Abstract
A mathematical algorithm for 3-dimensional reconstructions in the positron camera is described. Fourier techniques were adapted for use in analyzing the data from cameras with limited detector configuration. Noise instabilities from random fluctuations in the data are discussed and treated. The technique is tested on a computer-generated phantom and the results are presented. Ways of incorporating the effects of Compton scattering and detector response into the algorithm are discussed. The method seems feasible and practical for obtaining accurate reconstructions.Keywords
