Abstract

This paper describes a high resolution x-ray imaging device, which is under development at the University of Arizona. It is sponsored by NIH for application in coronary angiography, but has also application in other x-ray imaging fields requi ing high spatial resolution, such as mammography and nondestructive tasting. It consists of a 6" diameter external modular sensor, coupled fiber optically to the input of a 6" proximity focussed image intensifier. The intensifier's output is coupled via 6 fiber optic tapers to 6 CCD's for readout. The tapers are joined at the large end to form a 6" by 6" coplanar fiber optic taper assembly. The electronics is designed to form a composite image out of the 6 individual images provided by the 6 CCD's and display the image in full resolution (1152 x 1152) on a high resolution physicians review console. The paper discusses the design considerations, the features, the major problems and some preliminary results.
