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: 15,000 cps 35,000 cps 5,000 cps 25,000 cps 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: Flood uniformity Energy resolution Spatial resolution Peaking linearity 3. 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 Planar imaging SPECT imaging 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? They are solid sodium iodide crystal detectors. 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. 5. 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 6. The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called: Accuracy Constancy Linearity Geometry 7. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Glucose meter Thyroid probe Well counter Geiger-Mueller detector 8. 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 emission data. The absence of patient. The absence of any material in the field of view (FOV). 9. The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called: Geometry Constancy Linearity Accuracy 10. Which of the following quality control procedures is NOT performed to ensure proper operation of the survey meter? Accuracy Battery check Sealed source check Calibration 1 out of 10 Time's upTime is Up! بواسطة ناصر المطيري|2021-09-20T14:26:46+03:00أبريل 15th, 2021|مراقبة الجودة|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
