Abstract

The discrete formulation of a coded-aperture image is recalled ; the principle of the numerical convolution is given and then we calculate a maximum value for the quadratic error. We show the advantages offered by a post-deconvolution filtering as well as by an iterative restoration of the slices. Finally we present the results we obtained by recons-tructing an object consisting of three slices which is a coarse model of the human heart.
