Abstract
A previously reported semi-analytical expression for calculating the point spread function (PSF) of singly scattered x-ray radiation is shown to exhibit excellent correspondence with Monte Carlo-determined PSFs where only single scatter was allowed to occur. A neural network was trained to transform the semi-analytic single scatter PSF to the PSF for both single and multiple scatter. Using comparisons between the semi-analytic/neural network generated and the Monte Carlo generated PSFs, excellent agreement was found. The technique proposed here appears to be an accurate method for rapidly calculating the scatter PSF from three physical parameters, and such a formulism should be useful in algorithms designed to correct for scattered radiation effects in digital images.
