Micro-Scanning Endoscope with Diagnostic and Enhanced Resolution Attributes. (MEDEA)

The enhancement of endoscopic visualization systems which is important prerequisite in minimally invasive interventions is directed to future endoscope units which offer improved resolution, increased miniaturization, higher automation, better image processing, advanced and automated diagnostic imaging features. These goals correspond to the main objectives of the present (MEDEA) project. The main work content of the project is the development of a microscaaner module settled at the front end of an endoscope for medical or biomedical applications. Secondarily, system-based improvements and technical-type applications of this endoscopic device will be also considered. The module in question will be based on the principle of confocal scanning techniques combined with electronic control and image processing of the received output. For examinations of spectroscopic nature, three diode laser beams (of different colors) will be scanned over the target tissue by means of micro-optic components and a pivoting silicon-mirror system in the above module. By means of suitable electronics and software, the detection and measurement of the re-emitted light will be synchronized to the mirror movements and will be used for a 3-color imaging of the observed objects/tissues after appropriate signal processing and handling. The possibility of installing a computer-based expert system at the output will also be investigated. The principal clinical benefits expected from the proposed system are the possibility of detailed therapeutic intervention with simultaneous on-line diagnostics, and the increased accessibility of remote and small-size body regions, as a result of the miniaturization of the device, for early diagnosis and local cancer treatment. Finally, extramedical applications could also be possible in fields such as technical endoscopy, display techniques, information technology and other related topics.
