Shimadzu Review 74[1・2] (2017.6)


Shimadzu Corporation released the new LIGHTVISION near-infrared imaging system in August 2016. The LIGHTVISION system provides high quality fluorescence images of Indocyanine Green (ICG), a fluorescence contrast agent, during operations. Surgeons can check the ICG fluorescence while viewing surrounding tissue on the triple picture display that includes visible, near-infrared, and composite images. Furthermore, the system enables them to use the images while the lights in the operating room are on. LIGHTVISION uses techniques such as efficient ICG excitation, high definition visualization, and high visibility composite images to enhance the imaging performance. This article describes the ICG fluorescence imaging techniques used in LIGHTVISION, based on an understanding of ICG characteristics.
