A comparison of four pre-processing attenuation correction methods for single photon emission computed tomography

The accurate quantitation of Single Photon Emission Computed Tomography (SPECT)images is restricted due to the attention of gamma photos in patient's body. A number of approximate attenuation correction methods have been proposed to date. In this work, an attempt is made to implement four exist...
