Blood flow imaging system LIGHTVISION

laser speckle contrast

The near-infrared fluorescence imaging system irradiates near-infrared excitation light on an ICG (indocyanine green) contrast medium injected into the blood vessels, lymph ducts, or other areas. It is a system that allows the observation of blood flow and lymph flow under the tissue surface by imaging the near-infrared fluorescence. This method, called ICG fluorescence imaging, enables the simple and real time identification of lymphatic vessels and the confirmation of blood flow during surgery. It has been confirmed to be useful for the quick localization of sentinel lymph nodes and, tissue and organ perfusion. Expanding Clinical Applications Shimadzu’s LIGHTVISION system provides unprecedented clinical value by easily visualizing lymph and blood flow during surgery. Equipped with high definition sensors, the LIGHTVISION system displays detailed high definition images, which are especially useful for procedures requiring confirmation of blood flow through small blood vessels, such as in surgical flaps. Due to the large field of view, an image of a broad area, such as the abdomen, can be displayed on one screen, providing a quick overview when assessing blood flow through blood vessels in an abdominal flap or the gastric tube. Furthermore, the colors displayed in fluorescence images can be changed, which is especially helpful for identifying sentinel lymph nodes. Consequently, clinica l applications of LIGHTVISION are expanding into a wide variety of surgical procedures.
