heal.abstract SPECT images suffer from low contrast as a result of photons scatter. The standard method for excluding scatter component in pixelized scintillators is the application of an energy window around the central photopeak channel of each crystal cell, but small angle scattered photons still appear in the photopeak window and they are included in the reconstructed images. In this work we have assessed three subtraction techniques that use a different approach in order to calculate the scatter component and subtract it from the photopeak image: The Dual Energy Window Subtraction Technique (DEWST) the Convolution Subtraction Technique (CST) and a Deconvolution Technique (DT). All these techniques are compared to the standard method. The experimental results showed the superiority of DT, as a scatter correction technique. © 2005 IEEE. en
