A method and apparatus for imaging features of a CBD in a patient introduces a fluorescent contrast agent into the CBD. A light source transmits both a visible light and a fluorescent light into a patient's abdominal cavity via the laparoscope. Cameras attached to or integrated into the laparoscope detect visible light images and fluorescent emission light images. The visible light image and fluorescent image signals are processed to combine the fluorescent emission light image signals and visible image signals into a single display signal. The system adjusts the display characteristics, such as color, of the fluorescent emission light image so it contrasts well with the visual light image so the surgeon can easily distinguish between the two images. The display signal is sent to a video monitor where the surgeon views the visible light image and the fluorescent image as a single overlaid image.
