Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….
Determine the maximum scatter angle such that the photons will be within a 10% pulse height window.
You will be imaging a radioactive source using an Anger camera.
(a) Sketch and label the pulse height spectrum. Make the photopeak at 180 AU (for 140 keV photons).
(b) Determine the maximum scatter angle such that the photons will be within a 10% pulse height window.
For parts (c) and (d), assume the PMT arrangement and corresponding pulse heights shown in Figure P8.4.
(c) Compute the Z-pulse.
(d) Computer the position (X,Y) of the event.
(e) What are the causes of event localization error?
