A Novel Method for Projection Based on Bresenham Like Algorithm

摘要

Radon Transform and Divergent beam transform both are widely used projection methods in the field of computer tomography and signal processing. In this paper we reviewed the commonly use method for implement the projection method and then give a novel method for implement the projection, which is especially suitable for divergent beam transform in 2D. The method is based on the bresenham like line or circle drawing algorithm, so it is easy to implement and have a low computational complexity.
