Exam 16: Positron Emission Tomographycomputed Tomography Scanners

Which of the following can reduce noise in the final reconstructed positron emission tomography images? I. use of image segmentation II. use of a single photon rather than a positron-emitting source III. use a special noise filter

An atom that has too many protons or too many neutrons or they are configured in such a way so as to render the nucleus unstable, is said to be a(n):

All of the following are limitations of positron emission tomography/computed tomography technology except:

All of the following are scintillating materials used in PET detectors except:

Sodium iodide and bismuth germinate are newer scintillating materials that have reasonably high detection efficiency.
