Abstract

In a recent paper in this journal by Kesidis and Papamarkos ''A new method for the exact reconstruction of any gray-scale image from its projections is proposed.'' In this note we point out that this method is a special case of a well-known approach (peeling) and that it can produce exact reconstructions only under assumptions that are not realistic for practical methods of data collection. Further, we point out that some statements made in the paper regarding disadvantages of the algebraic reconstruction techniques (ART) as compared to the method of the paper are false.
