Abstract: Improved fluoresced imaging (FI) endoscope devices and systems are provided to enhance use of endoscopes with FI and visible light capabilities. An endoscope device is provided for endoscopy imaging in a white light and a fluoresced light mode. A chromatic adjustment assembly, typically implemented with prisms, compensates for a chromatic focal difference between the white light image and the fluoresced light image caused by the dispersive properties of the optical materials or optical design employed in the construction of the optical channel. The assembly is placed optically between the most proximal rod lens of the endoscope and the focusing optics, typically at an internal telecentric image space, to improve the chromatic correction. The prism assembly directs incoming light with different spectral content along separate paths which compensate for chromatic aberration.

Abstract: The present disclosure is directed towards a video display system and an endoscopic system configured to provide the surgeon with an optimized video image based upon user preference. The video display system includes a first video image displaying a white light video of a surgical site. The first video image has a first predetermined area. A second video image is overlaid on the first video image. The second video image is displayed in a fluorescent light video. The second video image is centered on the surgical site and includes a second predetermined area. The second predetermined area is smaller than the first predetermined area so as to define a boundary of white light video. Thus, the video display system provides the surgeon with the ability to reference the location of the fluorescent light video with respect to anatomical features of the surgical site.

Abstract: Methods and systems are provided to generate metamerically matched illumination on a surgical site. The metamerically matched illumination may reduce or remove strobing effects associated with illumination devices during a surgery or surgical procedure. By metamerically matching illuminants in the illumination in combination with estimates of the human visual system, the illumination of the surgical site can visually appear to a user as a continuous white light, while maintaining distinct underlying spectra in the illumination. The light reflected by the surgical object may also be captured and metamerically matched, such that the reflected light appears as a single continuous color.

Abstract: The present invention relates to a method for producing adaptive lighting controls for an endoscope with multiple light emitting elements such as distinct light fibers, or distinct distal light emitting diodes (LEDs), etc. The amount of light delivered to the scene can be locally adjusted on a per-light basis to manage the dynamic range of the scene. For example highly reflective metallic tools many benefit from reduced light, while cavities may benefit from increased light projected into the lumen.

Responsive to an FOI being present in the frame but outside the ROI, a notification is created on the electronic display.
