Unformatted text preview: b) Human PET image c) Human SPECT image Describe each image, why it was taken and what it shows, and which radionuclide/tracer was used in what form and why. 5) In principle, in PET the site of gamma particle pair generation can be further localized to a specific point along the line which the gammas travel based on the time difference of their arrivals at the detectors. Do a web or library search and report at least one recent research or commercial attempt to exploit this information. What practical/engineering challenge(s) are there with this method? 6) What is the advantage of operating (i.e. choice of voltage bias) an ionization tube (e.g. a Geiger Muller tube) in the “Geiger region?” 7) Assume that a particular isotope is a gamma emitter with gamma energy 160 keV. Sketch the Pulse Height Analyzer spectrum of a sample of this source including scattered radiation....
