Abstract :
This paper presents a novel convolutional method called convolution reverse-projection (CRP) for reconstructing objects from their X-ray projections. CRP has a significant edge over the popular convolution back-projection (CBP) method, because it uses a more accurate back-projection method. Reverse-projection avoids the interpolation and compensates for the differences in ray-density in the reconstruction region
