    I have reviewed this Quarterly Report on Form 10-Q of
Analogic Corporation:2.
    
    Based on my knowledge, this report does not contain any
untrue statement of a material fact or omit to state a material fact
necessary to make the statements made, in light of the circumstances
under which such statements were made, not misleading with respect to the
period covered by this report;3.
    
    Based on my knowledge, the financial statements, and
other financial information included in this report, fairly present in
all material respects the financial condition, results of operations and
cash flows of the registrant as of, and for, the periods presented in
this report;4.
    
    The registrants other certifying officer(s) and I are
responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
internal control over financial reporting (as defined in Exchange Act
Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
 a)
    
    Designed such disclosure controls and
procedures, or caused such disclosure controls and procedures to
be designed under our supervision, to ensure that material
information relating to the registrant, including its
consolidated subsidiaries, is made known to us by others within
those entities, particularly during the period in which this
report is being prepared;b)
    
    Designed such internal control over
financial reporting, or caused such internal control over
financial reporting to be designed under our supervision, to
provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements
for external purposes in accordance with generally accepted
accounting principles;c)
    
    Evaluated the effectiveness of the
registrants disclosure controls and procedures and presented in
this report our conclusions about the effectiveness of the
disclosure controls and procedures, as of the end of the period
covered by this report based on such evaluation; andd)
    
    Disclosed in this report any change in
the registrants internal control over financial reporting that
occurred during the registrants most recent fiscal quarter (the
registrants fourth fiscal quarter in the case of an annual
report) that has materially affected, or is reasonably likely to
materially affect, the registrants internal control over
financial reporting; and
 5.
    
    The registrants other certifying officer(s) and I have
disclosed, based on our most recent evaluation of internal control over
financial reporting, to the registrants auditors and the audit committee
of the registrants board of directors (or persons performing the
equivalent functions):
 a)
    
    All significant deficiencies and
material weaknesses in the design or operation of internal
control over financial reporting which are reasonably likely to
adversely affect the registrants ability to record, process,
summarize and report financial information; andb)
    
    Any fraud, whether or not material, that
involves management or other employees who have a significant
role in the registrants internal control over financial
reporting.
