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 3, 4, 5, and 6 mm in width 1, 2, 3, and 4 mm in width 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: Peaking linearity Flood uniformity Spatial resolution Energy resolution None 3. 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? + 2.0 - 2.0 - 1.7 + 1.7 None 4. The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called: Geometry Accuracy Constancy Linearity None 5. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Geometry Accuracy Battery check Constancy None 6. All of the following quality control (QC) tests are performed in nuclear medicine department to assess the reproducibility of radiation counter EXCEPT: The constancy test The chi-squared test The relative error The reliability factor None 7. 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 technologist. The absence of any material in the field of view (FOV). The absence of patient. The absence of emission data. None 8. The quality control procedure known as survey meter calibration is usually performed by: The radiation safety officer The physicist The technologist The lead technologist None 9. 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) 95.3 uCi 0.54 uCi 64.2 uCi 0.15 mCi None 10. Which of the following quality control procedures is NOT performed to ensure proper operation of the survey meter? Sealed source check Calibration Battery check Accuracy None 1 out of 10 Time's upTime is Up!
