approval of reimbursement for clinical MEG/MSI procedures by third-party payors.
The Centers for Medicare
and Medicaid Services, or CMS, formerly known as the Health Care Financing Administration, or HCFA, which is responsible for the administration of Medicare, and the American Medical Association, or
AMA, that administers the use of Current Procedural Terminology, or CPT, codes by most third-party payors, follow similar guidelines for determining whether a specific procedure or health care
technology is "reasonable" and "necessary", and therefore reimbursable under Medicare or private insurance coverage. These guidelines generally include consideration of whether (i) the
procedure or technology is more or less costly than an alternative already covered by insurance, (ii) the added benefit of the procedure or technology is significant enough to justify the
expense, and (iii) the procedure or technology provides significant medical benefits not otherwise available from other procedures or technologies.

The
Company has worked for several years with its customers and the American Academy of Neurology, or AAN, to obtain CPT codes for MEG. These efforts came to a successful fruition in
February 2001 when the AMA announced that it would assign the first three CPT specific codes for the use of MEG. The codes for MEG were published in the Federal Register on November 1,
2001.

In
the publication of the CPT codes on November 1, 2001, the reimbursement level to be paid for the use of the equipment, also known as the Technical Component fee, was designated
to be carrier based. This means that each insurance carrier will independently assign a payment level. The Company will work with each of its customers and prospects to establish appropriate
reimbursement levels with the carriers used by their patients. This has been the method of reimbursement that the Company's customers have been using for up to eight years and, with the Company's
help, have been able to obtain satisfactory levels of reimbursement. The Company will continue to work with its customers, with the added advantage of having the CPT code available.

In
December 2001, the CMS published the Ambulatory Patient Cost, or APC, codes. APC codes are cost-based codes that set the technical fee that Medicare will pay for
ambulatory patients being treated within the hospital. MEG was assigned to the "New Technology" section of the codes. Within this section are reimbursement levels from $0 to $6,000 per procedure. MEG
was assigned to what the Company believes is an inappropriately low level of approximately $150 per procedure. MEG users and the AAN are in the process of appealing this assignment. The APC process is
new, thus there can be no assurance as to when or if the CMS will make an appropriate assignment, however, there is considerable support among the AAN and MEG users to effect a change to the proper
cost-based level.

The
CPT codes became available for use starting in January 2002. They provide the basis for the first routine reimbursement for MEG. The first code is used primarily for the
evaluation of candidates for epilepsy surgery, while the other two codes are used for pre-surgical functional mapping procedures. The Company's current sales strategies in the U.S. focus
on the development of commercially viable sales to clinical users. It is always difficult to predict the adoption rate of a new modality, but with the assignment of CPT codes the Company believes that
it has a new and powerful sales approach.

In
April 2001, the Company retired approximately $10.5 million of its debt, raised $2 million of working capital and restructured approximately $3 million of
its remaining debt owed to AIG Private Bank Ltd.
See Note 4 of this report for additional information regarding the debt restructuring and the related private placement.

The
Corporation's officers are authorized on behalf of the Company to offer and issue up to 15,000,000 shares of the Company's common stock at a price not less than $0.13 per share. In
the three

8

---

month period ended March 31, 2002, 7,692,308 shares were issued to an outside investor in a private placement transaction in accordance with Section 4(2) of the Securities Act of 1933,
as amended, in exchange for cash in the aggregate sum of $1,000,000.

The
report of the Company's independent public accountants on the Company's financial statements included in its Form 10-K for the year ended September 30, 2001
contained a modification related to its ability to continue as a going concern.

NOTE
4. DEBT OBLIGATIONS

To
acquire the shares of Neuromag Oy in 1999, the Company obtained a loan from AIG Private Bank Ltd., or AIG, totaling $11 million that is secured by the entire share
capital of Neuromag Oy and is guaranteed by an entity affiliated with Martin Egli, a member of the Company's board of directors. Mr. Egli also serves on AIG's board of directors. The
$11 million loan was restructured in July 2000, which extended the original maturity date from June 30, 2000 to December 29, 2000 and the principal amount was increased to
$11.4 million. On December 29, 2000, the Company did not make payment at maturity of the loan. Effective February 15, 2001, the Company and AIG reached an agreement in principle,
extending the maturity date to July 20, 2001, increasing the loan principal to approximately $12 million (capitalizing accrued interest of approximately $550,000 into the loan principal)
and obtaining additional guarantees of indebtedness from another bank.

On
April 26, 2001 the Company reached an agreement with AIG in which $8.951 million of the principal and accrued interest of the loan was converted into shares of the
Company's common stock as part of a private placement. The remainder, approximately $3 million of the loan, was restructured. As restructured, the loan in the principal amount of
$3.357 million from AIG matures in July 2002 and the interest rate was set at 6.8% per annum until April 26, 2002, at which time the interest rate was reduced to 4.4% per annum
for the remainder of the loan term. As amended, the AIG loan is secured by a pledge and assignment by Scaloway Co. Ltd., or Scaloway, a guarantee in the amount of $2.2 million by Bank
Julius Baer & Co. AG in Zurich, Switzerland, and all of the issued and outstanding shares of Neuromag Oy, 4-D's wholly-owned subsidiary located in Helsinki, Finland. If
4-D defaults under the AIG loan, then AIG has the right to exercise its security interest and take ownership of Neuromag Oy. In connection with the April 2001 private placement
transaction, Scaloway agreed to convert certain assets pledged and assigned by Scaloway into an indirect ownership of all 42,623,810 shares of 4-D's common stock issued to AIG, Scaloway
has sole voting and dispositive power over these shares. Martin Velasco Gomez, a member of 4-D's board of directors, is the beneficial owner of Scaloway.

In
June 2000, the Company obtained unsecured loans totaling approximately $835,000 from BDN and used approximately $485,000 of the proceeds to pay interest due under the AIG loan
at June 30, 2000 in conjunction with extending the maturity of the loan from AIG to December 29, 2000. BDN is a Spanish company owned by three members of the Company's board of
directors, Martin Egli, Enrique Maso and Martin Velasco Gomez. The BDN loans were originally due on September 30, 2000. During October 2000, the Company repaid approximately $123,000 of
principal and $27,000 of interest for these loans and negotiated an extension of the maturities of the BDN loans until March 31, 2001. As part of a reduction in its capital BDN reassigned its
rights under the BDN loans to Amaldos, S.A., MATRUST, S.L., International Sequoia Investments Limited and Swisspartners Investment Network Ltd. Dr. Maso is a majority shareholder in
MATRUST, S.L. Mr. Velasco Gomez is a major investor in International Sequoia Investments Limited, or Sequoia. Mr. Egli is a member of the board of directors and a managing partner of
Swisspartners Investment Network Ltd., or Swisspartners. An additional $18,500 of interest and $1,500 of principal was repaid before the majority of these loans were reassigned to the
principals of BDN on April 15, 2001, excluding $30,000. Subsequently these reassigned loans were converted to equity on April 26, 2001 as part of a private placement, and the remaining
$30,000 of principal was repaid to BDN at that time.

In
September 2000, the Company obtained an unsecured loan from Swisspartners in the principal amount of $450,000. In March 2001 Swisspartners loaned an additional $400,000
to the Company under the same loan arrangement. On April 26, 2001, Swisspartners converted the entire principal and all accrued interest of the loan, in the total amount of $872,867, to equity
as part of a private placement.

Prior
to its acquisition by 4-D, Neuromag Oy borrowed a total of 3,140,000 in Finnish Markka, or FIM, which equaled approximately $460,000 USD at March 31, 2002, from
TEKES at the Finnish state base interest rate minus 1%, subject to a minimum rate of 3%. The future repayment date for principal and related accrued interest outstanding under this loan is dependent
upon Neuromag Oy generating sufficient distributable equity based upon the statutory financial accounts prepared in accordance with Finnish generally accepted accounting principles, in the future.

In
January 2002, 4-D obtained two unsecured loans from the Company's board of directors, each in the amount of $125,000, with an interest rate of 8% per annum. The
principal and interest are due and payable in January 2003.

4-D
issued 59,549,081 shares of its common stock representing approximately 41% of its outstanding voting securities in a private placement transaction with specified
investors in accordance with Rule 506 of Regulation D and Section 4(2) of the Securities Act of 1933, as amended, which was consummated on or about April 26, 2001. The
common stock was issued at a per-share price of $0.21, in exchange for cancellations of indebtedness in the aggregate amount of $10,505,307 and cash in the aggregate sum of $2,000,000.

NOTE
7. RECENT ACCOUNTING PRONOUNCEMENTS

In
June 2001, the FASB completed SFAS No. 141, "Business Combinations," which requires all business combinations initiated after June 30, 2001 to be accounted for
under the purchase method. SFAS No. 141 also sets forth guidelines for applying the purchase method of accounting in the determination of intangible assets, including goodwill acquired in a
business combination, and expands financial disclosures concerning business combinations consummated after June 30, 2001. The application of SFAS No. 141 did not affect any of our
previously reported amounts included in goodwill and other intangible assets.

Effective
June 1, 2001, we early adopted SFAS No. 142, "Goodwill and Other Intangible Assets," which establishes new accounting and reporting requirements for goodwill and
other intangible assets. SFAS No. 142 requires that goodwill and certain intangibles no longer be amortized, but instead tested for impairment at least annually (second quarter 2002 goodwill
amortization otherwise would have been $327,000, and $654,000 for the three and six months ended March 31, 2002). Goodwill was tested for impairment by comparing the fair value of
4-D to its carrying value (including goodwill). Fair value was
determined using guidance from FASB Concept Statement No. 7, a market equity valuation methodology.

Based
on our initial impairment test, we determined that none of the goodwill recorded was impaired. Impairment adjustments recognized after adoption, if any, generally are required to
be recognized as operating expenses.

In
connection with adopting SFAS No. 142, we also reassessed the useful lives and the classification of our identifiable intangible assets and determined that they continue to be
appropriate. The value of our amortized intangible assets as of March 31, 2002 is $175,000.

In
October 2001, the FASB issued SFAS No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets". This statement establishes the accounting model
for long-lived assets to be disposed of by sale and applies to all long-lived assets, including discontinued operations. This new statement requires that those
long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or in discontinued operations. Therefore,
discontinued operations will no longer be measured at net realizable value or include amounts for operating losses that have not yet occurred. The Company has adopted SFAS No. 144 for fiscal
year ending September 30, 2002. The Company continues to assess the impact of this statement and will make any necessary adjustments, if appropriate.

NOTE
8. SUBSEQUENT EVENT

During
April 2002 an additional 6,153,845 shares were issued to specified investors in a private placement in accordance with Section 4(2) of the Securities Act of 1933, as
amended, in exchange for cash in the aggregate sum of $800,000. The participating investors include International Sequoia Investments Ltd., of which Martin Velasco Gomez, a member of
4-D's board of directors, is a major investor, and 4-D's board members Martin Egli, Enrique Maso, Galleon Graetz and Hans-Ueli Rihs.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following information should be read in conjunction with the condensed consolidated financial statements and the accompanying notes included in Item 1 of this
quarterly report, and the audited financial statements, accompanying notes and Management's Discussion and Analysis of Financial Condition and Results of Operations contained in our annual report on
Form 10-K for the fiscal year
ended September 30, 2001. This report may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties including, but not limited to,
those discussed in "Risks and Uncertainties." See "Risks and Uncertainties" for a discussion of some of the factors known to us that could cause reported financial information not to be necessarily
indicative of future results. We are not obligated to publicly release the results of any revisions to forward-looking statements to reflect events and circumstances arising after the date this report
is filed. This caution is made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

The
Company is experiencing serious operating and liquidity issues. These issues are discussed in more detail under "Results of Operations" and "Liquidity and Capital Resources" below.

OVERVIEW

4-D
Neuroimaging is engaged primarily in the business of developing, manufacturing, marketing and selling innovative medical imaging systems to medical research institutions.
The MSI systems developed by the Company measure magnetic fields created by the human body for the noninvasive diagnosis of certain medical disorders.

The
measurement of the body's magnetic fields by MEG/MSI provides information about the normal and abnormal functioning of the brain, heart and other organs. We are focusing on the use
of our technology for potential commercial market applications such as the diagnosis and planning for surgical treatment of epilepsy, and the functional mapping of areas of the brain at risk during
surgery for tumors and other lesions. We continue to investigate the potential applications of our technology for problems of the heart, spine, and other organs, as well as for neuro-psychiatric
disorders of the brain such as schizophrenia and closed-head trauma, and problems of the gastrointestinal system.

As
of March 2002, 58 MEG/MSI systems are installed in medical and research institutions worldwide, and more than 5,000 MEG/MSI examinations have been performed on patients and
control subjects at our application development sites. Related findings by us, and our collaborators, have been published in more than 200 scientific and medical papers. Since the first reimbursement
for MEG/MSI procedures was received in September 1993, more than 200 insurance companies have approved reimbursement on a case-by-case basis for certain MEG/MSI
procedures performed with our MEG/MSI systems.

trademark registration with the U.S. Patent and Trademark Office for the following marks: 4-D Neuroimaging, with and without the logo.

Our
current Magnes product line consists of the Magnes 2500 WH, the Magnes 3600 WH, and the Magnes 1300 C. The Magnes 2500 WH allows for examination of the entire brain at once and is
designed for evaluating ambulatory or critically ill patients in seated or fully reclined positions. As of March 31, 2002, we had shipped 15 Magnes 2500 WH systems. In fiscal 2000, we completed
the development of our next generation system, the Magnes 3600 WH that provides additional capabilities for the research market, and have delivered our first system to our customer. There are
currently two Magnes 1300 C's in the field primarily being used to look at organs in the body other than the brain.

Our
wholly owned subsidiary, Neuromag Oy, is engaged in the research, development and manufacturing of MEG/MSI systems in Helsinki, Finland. Neuromag Oy developed and sold its first
MEG/MSI system, the Neuromag 122 in 1994. Neuromag then introduced its next generation product, the Vectorview, in 1997. Both are whole head systems, designed to evaluate brain function.

The
current prices of our MEG/MSI systems generally range from approximately $1,000,000 to $2,500,000, depending upon system configuration. Major portions of our sales have been in
foreign markets. We have previously priced certain of our European sales in the currency of the country in which the product was sold and the prices of such products in dollars varied as the value of
the dollar fluctuated against the quoted foreign currency price. These value fluctuations may result in either a negative or positive cumulative translation adjustment. There can be no assurances that
currency fluctuations will not reduce the dollar return to the Company on such sales if made in the future. The foreign currency gain for the second quarter of fiscal 2002 was $101,000. Although at
March 31, 2002 and 2001, we did not have any open forward exchange contracts. We may in the future enter into forward exchange contracts to partially hedge such foreign currency exposure, if
appropriate.

Since
concentrating on the development of our MEG/MSI systems, our corporate strategy and commitment of resources have focused on long-term product applications and continued
product development.

We
believe that to date the relatively small number of proven medical applications for MEG/MSI systems, the lack of routine reimbursement for MEG/MSI procedures, and the uncertainty of
product acceptance in the U.S. market have limited system sales through fiscal 2001. With the issuance of CPT codes for MEG, we believe clinical acceptance of MEG/MSI systems may increase. It is not
possible to reliably predict the timing and extent of future product sales due to the long sales cycles and the uncertainties in the rate of impact the CPT codes will have on the market. We do not
anticipate multiple sales to the same end-user at current sales volumes, and the sale of one MEG/MSI system may have a significant impact on our financial position and results of
operations during any reporting period. As a result, quarterly and annual operating performance will continue to fluctuate significantly.

On
February 19, 2002, 4-D Neuroimaging announced that it had concluded a distribution agreement with Elekta Instruments, Inc., a company engaged in the
development, manufacture and sale of systems for radiosurgical therapy. Under the terms of this agreement, the marketing, sales and customer support resources of Elekta North and South America, a
division of Elekta, will be applied to the sale and support of 4-D Neuroimaging products in the neurosurgical market.

CRITICAL
ACCOUNTING POLICIES

The
preparation of financial statements, in conformity with accounting principles generally accepted in the United States, requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from these estimates. Results for the interim periods presented in

13

---

this report are not necessarily indicative of results that may be reported for any other interim period or for the entire fiscal year.

It
is our policy to recognize system sales revenues upon the final acceptance of the equipment by the customer. Additionally, as a part of our policy, we defer a portion of our systems
sales revenues related to future service activities and recognize them over a minimum period of one year.

We
have recorded a goodwill asset that arose from the acquisition of Neuromag Oy in 1999. This asset is tested for possible impairment at least on an annual basis in accordance with SFAS
No. 142, "Goodwill and Other Intangible Assets." See Note 7 for further discussion regarding SFAS No. 142.

RESULTS
OF OPERATIONS

Total
revenues for the second quarter and first six months of fiscal 2002 were $2,386,000 and $5,068,000, including $295,000 and $568,000 of service revenues, compared to $2,469,000 and
$5,599,000 of total revenues, including $89,000 and $313,000 of service revenues, for the second quarter and first six months of fiscal 2001. This decrease in total revenues was due primarily to the
recognition of revenue for two new MSI systems and one refurbished system in 2002 as compared to three new systems in 2001.

Cost
of revenues for the second quarter and first six months of fiscal 2002 were $1,963,000 and $4,195,000, compared to $2,465,000 and $3,969,000 for the second quarter and first six
months of fiscal 2001. The reduction in the second quarter of fiscal 2002 as compared to fiscal 2001 was primarily a result of re-statement, expensing certain project costs associated with
the production of Neuromag Oy's
Vectorview units in fiscal 2001. The increase in cost of revenues in the six month period was related to one system having a higher cost in fiscal 2002 compared to the prior year period.

Research
and development expenses for the second quarter and first six months of fiscal 2002 amounted to $308,000 and $675,000, compared to $425,000 and $1,137,000 for the second quarter
and first six months of fiscal 2001. The reduction in research and development expense in fiscal 2002 as compared to fiscal 2001 was due to a reduction in research and development personnel and
expense associated with certain research programs due to both our increased focus on marketing and sales and our liquidity position. We believe current hardware product lines fulfill current marketing
and sales requirements and do not require additional research and development expenditures at this time.

Marketing
and sales expenses amounted to $417,000 and $986,000 for the second quarter and first six months of fiscal 2002, compared to $418,000 and $932,000 for the second quarter and
first six months of fiscal 2001. Marketing and sales expenses increased due to higher recruitment and consulting expenses.

General
and administrative expenses totaled $642,000 and $1,364,000 for the second quarter and first six months of fiscal 2002, compared to $833,000 and $1,530,000 for the second quarter
and first six months of fiscal 2001. This decrease is primarily attributable to a reduction in professional services cost in fiscal 2002 and a reclassification of research and development cost at
Neuromag Oy in fiscal 2001.

We
have early adopted SFAS No. 142 in fiscal 2002 which requires that goodwill and certain intangibles no longer be amortized, but instead be tested for impairment at least
annually. Therefore, there was no goodwill amortization or impairment recognized in the second quarter and first six months of fiscal 2002, compared to $327,000 and $665,000 in the second quarter and
first six months for the same prior year periods. We performed an impairment analysis in consultation with an independent valuation firm in March 2002. Based on the analysis, it is our opinion
that 4-D has no goodwill impairment as of October 1, 2001 and for six months ended March 31, 2002. The Company continues to review the impact of this statement and will make
any necessary adjustments, as appropriate.

Interest
expense totaled $77,000 and $147,000 for the second quarter and first six months of fiscal 2002, compared to $324,000 and $655,000 during the second quarter and first six months
of fiscal 2001. The decrease in fiscal 2002 was the result of the cancellation of indebtedness in return for the issuance of common stock in the third quarter of fiscal 2001.

Other
income totaled $193,000 in the second quarter and $252,000 in the first six months of fiscal 2002, compared to $297,000 in the second quarter and $501,000 in the first six months
of fiscal 2001. The decrease is primarily attributable to no income from our investment in Magnesensors during the first
quarter of fiscal 2002 compared to $200,000 in income during the first quarter of fiscal 2001. During the first quarter of fiscal 2001, we notified Magnesensors that we would no longer continue to
provide a $200,000 guarantee of indebtedness due to the termination of our contractual obligations to do so and our liquidity concerns. We had been providing the guarantee, and under the equity method
of accounting for our investment in Magnesensors, had previously recorded our proportionate share of Magnesenors' losses to the extent of our debt guarantee.

Provision
for income taxes totaled $0 and $1,000 in the second quarter and first six months of fiscal 2002, compared to a tax benefit of $104,000 and $29,000 in the second quarter and
first six months of fiscal 2001. The reduced tax provision in the first quarter of 2002 was due to the use of tax loss carryforwards at the Company's Neuromag Oy subsidiary in fiscal 2002 as compared
to the first quarter of fiscal 2001.

Net
loss for the second quarter and first six months ended March 31, 2002 amounted to $826,000 and $2,040,000 compared to a net loss of $1,880,000 and $2,692,000 for the
comparable periods in the prior fiscal year. The decrease in net loss for the second quarter of fiscal 2002 as compared to the prior year period is primarily due to the reduction of research and
development expenses, general and administrative expenses and the discontinuance of goodwill amortization as required under SFAS No. 142.

LIQUIDITY
AND CAPITAL RESOURCES

We
continue to experience serious liquidity issues and incurred net losses of $4,501,000, $8,127,000 and $7,464,000 in fiscal 2001, 2000 and 1999, respectively. We had negative cash
flows from operations of $4,153,000, $5,217,000 and $8,602,000 in fiscal 2001, 2000 and 1999, respectively. For the quarter ended March 31, 2002, we incurred a net loss of $826,000 and had
negative cash flows from operations of $952,000. At March 31, 2002, we had an accumulated deficit of $112,953,000, shareholders' equity of $3,497,000 and a working capital deficiency of
$3,592,000. Neuromag Oy has bank guarantees related to a system for approximately $140,000 and other miscellaneous of approximately $44,000.

The
report of our independent public accountants on our financial statements included in the Form 10-K for the year ended September 30, 2001 contained a
modification related to our ability to continue as a going concern.

At
March 31, 2002, we had a working capital deficit of $3,592,000 as compared to $2,433,000 at September 30, 2001. Our increased working capital deficiency resulted
primarily from continued losses incurred in the first half of fiscal year 2002.

Capital
equipment expenditures totaled $134,000 including capitalization of a Magnetically Shielded Room for the second quarter of fiscal year 2002, compared to $11,000 for the second
quarter of fiscal year 2001. Capital expenditures will continue to remain low due to our liquidity concerns.

In
an effort to address our operational and liquidity issues, we continue to work with our lenders, are attempting to raise additional capital and are developing cost reduction measures
on a worldwide basis to bring our cost structure more in line with expected revenues. If we are not successful in initiating and executing these plans, we anticipate that capital, working capital and
debt service

15

---

requirements in fiscal 2002 will substantially exceed cash projected to be generated by MSI systems sales.

We
are authorized to offer and issue up to 15,000,000 shares of our common stock at a price not less than $0.13 per share through April 30, 2002. In the three month period ended
March 31, 2002, 7,692,308 shares were issued to an outside investor in a private placement transaction in accordance with Section 4(2) of the Securities Act of 1933, as amended, in
exchange for cash in the aggregate sum of $1,000,000.

During
April 2002 an additional 6,153,845 shares were issued on the terms previously authorized in a private placement in accordance with Section 4(2) of the Securities Act
of 1933, as amended, in exchange for cash in the aggregate sum of $800,000. The participating investors included Sequoia, of which Martin Velasco Gomez, a member of 4-D's board of
directors, is a major investor, and 4-D's board members Martin Egli, Enrique Maso, Galleon Graetz and Hans-Ueli Rihs.

Based
on our current expectation of anticipated cash receipts related to firm orders received and anticipated bookings of up to two additional MEG/MSI systems, we expect to have
sufficient cash to continue operations through July 2002 without taking into account cash requirements for maturities of our notes payable. Historically, we have raised additional capital
through our majority shareholders and related parties to fund continuing operations. We are working with these shareholders and related parties to renegotiate, reduce or repay our debt obligations and
to provide additional funding for operations. There can be no assurance that these sources of capital and funds will be available or that existing debt can be renegotiated on terms acceptable to the
Company, if at all.

In
December 1999, we acquired all of the issued and outstanding capital stock, or Shares, of Neuromag Oy pursuant to the terms of a share purchase agreement with Marconi. Under
the terms of the share purchase agreement, we paid Marconi a total of $10,000,000 in cash for the purchase of the Shares and agreed to pay Marconi between a minimum of $2,500,000 and a maximum of
$5,000,000 in royalties under an ancillary royalty agreement over an eight-year period and additional consideration dependent upon the occurrence of specified future events. The
acquisition was funded by a loan from AIG Bank.

On
or about April 26, 2001, we issued 59,549,081 shares of common stock, representing approximately 41% of our outstanding voting securities, in a private placement transaction
with specified investors in accordance with Rule 506 of Regulation D and Section 4(2) of the Securities Act of 1933, as amended. The common stock was issued at a
per-share price of $0.21, in exchange for cancellations of indebtedness in the aggregate amount of $10,505,307 and cash in the aggregate sum of $2,000,000.

The
$10,505,307 in cancellations of indebtedness consisted of a partial cancellation of indebtedness in the amount of $8,951,000 by AIG according to a letter agreement dated on or about
April 25, 2001, between AIG and 4-D, full cancellations of indebtedness in the amounts of $872,867 and $224,875 by Swisspartners, a full cancellation of indebtedness in the amount
of $224,875 by MATRUST, S.L., a full cancellation of indebtedness by Sequoia in the amount of $224,875, and a full cancellation of indebtedness in the amount of $6,815 from Amaldos, S.A. The full
cancellations of indebtedness entered into between 4-D and each of Amaldos, S.A., MATRUST, S.L., Sequoia and Swisspartners represent the portion of the debt assigned to each such entity by
BDN, a Spanish company owned by three members of our board of directors, Martin Egli, Enrique Maso and Martin Velasco Gomez, upon its reduction of capital. Mr. Egli is also a member of the
board of directors of AIG and is a managing partner of Swisspartners. Dr. Maso is a majority shareholder in MATRUST, S.L. Mr. Velasco Gomez is a major investor in Sequoia.

The remainder of the AIG loan was restructured in connection with the April 2001 private placement transaction. As restructured, the loan in the principal amount of $3,357,000
from AIG Bank matures in July 2002 and the interest rate was set at 6.8% per annum until April 26, 2002, at which time the interest rate was reduced to 4.4% per annum for the remainder
of the loan term. As amended, the AIG loan is secured by a pledge and assignment by Scaloway, a guarantee in the amount of $2,200,000 by Bank Julius Baer & Co. AG and all of the issued and
outstanding shares of Neuromag Oy, our wholly-owned subsidiary. If we default under the AIG loan, then AIG has the right to exercise its security interests and take ownership of Neuromag Oy. Also, in
connection with the private placement transaction, Scaloway agreed to convert certain assets pledged and assigned by Scaloway into an indirect ownership of all 42,623,810 shares of our common stock
issued to AIG. Scaloway has sole voting and dispositive power over these shares. Mr. Velasco Gomez, a member of our board of directors, is the beneficial owner of Scaloway.

Swisspartners,
one of our principal shareholders, invested $2,000,000 in cash into us through its purchase of additional common stock in the April 2001 private placement
transaction. In connection with the purchase by Swisspartners, our board of directors approved an increase in the current size of our board of directors from eight to nine to appoint
Mr. Hans-Ueli Rihs to serve as a member of the board of directors effective May 2001. Mr. Hans-Ueli Rihs is also a member of the board of directors of
Swisspartners. The $2,000,000 was used for general corporate purposes and to begin to focus our marketing efforts and leveraging the issuance of CPT codes for MEG.

Prior
to its acquisition by 4-D, Neuromag Oy borrowed a total of 3,140,000 in Finnish Markka, or FIM, which equaled approximately $460,000 USD at March 31, 2002, from
TEKES at the Finnish state base interest rate minus 1%, subject to a minimum rate of 3%. The future repayment date for principal and related accrued interest outstanding under this loan is dependent
upon Neuromag Oy generating sufficient distributable equity based upon the statutory financial accounts prepared in accordance with Finnish generally accepted accounting principles, in the future.

In
January 2002, 4-D obtained two unsecured loans from the Company's board of directors, each in the amount of $125,000, with an interest rate of 8% per annum. The
principal and interest are due and payable on January 2003.

The
accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed above and as shown in the accompanying
consolidated financial statements, the Company has operating and liquidity concerns that raise substantial doubt about the Company's ability to continue as a going concern. There can be no assurance
that we will be
able to successfully improve our operating results and restructure our indebtedness or that our liquidity and capital resources will be sufficient to maintain our normal operations. The financial
statements do not include any adjustments relating to the recoverability and classification of asset carrying amounts or the amount and classification of liabilities that might result should the
Company be unable to continue as a going concern.

FACTORS
THAT MAY AFFECT FUTURE RESULTS

This
quarterly report on Form 10-Q may contain forward-looking statements that involve risks and uncertainties. Such statements include, but are not limited to,
statements containing the words "believes", "anticipates", "expects", "estimates", and words of similar import. The Company's results could differ materially from any forward-looking statements, which
reflect management's opinions only as of the date hereof, as a result of factors, such as those more fully described under "Risks and Uncertainties". The Company undertakes no obligation to publicly
release the results of any revisions to these forward-looking statements. Readers should carefully review the risk factors set forth below as well as other factors addressed in this report, our annual
report on Form 10-K and in other documents we file from time to time with the Securities and Exchange Commission.

RISKS
AND UNCERTAINTIES

We
face the following risks associated with our business operations:

We are uncertain with respect to additional funding and may not be able to meet our future capital needs. As a result, there is substantial doubt about our
ability to continue to operate as a going concern.

We
require additional capital to fund working capital and debt service on an ongoing basis. We restructured our loans in April 2001 and have a principal balance due to AIG Private
Bank, Ltd., Zurich Switzerland, in July 2002 of $3,357,000 plus related interest. We will need to obtain additional financing to fund operations and repay the notes and interest. If we
default under the AIG loan, AIG could exercise its rights in its security interests and take ownership of Neuromag Oy. We may not be able to arrange additional financing or restructure our debt on
terms acceptable to us, if at all.

If we continue to incur operating losses and negative cash flows from operations, we may be unable to continue our operations.

Our
financial position reflects that we have been focused on research and development and a commercial MEG/MSI market has not yet developed, resulting in only low volume sales to medical
research institutions. Our net losses in the last three years have been as follows:



In
the last three years our negative cash flows from operations have been as follows:



At
March 31, 2002, our accumulated deficit was $112,953,000, our shareholders' equity was $3,497,000 and we had negative working capital of $3,592,000. Our negative working
capital at March 31, 2002 resulted primarily from continued losses incurred in the first quarter of fiscal year 2002. In an effort to address our operational and liquidity issues, we continue
to work with our lenders, are attempting to raise additional capital and are developing cost reduction measures on a worldwide basis to bring our cost structure more in line with expected revenues. If
we are not successful in initiating and executing these plans, we anticipate that capital, working capital and debt service requirements in fiscal 2002 will substantially exceed cash projected to be
generated by MEG/MSI systems sales.

If we fail to obtain an adequate level of reimbursement for MEG/MSI procedures by third party payors, sales will suffer.

Our
commercial success is also highly dependent on reimbursement for procedures using the MEG/MSI systems. With the issuance of CPT codes by the AMA MEG/MSI has moved one step closer to
having routine reimbursement. The level of reimbursement currently established is not sufficient to
provide for an economically viable MEG/MSI installation. This assignment is currently under review but there can be no assurance that an adequate level of reimbursement for MEG/MSI will result from
the review. Without adequate reimbursement levels we will be more dependent on sales in the research market.

Our management and controlling shareholders, which together control a majority of our common stock, may control our operations and make decisions that you do not
consider in your best interest.

Our
present directors, executive officers and principal shareholders and their affiliates beneficially own a majority of our outstanding common stock. As a result, if all or some of
these shareholders were

18

---

to act together, they would be able to exercise significant influence over all matters requiring shareholder approval, including the election of directors and approval of significant corporate
transactions. Such concentration of ownership may also have the effect of delaying or preventing a change in our control that may be favored by other shareholders.

If we are unable to identify additional clinical applications for our MEG/MSI systems, there will be no commercially viable markets for our
products.

Currently,
there are only a few established diagnostic uses for MEG/MSI systems known by the medical industry. A commercial market may never develop for multiple uses of our products. A
continued lack of clinical applications and commercial market for our MEG/MSI systems will have a material adverse impact on our financial position, results of operations and cash flows.

Our vendors may not continue providing favorable credit terms.

Due to our liquidity issues, we have extended vendor payments beyond normal credit terms. If our major vendors were to decline further credit or require cash on
delivery payments, our financial position, results of operations and cash flows would be adversely impacted.

Integrating 4-D Neuroimaging and Neuromag Oy will be difficult.

Our
acquisition of Neuromag Oy in December 1999 brought together two previous international competitors. Risks common to such mergers include:



Also,
it is possible that despite a successful integration, future results of operations of the merged Company do not meet expectations, due to other risks discussed in this report or
other documents filed with the SEC, and other factors.

If we are unable to develop additional products, our ability to commercialize our products will be adversely impacted.

Our
success may be limited by our dependence on our current line of MEG/MSI systems. We are currently dependent on sales of our MEG/MSI systems to basic research institutions that
represent a market of limited size. Our current product line may not fully meet the needs of a commercial clinical market and we may be required to develop additional products directly suited to an
emerging set of needs from this market. Our financial results may be materially adversely affected if our current line of
MEG/MSI products does not fully meet the commercial applications that emerge, or we are not able to offer new products in a timely and cost effective manner.

If discoveries or developments of new technologies occur, our products and technology may become obsolete.

Our
industry is characterized by rapid technological change, which may also impact our commercial success. Competitors may develop products using other technologies or may improve
existing products. This competition may reduce the size of the potential market for our products or make them obsolete or non-competitive. Competitors may also develop new or different
products using technology or imaging modalities that provide, or are perceived as providing, greater value than the Company's products. Our financial position and results of operations will be
materially adversely affected if such competitive developments occur.

If we fail to compete successfully, our revenues and operating results will be adversely affected.

Historically,
our industry has been characterized by ongoing price competition. Our competitors compete with us for the currently limited number of whole head systems being purchased
worldwide. The future profitability of our systems may be negatively impacted by this competition.

If new government legislation is enacted or unfavorable medical industry trends arise, we may be unable to sell our products and our revenues will
suffer.

We
cannot predict what adverse effect, if any, future legislation or FDA regulations may have on the MEG/MSI market and our financial results. Medical industry cost containment trends
may impose restrictions on sizeable third-party reimbursements for diagnostic procedures, limiting the market opportunity. Further, if federal or foreign government agencies or any state legislature
enacts legislation or guidelines relating to our business or the health care industry that create additional business hurdles, including legislation relating to third party reimbursement, our
financial position and results of operations could be negatively affected.

If foreign currency exchange rates fluctuate, our return on sales in U.S. dollars may suffer

A significant portion of our sales to date have been in foreign markets. Revenues from international sales represented 57% of our revenues of MEG/MSI systems for
the year ended September 30, 2001
compared to 99% in fiscal 2000. We expect that revenues from international sales will continue to represent a significant portion of our annual revenues. Because we sell in foreign markets, we are
exposed to potential risks of increases and decreases in foreign currency exchange rates. Although at March 31, 2002 and 2001 we did not have any open forward exchange contracts, upon occasion,
we may enter into forward exchange contracts to partially hedge (or protect) against such foreign currency exchange risks. Fluctuations may reduce the return in U.S. dollars that we actually receive
on our sales. We believe that a hypothetical 10% change in foreign currency exchange rates would not materially change our current financial position and results of operations. However, these risks
may become material as our sales increase or dramatic currency fluctuations occur from outside events.

Our success is dependent upon our ability to attract and retain qualified scientific and management personnel.

The
loss of services of any one of our executive management or key scientific personnel would delay our ability to execute our business plans and reduce our ability to successfully
develop and commercialize products, maintain good customer relationships and compete in the marketplace. There can be no assurance that we will be able to hire, train or retain such qualified
personnel.

In
addition, the loss of the services of Dr. Buchanan, who currently serves as our President, Chief Executive Officer and Principal Financial Officer, would have a material
adverse effect on our prospects. Currently none of the executive officers of the Company have an employment agreement or contract with us; all are "at-will" and under no specified term
arrangements.

If our products produce unreliable diagnostic information, it may result in a liability, which would adversely impact our financial
condition.

Although
our products are noninvasive and diagnostic in nature, treatment courses based on the information generated by our instruments may be unreliable or result in adverse effects.
This possibility exposes us to the risk of product liability claims. While we carry product liability insurance, there is no assurance that such insurance will be adequate, will be available in the
future at a level and cost that is appropriate, or available at all, or that a product liability claim would not adversely affect our business prospects, financial position, results of operations and
cash flows.

Our stock price is highly volatile and subject to swings based on sales and other market conditions.

The
market prices for securities of companies with newly emerging markets have historically been highly volatile, and their stock price from time to time has experienced significant
price and volume fluctuations that are unrelated to the operating performance of such companies. Moreover, our relatively low trading volume increases the likelihood and severity of volume
fluctuations, which likely will result in a corresponding increase in the volatility of our common stock price. Factors such as announcements of complex technological innovations or new sales,
governmental regulations, developments in patent or other proprietary rights, developments in the Company's relationships with collaborative partners, general market conditions and the timing of
decisions by our existing shareholders to sell large positions of our common stock may have a significant effect on the market price of the Company's common stock. Fluctuations in financial
performance from period to period, or acceleration of any of our debt by our lenders, also may have a significant impact on the market price of the common stock.

If Elekta North and South America is ineffective in distribution our products in the U.S., sales may suffer.

Historically,
we have undertaken the sales and support of our products in the U.S. directly with our own staff. We have now entered into a distribution agreement with Elekta North and
South America. We believe the resources that can now be brought to bear on the sales of our products in the neurosurgery market will lead to increased sales. But it is possible that this new
distributor will not prove effective in marketing our products.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

On March 31, 2001, the Company had approximately $12,600,000 outstanding under London Interbank Offered Rate based variable rate indebtedness. Subsequent
to March 31, 2001, we retired approximately $10,500,000 of our outstanding debt and restructured approximately $3,357,000 of our remaining debt owed to AIG Private Bank Ltd. in
connection with a private placement transaction which was consummated on or about April 26, 2001. Under the restructured loan terms, the maturity date has been extended to July 31, 2002
and the interest rate on the AIG loan was fixed at 6.8% per annum until April 26, 2002, at which time the interest rate was reduced to 4.4% per annum for the remainder of the loan term. Because
a major portion of the Company's current indebtedness is at a fixed rate, the Company does not expect changes in interest rates to have a material adverse effect on the Company during the 2002 fiscal
year. See Part I, Item 2, "Liquidity and Capital Resources" of this report for additional detail with regard to the restructuring of the AIG loan and the private placement transaction.

For
additional information required by this item regarding market risks related to fluctuations in foreign currency exchange rates, see our discussion under "Risks and
UncertaintiesIf foreign currency exchange rates fluctuate, our return on sales in U.S. dollars may suffer" under Item 2Management's Discussion and Analysis of Financial
Condition and Results of Operations.

PART II. OTHER INFORMATION

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

We are authorized on behalf of the Company to offer and issue up to 15,000,000 shares of the Company's common stock at a price not less than $0.13 per share. In
the three month period ended March 31, 2002, 7,692,308 shares were issued to a non-affiliated, individual investor in a private placement transaction in accordance with
Section 4(2) of the Securities Act of 1933, as amended, in exchange for cash in the aggregate sum of $1,000,000. This private placement was consummated on March 11, 2002.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

The Company held its annual meeting of shareholders on March 15, 2002 and proxies for such meeting were solicited pursuant to Regulation 14. There
was no solicitation in opposition to the Company's nominees for directors as listed in the proxy statement and all such nominees were elected. In addition, the following matters were adopted by the
shareholders at the annual meeting.
