Abstract

This simulation study compares T1-201, cardiac SPECT images reconstructed from 180° and 360° emission projection data, using iterative reconstruction with non-uniform attenuation compensation. The images reconstructed with attenuation compensation are compared to each other and to images reconstructed without attenuation compensation. Using a mathematical phantom of the human thorax, Monte Carlo simulation is used to produce both 180° and 360° SPECT projection data for a 74 keV radionuclide (T1-201). Included in the simulation are the effects of non-uniform attenuation, detector response, and scatter.
