Abstract
The quality of single-photon emission computed tomography (SPECT) imaging is hampered by scatter, attenuation and collimator blurring, and Especially, efficient scatter correction has proved to be difficult to achieve. Objective: The objective of this article was to assess the accuracy of three well-known methods of scatter correction in comparison to monte-carlo studies. methods: Different homogenous phantoms with non-uniform activity distributions and attenuation maps were simulated by SimSET then DEW, TEW and Klein-Nishina Scatter correctoin methods applied on different projections of SPECT for scatter estimation. the result of scatter estimation by these three methods compare to scatter projections simulated. Results: Klein-Nishina scatter estimation & TEW has the least differences to simulated scatter.
