Popis:	Three-dimensional Computed Tomography (CT) with cone-beam geometry will take the place of a conventional CT because 3-D CT is superior to conventional CTs in terms of both data acquisition time and spatial resolution, particularly along the rotation axis. The small bone structures are reconstructed using magnified projections of the region of interest. This paper describes the solution for some problems in practical use. Experimental results show 3-D CT will be feasible.© (1991) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
