Abstract
The sampling requirements of tomographic projection data are determined by the set of frequencies occupied by the Fourier transform of the projection data. This region of essential support has been analyzed for various 2-D geometries. The general case of 3-D cone beam projections, using a 2-D detector array, is mainly unexplored. In this paper, we consider the 3-D circular cone-beam (CCB) scan. An analysis of the essential support of CCB projection data provides the sampling requirements for detector spacing, row spacing, and projection count (views).
