1. A method, comprising:
acquiring imaging data corresponding to a plurality of divergent X-rays;
assigning a single functional form to the plurality of divergent X-rays;
determining, via a homographic transform, weights of interaction between a plurality of distribution samples and a plurality of X-ray detector bins based on the single functional form;
reconstructing an image based on the weights of interaction; and
sampling the single functional form to obtain a desired level of precision, wherein a set of basis functions are selected for a set of homographic transforms based on the desired level of precision, and wherein a size of the set of basis functions is increased to correspondingly increase the level of precision.
