Abstract :
Radon transform is a widespread technique in image analysis. It is also the basic mathematical model for computer tomography. But Divergent Beam transform is a more suitable mathematical model for data acquisition. This paper reviews the mathematical description of the two transform and presents an algorithm for conversion from Divergent beam transform data to Radon Transform data. This makes it possible to use the algorithm based on Radon transform for the Divergent Beam transform.
