New Jersey Administrative Code › Title 7 - ENVIRONMENTAL PROTECTION › Chapter 28 - RADIATION PROTECTION PROGRAMS › Subchapter 22 - QUALITY ASSURANCE PROGRAMS FOR MEDICAL DIAGNOSTIC X-RAY INSTALLATIONS › Section 7:28-22.10 - Medical Physicist's Computed Tomography QC Survey

Current through Register Vol. 56, No. 14, July 15, 2024
(a) The registrant of any medical diagnostic computed tomography equipment used in the healing arts shall develop and continuously implement a quality assurance program. Such a program shall include an initial and thereafter an annual (not to exceed 14 months) Medical Physicist's Computed Tomography QC Survey performed by a qualified medical physicist for the supervision of quality assurance programs for computed tomography equipment. The Medical Physicist's Computed Tomography QC Survey shall include the elements identified in the Table 6, Medical Physicist's Computed Tomography QC Survey, below. If the standard for any test in Table 6 refers to a manufacturer's specification and no such specification exists, then that standard does not apply.

(b) A qualified medical physicist for the supervision of quality assurance programs for computed tomography equipment may not delegate any items in Table 6, Medical Physicist's Computed Tomography QC Survey, above.
(c) The qualified medical physicist for the supervision of quality assurance programs for computed tomography equipment shall be fully responsible for the Medical Physicist's Computed Tomography QC Survey and all of its measurements, conclusions and recommendations.
(d) All Medical Physicist's Computed Tomography QC Survey reports shall be signed by the qualified medical physicist for the supervision of quality assurance programs for computed tomography equipment.
(e) For the Computed Tomographic QC Survey
1. If any of the Computed Tomographic QC Survey test results from items 1 through 4 in Table 6, Medical Physicist's Computed Tomography QC Survey, above indicate that the CT equipment does not meet the standards established in Table 6, the registrant shall immediately initiate corrective actions to meet the standards. All corrective actions shall be completed within 15 days.
2. If any of the Computed Tomographic QC Survey test results from items 5 through 11 in Table 6, Medical Physicist's Computed Tomography QC Survey, above indicate that the CT equipment does not meet the standards established in Table 6, the registrant shall immediately initiate corrective actions to meet the standards. All corrective actions shall be completed within 30 days.
3. For item 12 in Table 6, Medical Physicist's Computed Tomography QC Survey, above, the medical physicist shall ensure that both the adult and pediatric scan protocols are separate and unique.
4. For item 13 in Table 6, Medical Physicist's Computed Tomography QC Survey, above, the medical physicist shall review the completed QC test records that have been performed by the registrant for the previous year to ensure the tests were performed properly and corrective actions taken.
5. For item 14 in Table 6, Medical Physicists Computed Tomography QC Survey, above, the medical physicist shall prepare a report that reviews the overall quality assurance program being carried out by the registrant and contains:
i. Raw data and results of the medical physicists equipment tests performed in accordance with items 1 through 12 in Table 6, Medical Physicists Computed Tomography QC Survey, above and recommendations based on these tests; and
ii. Results and recommendations based on the medical physicists review performed in accordance with item 13 in Table 6, Medical Physicists Computed Tomography QC Survey, above.
