摘要：
Algebraic Reconstruction Technique (ART) is a method for reconstructing images from projections. It is widely used in applications such as Computed Tomography (CT). The algorithm requires fewer views, and hence less radiation, to produce a satisfactory image. However,, the approach is not widely used due to the computational intensive nature of the problem. In this paper we design and develop a Parallel ART (PART) algorithm and study its performance on a network of workstations using the Message Passing Interface(MPI).
