Abstract

In order to improve image quality of a high definition real- time I.I-DR system, we have developed an evaluation system using a 4M-CCD camera modifying a conventional system using a pick-up tube camera. An analysis of the conventional system shows that the image quality of total system is expected to be improved by changing camera. Basing on the analysis, we select a FFT type 4M-CCD camera for our purpose. From comparative evaluations of the 4M-CD DR system and the conventional system, the following results are obtained: (1) the image quality of high definition real-time DR is effectively improved by changing a conventional pick- up tube camera to a 4M-CCD camera; (2) the image quality of improved system is almost equal to that of S-F system, in case that the FOV of I.I is in 9 inch mode, which is most usual in GI-tract examination.
