METHOD OF DIAGNOSING MALIGNANT TUMORS IN STOMACH AND LUNGS Russian patent published in 1994 - IPC

Abstract RU 2012243 C1

FIELD: medicine, in particular, oncology. SUBSTANCE: new method prescribes inserting optical fiber catheter associated with multi-channel optical spectrum analyzer via endoscope into organ to be studied, allowing laser rays to pass through this catheter, and determining intensity of fluorescence. Radiation is spectrum red band. Intensity of dispersed laser component and spectrum of fluorescence of portion of tissue under investigation and normal mucous membrane is measured in range of 600 to 800 nm. Degree of diagnostic contrast is found by using formula presented in specification. EFFECT: higher accuracy of diagnosis. 1 tbl
