Abstract

A novel approach for implementing tomographic reconstruction algorithms using optoelectronic CCD (charge coupled device) structures is described. The approach employs the algebraic reconstruction technique (ART). The proposed method overcomes the problems of poor reconstruction results and implementation difficulties traditionally associated with ART. The optoelectronic approach described offers significant advantages over existing electronic methods both in terms of computational speed and quality of reconstruction
