Abstract

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 existing pre-processing (arithmetic mean-based and geometric mean based) attenuation correction methods, and to test via gathering the data by scanning a cylindrical phantom over 360 degrees. The phantom was filled with water and Tc-99m solution was uniformly distributed. An acrylic block with holes and various sizes at different interior locations with respects to wall of phantom simulating "hot" regions was used.
