GATE Simulations of Human and Small Animal PET for Determination of Scatter Fraction as a Function of Object Size

In 2D-mode positron emission tomography (PET), scatter is either compensated by approximate methods based on the existing emission data or ignored altogether as the magnitude of the scatter fraction (SF) is on the order of 10%-20%. In clinical PET studies, however, attenuation and sophisticated scatter correction methods are required along with CT or… (More)
