Abstract

A new model for tracing the first-order Compton scatter was implemented in quantitative single photon emission computed tomography (SPECT) imaging based on the Klein-Nishina formula and Siddon method. This model was tested by simulation based on a thorax phantom derived from a patient chest computerized tomography (CT) image with a heart insert and a resolution kernel of a parallel-hole collimator. The simulation of 128 projections on an elliptical orbit from a 128² phantom array took approximately six hours on an HP/735 computer by tracing all pixels for both scatter and attenuation factors. The 3D simulation for 64 projections each with 64×32 bins from a 64²×32 phantom array was accomplished in less than four days.
