Hybrid Endoscopes Applications for Internal Organs Oncology Diagnostics

Application of a new kind of endoscope has been proposed for the image of internal organs transmission. Image transmission is carried out not only by video camera but also some certain fragments of the image are transmitted by the image sensor based on fiber optics. This composition provides elimination of the information losses which are connected with three-colored principle of television image transmission. Additional spectral information increases the reliability of diagnoses made on the base of data presented by endoscope. The structural circuit of the proposed endoscope has been considered and discussed. The most common area of practical application of this endoscope is internal organs oncology diagnostics. In order to perform such diagnostics, some preliminary investigations are required because the reflection spectra of human tissues defeated by the cancer cells, are not yet known. Such hybrid endoscope can be used in gastroscopy, bronchoscopy, colonoscopy, laparoscopy, and all other similar areas. The principle of multispectral processing which is used in fiber-optics-based sensors provides obtaining of maximum possible spectral information in addition to high spatial resolution provided by RGB camera.
