Abstract :
An iterative algorithm is introduced which can compute and subtract the scatter bias. It is assumed that the scatter-free image is spatially bounded and anything outside the boundary is the result of recorded scattered photons. This information and the fact that the scatter distribution does not have appreciable high-frequency content are utilized
