METHOD OF REDUCTION OF SEPTAL SHADOWS FOR THICK SEPTA COLLIMATORS

摘要

Disclosed herein is a method for removing septal shadows from thick septa collimator images, comprising disposing a line radiation source in a first orientation with respect to an imaging detector; disposing a thick septa collimator between the line radiation source and the imaging detector; where the collimator and the detector move in unison with one another; obtaining a plurality of a line images, where each line image is taken at a different location of the line radiation source with respect to the thick septa collimator; wherein each different location of the line radiation source is along a first linear direction; and relocating the plurality of the line images so obtained to a common location; and summing the images to reduce the septal shadow effects.
