Abstract
We used TV-endoscope manufactured by Toshiba-Machida. This electronic endoscope did not have fiber bundles for imaging but CCD (Charge Coupled Device) in its tip. We could take an endoscopic picture made of about hundred thousand pixels. As it was of high resolving power, we could observe the fine structures of the mucosal surface which was not obtained by the fiberscope for routine examination. At present its operating activity and the recording system of this TV-endoscope remain to be improved but it has great possibilities of clinical applications such as computor analysis of the endoscopic image and developing the new recording system by using the video disc.
