In a method, a device and a computer program for determining the blood flow in a tissue or organ region, the fluorescence intensity of an exogenous chromophore is measured as a function of time in the tissue region to be examined and from this the permeation rate of the chromophore is calculated, from which the blood flow can be derived.

Method, device and computer program for determining the blood flow in a tissue or organ region

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.
