Imaging considerations in fiber optic endoscopy system for the gastrointestinal endoscopy

摘要

A theoretical model, which describes both the spatial distributions of photons in fluorescence endoscopic images for the detection of cancerous cells in the intra cavities of human body, specifically gastrointestinal path is presented in this paper. The design concept of the image probe, which was developed for collecting the low fluorescent emission using an excitation laser source and the imaging done through novel imaging lens scheme will be discussed with its advantages and limitations in comparison with the existing imaging schemes. Finally, a quantitative analysis done by varying the different parameters affecting the tissue fluorescence is discussed in this paper.
