Paper Abstract

The characteristics of the thin silica based imagefiber have been investigated by evaluating the image thrown on the TV monitor. As a result, it has been found that the picture diameter of the imagefiber and the magnification of the eyepiece strongly relate to the image quality of the total system. On the basis of this result, the image system for the diagnosis of breast lesions with thte thin endoscope of only 0.4 mm diameter has been developed. And we have applied this system to 66 ducts and succeeded in observing 61 ducts (92.4%) and could get some clinical information, which would be useful to the early detection of cancer.
