Abstract

The authors have generated SRFs (scatter response functions) using the Monte Carlo simulation method and investigated the characteristics of the scattered radiation by fitting the SRFs with fitting functions. The parameters of the fitting functions were studied as a function of source position in a water-filled cylindrical phantom with circular cross section. The parametrization of the SRF provides insight into the spatial distribution of detected scattered radiation in SPECT (single-photon-emission computed tomography) and is useful in developing a method to compensate for its effects in order to improve both the quality and quantitative accuracy of SPECT images
