A recently filed patent (Publication Number: US20240033381A1) outlines a method for fluorescent imaging of a subject, particularly in surgical areas. The method involves placing an illuminator with a similar emission band to a fluorescence imaging agent in the surgical area, administering the imaging agent, acquiring multiple images over time to track fluorescence intensity changes, and analyzing these images to detect variations in fluorescence. An exposure gain adjustment is then applied to the images based on the detected changes in fluorescence intensity. The patent also includes provisions for determining a perfusion slope, which directly indicates blood flow or leakage in the gastrointestinal tract, using the fluorescence imaging agent, such as indocyanine green.

Furthermore, the patent details a method for fluorescent imaging that includes placing a fluorescence reference in the surgical area, administering the imaging agent, capturing images over time, and analyzing them for changes in fluorescence. An exposure gain adjustment is made based on fluorescence changes detected from the fluorescence reference. Similar to the previous method, this approach also involves determining a perfusion slope to assess blood flow or leakage in the gastrointestinal tract using the fluorescence imaging agent, like indocyanine green. Additionally, an endoscopic camera system for fluorescent imaging is described, comprising a camera, camera controller, light source, and either a fluorescence illuminator or a fluorescence reference. The system is designed to acquire and analyze images of the subject's region of interest, adjust exposure gain based on fluorescence changes, and determine the perfusion slope of the fluorescence imaging agent, particularly indocyanine green.
