Abstract

This paper describes preliminary performance data of the components of a high resolution x-ray imaging device, under development at the University of Arizona through NIH sponsorship for application in coronary angiography. The system will consist 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.One taper has been delivered whith distortion of less than 1.2 %.One channel of the camera and display electronics is operational. The limiting resolution of a pilotsystem, consisting of a 40 mm Gen.II image intensifier, the fiber optic taper and a CCD is 3.9 1p/mm, the Nyquist frequency of the CCD magnified by the taper.
