Paper Abstract

A computer program to simulate the three dimensional impulse response of a convergent focus rectangular tube collimator system has been developed. The simulation is done by a deterministic algorithm that models geometric acceptance of photons, photon penetration of the septa, and single scatter interactions in the collimator walls. Output from the simulator is used as a basis set for the impulse response of a multiple detector SPECT system. The basis set is used by fitting procedures that estimate the impulse response of the Donner SPECT system (12 angles, 12x 128 detector positions per angle) from noisy measurements of a point source. These impulse response estimates are used to determine the weighting matrix of new emission reconstruction algorithms.
