The shield and the decay method are two different approaches to evaluate: Gamma Camera linearity Dose calibrator linearity Effective dose measurement Half-value layer thickness None 2. 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: Energy resolution Spatial resolution Flood uniformity Peaking linearity None 3. 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 patient. The absence of technologist. None 4. The quality control procedure known as survey meter calibration is usually performed by: The technologist The radiation safety officer The lead technologist The physicist None 5. 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 Uniformity correction matrix Center of rotation (COR) calibration SPECT phantom None 6. 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) 0.15 mCi 64.2 uCi 95.3 uCi 0.54 uCi None 7. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Constancy Geometry Accuracy Battery check None 8. The maximum permissible limit of Al+3 in Tc-99m eluate is set by? Society of Nuclear Medicine (SNM) U.S. Pharmacopeia Nuclear Regulatory Commission (NRC) Food and Drug Administration (FDA) None 9. 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 133 keV gamma ray 388 keV gamma ray 637 keV gamma ray None 10. If expected value of the long-lived source is 120 mCi and actual reading obtained from dose calibrator is 122 mCi, what is the percentage error of that reading? + 1.7 - 1.7 - 2.0 + 2.0 None 1 out of 10 Time's upTime is Up!
