Description

Single-photon emission computed tomography (SPECT) is a nuclear-medicine imaging technique that has been shown to provide clinically useful images of radionuclide distributions within the body. However, the problem of quantitative determination of tomographic activity images from a projection data set is hindered by attenuation and scatter within the body. The incorporation of Compton scattering into the SPECT model is considered here. The mathematical model is built from first principles of photon interaction within the body and is then studied to determine its validity. The model leads naturally to a reconstruction procedure that compensates for attenuation as well as eliminates scatter
