Abstract
A method of reducing artifacts caused by generation of unwanted photons by scattering (e.g., Compton scattered photons) in which a detected event is spatially convoluted with a spatial filter function. The filter function has a distribution of weights within the filter function that is dependent on the energy of the event for a same primary event energy.
