Abstract
A method and apparatus for correcting scattering in SPECT I-123 imaging. The method generally includes: accessing list mode data for a plurality of pixels corresponding to a first SPECT I-123 image generated using a gamma camera; generating a raw energy spectrum for at least some of the pixels utilizing the acquired list mode data; acquiring a gamma camera model corresponding to the gamma camera; utilizing the gamma camera model and an iterative algorithm to apply a first scattering correction to the raw energy spectrum; utilizing a Compton window to apply a second scattering correction to the raw energy spectrum; and generating a correction table with the corrected raw energy spectrum.
