Method for diagnosing proliferation regions and device for realizing the same

摘要

Non-invasive, contract-free method for the diagnostics of the proliferation areas of biological tissue and their localization zones n vivo in a live organism on the basis of visualizing the fluorescence of endogenous porphyrins and a device for implementing this method. Tissue is irradiated with low intensity monochrome radiation in the wave length band of 630 to 645 nm and the fluorescent image is recorded within the band of 650 to 730 nm. Recording is carried out in one or several cycles, the brightness values of the corresponding points in the images are averaged for all recording cycles, the significant brightness range of the averaged image is established and broadened by way of re-calculation with regard to the entire dynamic range of the display device. A color reference image of the tissue and auxiliary images are recorded additionally at the excitation wave length and at the fluorescence wave length with illumination from the corresponding sources, and the fluorescent images of the natural proliferation areas of the same patient and a fluorescing test object are recorded. The device for implementing this method contains an additional laboratory premises lighting source.
