Abstract

This paper describes a high resolution x-ray imaging device which is being developed through NIH sponsorship by the University of Arizona. It consists of an external modular x-ray sensor, a proximity focussed image intensifier and six CCD's coupled to the output of the image intensifier via six fiber optic tapers. The tapers are joined at the large ends to form a coplanar fiber optic taper assembly. The spatial resolution is expected to be determined by the external sensor up to the Nyquist frequency of the CCD which is (after magnification by the tapers) 3.9 1p/mm. The intended application is coronary angiography.
