Classification: A61B

Abstract:
An optical diagnosis system for an animal imaging, comprising:a bearing plate on which the animal may be arranged for treatment by an inert optical contrast medium having an activatable first marker and a non-activatable second marker; an excitation source for irradiating the animal and the inert optical contrast medium to initiate a fluorescent radiation in tissue of the animal; a detector system for detecting the resulting fluorescent radiation as radiated back from the tissue of the animal, wherein, the detector system is positioned above the bearing plate, the bearing plate is a radiation transparent window for a reference radiation, generated by a non-activatable second marker, for the detection of an initial concentration of the inert contrast medium in the tissue of the animal, and the second marker is one of a radioisotope marker and a fluorescent marker with an altered frequency related to the activatable first marker.
