“…Other detector factors such as energy resolution and spatial resolution are not considered in this study and an otherwise 'perfect' camera was assumed. Exact interaction positions and energy depositions in the two detectors for successful photon events were saved to output data files and images of the point source were reconstructed from the simulated data using a simple back projection algorithm [15].…”

“…Note that for these simulations the scatterer was still assumed perfect. The simulated energy and position data were then processed on an event basis using a listmode back-projection algorithm whose ellipse equation was derived using the steps provided by [21]. The algorithm analyzed each parameter of the event data to reconstruct a source image.…”
