Abstract

A safety housing, into which an infrared laser light source is integrated together with the CCD camera, forms a compact unit for the determination of tissue perfusion. Rays from the infrared laser light source radiate the area of operation and indocyanin green, previously injected intravenously into the patient, is excited to fluorescence by the radiation, which is detected by the CCD camera.
