  7. R 325.5701 Purpose and scope • Part 15 - CT used for diagnostic imaging in the healing arts • Exemptions • Low powered CT units < 5 kilowatts • PET/CT and SPECT • Therapy simulation • Intra-operative guidance tomography • Other applicable IRR • CON CT review standards December 10, 2010 7

  8. R 325.5703 Definitions • 21 C.F.R. 1020.33, “Computed tomography (CT) equipment” (June 10, 2005) • “Annual” – 12 consecutive months December 10, 2010 8

  9. R 325.5703 Definitions “CT medical event” means an unintended event where a physician determines that actual damage has occurred to an organ or a physiological system of an individual due to or suspected to be due to exposure to diagnostic radiation from a CT scanner.

  10. R 325.5703 Definitions • “Medical physicist” means a person trained in evaluating the performance of CT scanners, related equipment, and facility quality assurance programs and who meets the requirements in R 325.5707. • “Radiologic technologist” means an individual specifically trained in the use of radiographic equipment and the positioning of patients for radiographic examinations and who meets the requirements in R 325.5705. December 10, 2010 10

  11. R 325.5703 Definitions • “Traceable to a national standard” means an instrument is calibrated at either the national institute of standards and technology (NIST) or at a calibration laboratory that participates in a proficiency program with the NIST at least once every 2 years and the results of the proficiency test conducted within 24 months of calibration show agreement within ± 3% of the national standard in the appropriate energy range.
