Abstract:
1. A method of correcting scattering in SPECT I-123 imaging, the method comprising: a) accessing highly sampled photon energy data for a plurality of pixels corresponding to a first SPECT I-123 image generated using a gamma camera; b) generating, using a microprocessor, a raw energy spectrum for at least some of the pixels utilizing the acquired highly sampled photon energy data; c) acquiring a gamma camera model corresponding to the gamma camera; d) applying, using the microprocessor, a first scattering correction to the raw energy spectrum that utilizes the gamma camera model and an iterative algorithm given by e) applying, using the microprocessor, a second scattering correction to the raw energy spectrum utilizing a Compton window; and f) generating, using the microprocessor, a correction table with the corrected raw energy spectrum.
