Paper Abstract

This paper describes a new scheme of generating a sharply focused x-ray beam for obtaining radiopacity information at discretely sampled points on an object, optionally combined with a multiple detector system for further improving the radiopacity contrast. Zoom capabilities are provided for clinical diagnosis and other purposes. It is an application and further specialization of the x-ray microbeam system that was invented by one of the authors and implemented at the University of Tokyo for the purpose of acquiring data on articulatory movements [Fujimura et al., 1973]. A generalization of the scheme into a fan beam (rather than a pencil-beam) system, by the use of a slit in place of the pinhole, in combination with arrays of detectors, is also described, as well as a multiple pinhole system using more than one pencil beam simultaneously. Specially designed x-ray generating targets are proposed for these systems.
