All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT: Multiple head registration (MHR) validation SPECT phantom Uniformity correction matrix Center of rotation (COR) calibration None 2. 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 2.5, 3, 4, and 4.5 mm in width 1, 2, 3, and 4 mm in width 3, 4, 5, and 6 mm in width None 3. Which of the following is a gas-filled radiation survey instrument? Pocket ionization chamber. Geiger-muller counters. Optically stimulated luminescence (OSL) dosimeter. Thermoluminescent dosimeter (TLD). None 4. 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 662 keV gamma ray 133 keV gamma ray None 5. Increasing the thickness of the scintillation detector will result in the detector: Increased sensitivity and decreased resolution Decreased and increased resolution Increased sensitivity and increased resolution Decreased and decreased resolution None 6. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Geometry Constancy Accuracy Battery check None 7. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Geiger-Mueller detector Thyroid probe Glucose meter Well counter None 8. The shield and the decay method are two different approaches to evaluate: Effective dose measurement Dose calibrator linearity Gamma Camera linearity Half-value layer thickness None 9. Which of the following quality control procedures is NOT performed to ensure proper operation of the survey meter? Calibration Accuracy Sealed source check Battery check None 10. The center of rotation (COR) of gamma-cameras is a key quality control procedure performed to assess capability of the nuclear medicine cameras to perform: Dynamic scanning Dual phase scanning SPECT imaging Planar imaging None 1 out of 10 Time's upTime is Up!
