Abstract
This paper proposes an efficient GPU based parallel algorithm image reconstruction. It has been implemented on a system having a general purpose graphical processing unit (GPU), Nvidia graphics card GTX-275. Experimental results reveal that an image of size 256 × 256 with 90 projections can be reconstructed in real time with single iteration. The results enable us to use MART algorithm for online applications.
