Abstract

At many medical diagnostic problems it is desirable to be able to detect and visualize different blood vessels and blood vessel changes (in e.g. blood vascular wall). This desire has been solved through using a light source (1), a photodetector (2), a motor system (5) for measurement of different spots and a specific combination of different measurement geometries (8, 10 and 11) whereby you may record reflected radiant power from different structures in the tissue (7), whereupon you may monitor blood vessels (9) through a picture on a monitor (4). After identification it is also possible with this equipment to monitor different physiologic parameters.
