Medical Physicist: CT (Revised 12-12-19)
Modified on: Fri, 13 Dec, 2019 at 8:22 AM
The qualified medical physicist:
Must be familiar with: the principles of imaging physics and of radiation protection; guidelines of the National Council on Radiation Protection and Measurements; laws and regulations pertaining to the performance of the equipment being tested; function, clinical uses, and performance specifications of imaging equipment; and calibration processes and limitations of instruments used for performance testing.
Should be available for consultation regarding patient dosimetry issues within a reasonable period of time.
Is responsible for the conduct of all surveys of the equipment. The medical physicist may be assisted by properly trained individuals in obtaining data. The medical physicist is responsible for determining if the assisting individual is “properly trained.” These individuals must be approved by the medical physicist in the techniques of performing tests, the function and limitations of the imaging equipment and test instruments, the reasons for the tests, and the importance of the test results. Any assisting individual must be under the direct supervision of the medical physicist during the surveys (direct supervision means that the medical physicist must be present in the facility and immediately available to furnish assistance and direction throughout the performance of the procedure; direct supervision does not require that the medical physicist be present in the room when the procedure is being performed; teleconferencing does not constitute direct supervision).
Must: be present during the surveys; review, interpret, and approve all data; and provide a report of the conclusions with his/her signature.
Effective January 1, 2010, all medical physicists providing these services must meet the minimum criteria in the table below.
