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 1, 2, 3, and 4 mm in width 2, 2.5, 3, and 4 mm in width 2.5, 3, 4, and 4.5 mm in width 2. The quality control procedure known as survey meter calibration is usually performed by: The physicist The lead technologist The technologist The radiation safety officer 3. Increasing the thickness of the scintillation detector will result in the detector: Decreased and increased resolution Increased sensitivity and increased resolution Decreased and decreased resolution Increased sensitivity and decreased resolution 4. The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the: Glucose meter Geiger-Mueller detector Well counter Thyroid probe 5. The quality control procedure performed on the dose calibrator with all the dose configurations used in the nuclear medicine department is called: Constancy Geometry Linearity Accuracy 6. 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: SPECT imaging Dynamic scanning Planar imaging Dual phase scanning 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 patient. The absence of emission data. The absence of any material in the field of view (FOV). 8. All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT: Uniformity correction matrix SPECT phantom Multiple head registration (MHR) validation Center of rotation (COR) calibration 9. Well-counter calibration data of a positron emission tomography (PET) scanner are applied for: Attenuation correction. Energy window calibrations. Standardized uptake value (SUV) calculation. Image reconstruction. 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 - 2.0 + 1.7 + 2.0 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
