Abstract

Image reconstructed from its projections or Computerized Tomography is very practical area of research, which is applicable in many other fields such as material testing imaging etc. In this work we give an inversion formula using discrete convolution back projection algorithm on discrete Radon transform, which makes it faster as interpolation is not required and results are comparable.
