METHOD FOR ENDOSCOPIC FLUORESCENT EXAMINATION OF MALIGN SWELLINGS OF HOLLOW ORGANS Russian patent published in 1999 - IPC

Abstract RU 2129273 C1

FIELD: medicine, in particular, oncology. SUBSTANCE: method involves measuring ratio of integral intensity of fluorescent irradiation of tissue in spectral band of 625- 645 nm to superposition of spectra of natural (endogenous) and exogenous fluorescent irradiation of photosensitizer and to integral intensity of fluorescent irradiation in spectral band 550-570 nm (natural fluorescent irradiation of tissues). EFFECT: increased reliability of examination, decreased number of false positive signals. 5 ex
