Deconvolution of Compton scatter in SPECT.

摘要: A deconvolution algorithm has been developed which compensates for Compton scattering in SPECT images. scatter is modeled as a convolution of the nonscattered projection data with an exponential function. Deconvolution total (scatter + nonscatter) yields compensated true projection. Using Monte Carlo methods, scattered and components image are simulated thus allowing comparison results direct nonscatter results. The quality compensation evaluated by comparing ratio to counts counts. This technique experimentally acquired well data.
