Method, system and program product for tomographic backprojection using multi-color rendering engine

摘要

Method, system and program product are provided implementing a technique for backprojecting an image from a projection data set. The technique includes splitting the projection data set into a plurality of multi-channel textures, with each multi-channel texture corresponding to a predetermined number of color channels of a multi-color rendering engine. The multi-color rendering engine is employed to simultaneously render the split projection data set and obtain intermediate results for each color channel. The intermediate results of each color channel are then accumulated to generate separate rendered images, wherein multiple images are simultaneously rendered from the projection data set using the separate color channels of the multi-color rendering engine.
