Abstract

An apparatus is provided to map blood vessels of a patient by infra-red illumination and further reproduction of the blood vessels on the body part of the patient. The apparatus comprises a flexible base having two parallel faces. The first face comprises a first matrix of infra-red light sources interleaved with a second matrix of infra-red light detectors adapted to detect the infra-red light reflected by the body from the infra-red light sources. The second face comprises a third matrix of visible light sources, each of said sources being back to back with an associated infra-red detector of the first face. The light of each visible light source is modulated by the quantity of the infra-red light detected by the associated infra-red detector.
