摘要:
A fluorescence endoscopy video system includes a multimode light source for producing white light, fluorescence excitation light, or fluorescence excitation light with a reference reflectance light. An endoscope directs light to illuminate a tissue sample and collects reflected light or fluorescence light produced by the tissue. A camera includes a high sensitivity color image sensor having a plurality of pixel elements. Each of the pixel elements has an integrated filter configured to block reflected excitation light from reaching the pixel elements and allow fluorescence and reflectance light to reach the pixel elements. A processor receives image signals from the image sensor, combines image signals from a first group of pixel elements to form a first image formed by fluorescence light, and combines image signals from a second group of pixel elements to form a second image formed by reflectance light. A video monitor simultaneously superimposes the first and second images.
