Paper Abstract

We are investigating a prototype x-ray imaging system in which a scintillating fiberoptic glass plate and/or a fluorescent screen is fiberoptically coupled to a 2048 x 2048 CCD array (Tektronix). The imaging system includes a fiberoptic minifier to increase the imaging field of view to a clinically usable one. The system also allows for cooling of the CCD to reduce the effect of dark noise on image quality and the use of single-stage light amplification to act as a shutter and to provide gain control. Images are software corrected for dark current, individual pixel gain, and geometric distortion. Preliminary results indicate that high quality x-ray imaging can be obtained using this methodology. This paper describes design concepts and configuration of the system as well as characterizations of the initial x-ray images acquired with the camera.
