  • Abstract
  • Look Inside

 The electronic endoscope differs from the fiberoptic endoscope in that it contains a small light-sensitive CCD chip which is attached to the tip of the endoscope. The image detected by the CCD chip is passed in the form of an electronic signal through the endoscope to the video processor, which charges the signal into a form capable of being visualized on the TV monitor.

 Thus, the electronic endoscope has great possibilities of clinical applications such as computor analysis of the endoscopic image, which has not been obtainable on the fiberoptic endoscope. At present, the electronic endoscope has many problems such as the number of pixels and poor latitudes, however, the image provided by this system is superior to that obtained by a fiberoptic endoscope in resolution of the detail. It is expected that remarkable development of diagnosability will be provided by the electronic endoscopy in association with an improvement of CCD and TV monitor.

 Explanation was given on these subjects above mentioned, and some cases were presented.
