DISCRIMINATION METHOD OF TUMOR SITE, AND DISCRIMINATION DEVICE OF TUMOR SITE

摘要

PROBLEM TO BE SOLVED: To realize a method and a device which can perform discrimination of a tumor site more accurately than before, while taking into consideration influences exerted on the intensity of fluorescent light emitted from porphyrins due to a presence of a coloring agent for identification.SOLUTION: A method according to one embodiment of the present invention irradiates a specimen with light of a first wavelength included in a wavelength region overlapped with absorption spectrum of a coloring agent from among spectra of fluorescent light emitted by porphyrins after excitation, and includes: a step (a) of acquiring first image information showing an intensity distribution of light reflected by the specimen; a step (b) of exciting porphyrins by irradiating the specimen with excitation light; a step (c) of acquiring second image information showing the intensity distribution of a wavelength component of the first wavelength or the vicinity thereof from among fluorescent light emitted from porphyrins; a step (d) of generating third image information by standardization processing of the second image information on the basis of the first image information; and a step(e) of performing identification of a tumor site and a non-tumor site on the basis of the third image information.SELECTED DRAWING: Figure 4
