The extrinsic flood image evaluates the uniformity of: Detector and collimator Collimator only Neither detector nor collimator Detector only 2. When performing daily intrinsic floods, a point source of Tc-99m is placed five crystal dimensions away and centered over the detector. A point source should produce a measured counting rate not greater than: 35,000 cps 5,000 cps 15,000 cps 25,000 cps 3. Increasing the thickness of the scintillation detector will result in the detector: Increased sensitivity and increased resolution Decreased and decreased resolution Decreased and increased resolution Increased sensitivity and decreased resolution 4. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Geiger-Mueller detector Glucose meter Thyroid probe Well counter 5. Well-counter calibration data of a positron emission tomography (PET) scanner are applied for: Energy window calibrations. Attenuation correction. Standardized uptake value (SUV) calculation. Image reconstruction. 6. 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 emission data. The absence of any material in the field of view (FOV). The absence of technologist. The absence of patient. 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: 2.5, 3, 4, and 4.5 mm in width 2, 2.5, 3, and 4 mm in width 3, 4, 5, and 6 mm in width 1, 2, 3, and 4 mm in width 8. If generator elute contains 635 mCi of Tc-99m, what is the maximum amount of Mo-99 allowed? (0.15 uCi Mo-99 per mCi Tc-99m) 0.54 uCi 95.3 uCi 64.2 uCi 0.15 mCi 9. 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: Flood uniformity Peaking linearity Spatial resolution Energy resolution 10. 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: 662 keV gamma ray 388 keV gamma ray 133 keV gamma ray 637 keV gamma ray 1 out of 10 Time is Up!
