A Monte Carlo Simulation Study of Optimization for Collimator in a Pixelated SPECT Camera

A gamma camera is a device in which the gamma radiation emitted by radiopharmaceuticals is detected, and an image is formed. The image quality depends on the extent to which the rays reach the detector in a specific aligned direction. One of the crucial elements of a gamma camera is a collimator. Collimators are generally characterized by their imaging properties, spatial resolution, and sensitivity. In a single photon emission computed tomography (SPECT) camera, the spatial resolution primarily depends on the geometry of the collimator design.
