We have been developing a portable X-ray Photography Preview System for past few years for the use in Home Medical Care. In order to develop a convenient and low cost Preview System we have focused on the penetrated ray of a conventional film /screen X-ray photography system. Previously we have reported, a system using CDS array that detect penetrated X-ray to prepare a real time preview image through intensifying screen. However, the electrical response and physical size of the CDS dominated the quality of an acceptable preview image. In this study we have therefore, proposed a detector with fiber optic instead of CDS. We have fabricated an array of 1, 273 fibers those arranged in order on a 35cm× 35cm cassette. As our proposed detector is integrated into the conventional X-ray film cassette, it neither generates additional exposure, nor increases additional workload for preparing a preview image. In order to demonstrate the quality of preview image and adequateness of the system, we have experimented applying X-ray. We have succeeded to get a preview image suggesting higher possibility of clinical use as a detector for a real time preview system.
