What are the requirements of the annual survey?
Once a year, each facility must be surveyed by a medical physicist or by someone in training under his or her direct supervision. The survey will include:
(1) performance of the annual tests described in the regulations (Table 2 above and the QC tests for other modalities, if applicable) and the weekly phantom image quality test;
(2) review of the results of the QC tests conducted by the facility (Table 1 above), as well as of written documentation of any corrective actions taken and their results; and
(3) a report, which must be provided to the facility within 30 days of the date of the survey, that includes a summary of the areas tested and reviewed and recommendations for necessary improvements.
The annual tests must be performed using technique factors and test conditions as stated in the regulations whenever those factors are specified. Otherwise, technique factors that are clinically used in the facility for which the annual survey is conducted should be used whenever possible. For test procedures that determine dose to the average breast, the same kVp value (within +/- 1 kVp of that used clinically for the average breast) must be used for measuring both the entrance skin exposure and the HVL.
The report must be dated and signed by (or contain the identification of) the medical physicist performing or supervising the survey and any other individual who performed or assisted in the survey. If the survey is done over a period of time, the dates of completion of the individual parts must be indicated in the report.
