ABSTRACT:
A method of obtaining scatter-corrected images from a nuclear imaging apparatus such as a gamma-ray camera involves the use of a calibration step which measures the energy spectrum response of the apparatus to unscattered gamma-ray events as a function of spatial location, and a correction step which deconvolves the unscattered distribution from a distribution measured in the presence of scatter by using the calculated calibration response function. The method eliminates the necessity of performing a spatially dependent energy correction for detected radiation image events.
