COMPACT FLUORESCENCE ENDOSCOPY IMAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a fluorescence endoscopy video system.SOLUTION: A fluorescence endoscopy video system 50 includes a multimode light source 52 that produces light for a color imaging and fluorescence imaging modes. A system 50 includes a multimode camera 100 for color imaging and fluorescence imaging. Images obtained through the endoscope are optically divided and projected onto one or more image sensors by a fixed beam splitter in the camera 100. The fixed beam splitter eliminates the need for inserting a movable mirror into the light path between the endoscope and the image sensors. Image signals from the camera 100 are processed in a processor/controller 64 where a contrast enhancement function can be applied. The contrast enhancement function increases the color contrast between normal tissue and tissue suspicious for early cancer.
