I am interested in modelling background noise in my SPECT images and I have included the lines below in my macro. Is there a way to include a random spatial distribution for the noise? I expected that the background noise would appear randomly throughout the
crystal but all of the counts associated with background noise are located directly in the center of my crystal.<br>
