NMTCB PET certification Review questions with correct answers

A. is correct. The computer has made SPECT imaging possible in both coordinating the collection of data and in performing the complex calculations necessary for reconstruction in image production and analysis. Answer 3.001 All SPECT imaging devices are computer controlled for both data acquisition and data analysis. A. true B. false D. is correct. Volume elements, or voxels, represent the pixel with the added dimension of depth, or volume. Answer 3.002 Pixels are picture elements of the image matrix that represent individual location counts in the x and y directions. In SPECT imaging, adding depth makes pixels become: A. matrices B. point sources C. vertical elements D. volume elements B. is correct. A composite of the ray sums is the basis for back projection reconstruction. It may be defined as an even projection along the path of the acquired angle. Answer 3.003 In SPECT imaging, parallel-hole collimators are used to insure that the detectors see only the photons along a narrow band that extends from the detector to organ in the radius of rotation. This narrow band is called a: A. column
