Abstract
The early detection of cancer offers a higher possibility of a cure by laparoscopy or surgery. For proper treatment, the early detection of lesions and an accurate diagnosis are necessary. Endoscope quality has improved as the basis of endoscopic diagnosis.
Over 20 years have passed since the development of the videoscope. Diagnostic imaging today has been further improved by increased resolution, as with HDTV, applying enhancement technology to identify mucosa appearance an subtle color changes, and using magnifying scopes of improved operability.
The absorption and scattering characteristics of tissues differ according to the examination wavelength, resulting in major differences in the information obtained. Using a videoscope that mounts a CCD as a light sensor and selecting a wavelength that is suited to the objective and the characteristics of the tissue, new diagnostic information can be obtained. For this reason, further developments of the endoscope are hoped for.
This chapter looks at the technological developments desired by the many doctors participating in EFJ, and discusses the future possibilities of technological developments from the perspective of a developer.
