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: 3, 4, 5, and 6 mm in width 2.5, 3, 4, and 4.5 mm in width 2, 2.5, 3, and 4 mm in width 1, 2, 3, and 4 mm in width 2. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Accuracy Constancy Geometry Battery check 3. 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 Center of rotation (COR) calibration Uniformity correction matrix 4. Well Counter (WC) and Uptake Probe (UP) are two detectors commonly configured to a single computer. Which of the following statements describing their properties is INCORRECT? WC counts patient samples, UP counts activity within the patient. They measure activity in units of counts or counts per minute. WC counts activity within the patient, UP counts patient samples. They are solid sodium iodide crystal detectors. 5. 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 relative error The chi-squared test The reliability factor 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) 0.54 uCi 95.3 uCi 0.15 mCi 64.2 uCi 7. The extrinsic flood image evaluates the uniformity of: Neither detector nor collimator Detector and collimator Collimator only Detector only 8. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Glucose meter Well counter Geiger-Mueller detector Thyroid probe 9. 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 25,000 cps 15,000 cps 10. The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called: Accuracy Geometry Constancy Linearity 1 out of 10 Time is Up!
