Well-counter calibration data of a positron emission tomography (PET) scanner are applied for: Attenuation correction. Standardized uptake value (SUV) calculation. Energy window calibrations. Image reconstruction. 2. All of the following quality control (QC) tests are performed in nuclear medicine department to assess the reproducibility of radiation counter EXCEPT: The chi-squared test The constancy test The relative error The reliability factor 3. Every received package holding radioisotopes must be logged in properly. The incoming package logbook must include all of the following data EXCEPT: Received activity Product name Driver’s name Date 4. 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 5. The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called: Accuracy Constancy Linearity Geometry 6. 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 637 keV gamma ray 133 keV gamma ray 7. Which of the following is a gas-filled radiation survey instrument? Thermoluminescent dosimeter (TLD). Geiger-muller counters. Optically stimulated luminescence (OSL) dosimeter. Pocket ionization chamber. 8. To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT: Constancy Accuracy Geometry Battery check 9. 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 activity within the patient, UP counts patient samples. They measure activity in units of counts or counts per minute. They are solid sodium iodide crystal detectors. WC counts patient samples, UP counts activity within the patient. 10. All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT: Center of rotation (COR) calibration SPECT phantom Uniformity correction matrix Multiple head registration (MHR) validation 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-03-25T11:27:42+03:00مارس 25th, 2021|لا توجد تعليقات شارك هذه الصفحة, واترك رأيك حول الموضوع باستخدام وسيلة التواصل التي تناسبك FacebookXLinkedInWhatsAppPinterestEmail عن: ناصر المطيري كبير أخصائيي الطب النووي في مستشفى حفر الباطن المركزي و مؤسس موقع نيوكليرمد. اترك تعليقاًCancel reply
