Abstract :
In this paper, we present a new algorithm based on back projection and radon transform, which improves reconstructed image. In other words, after accepting image from BP algorithm, we use direct radon transform to enhance obtained image. By applying this method in biomedical imaging we can reconstruct image without using filtered BP. in particular new method can replace FBP. Theoretical analysis and simulation results which are presented prove the advantages of the new algorithm.
