The extrinsic flood image evaluates the uniformity of: Detector and collimator Neither detector nor collimator Detector only Collimator only 2. The blank scan is performed daily on Positron Emission Tomography (PET) scanners using a Ge-68 transmission source. The term blank scan reflects: The absence of patient. The absence of any material in the field of view (FOV). The absence of emission data. The absence of technologist. 3. The daily quality control for dose calibrator includes a constancy check typically performed with small amounts of Cobalt-57 or Cesium-137. Cs-137 has a half-life of 30 years and produces: 637 keV gamma ray 388 keV gamma ray 133 keV gamma ray 662 keV gamma ray 4. All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT: SPECT phantom Center of rotation (COR) calibration Uniformity correction matrix Multiple head registration (MHR) validation 5. The maximum permissible limit of Al+3 in Tc-99m eluate is set by? Society of Nuclear Medicine (SNM) Food and Drug Administration (FDA) U.S. Pharmacopeia Nuclear Regulatory Commission (NRC) 6. The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called: Geometry Accuracy Constancy Linearity 7. Spatial resolution and spatial linearity of a gamma-camera is assessed with a 4-quadrant bar phantom which consists of four sectors of lead bars and intervening plastic strips: 2, 2.5, 3, and 4 mm in width 3, 4, 5, and 6 mm in width 2.5, 3, 4, and 4.5 mm in width 1, 2, 3, and 4 mm in width 8. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Geometry Battery check Constancy Accuracy 9. Well-counter calibration data of a positron emission tomography (PET) scanner are applied for: Standardized uptake value (SUV) calculation. Image reconstruction. Energy window calibrations. Attenuation correction. 10. The gamma-camera is the most widely used imaging piece of equipment in nuclear medicine. The performance parameters of a routine gamma-camera quality control (QC) program include all of the following EXCEPT: Spatial resolution Energy resolution Peaking linearity Flood uniformity 1 out of 10 Time's upTime is Up!
