Popis:	IN Single Photon Emission Computed Tomography (SPECT), attenuation and scatter introduce important artefacts in the reconstructed images biasing the diagnosis and the follow-up of the subject. Indeed, the presence of scatter results in a blurring and haziness of the observed projections, reduces reconstructed contrast and introduces significant uncertainty in quantification of the underlying activity distribution.
