Abstract
A brief description of the standard rotating tomographic collimator and a new magnifying tomographic collimator is given. The geometry of the apparatus is quantitatively described and the modulation transfer characteristics for the standard apparatus and for various configurations of the proposed system using various source frequencies and planar depths are calculated. The smearing function for a line source is also calculated. It is shown that planar depth resolution can be improved at the expense of decreasing geometric efficiency. The advantages of using a magnifying collimator in the tomographic scheme are discussed.
