| titleOfInvention | Multi-wave endoscopic system and image processing method using it |
| abstract | FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment, specifically to means of visualizing an observation site using an endoscopic system. Multi-wave endoscopic system for imaging an observation portion marked with fluorescent materials having different colors, comprises a visualization unit configured to obtain image data by polarization of incident light reflected from the viewing portion, in a first direction and a second direction perpendicular to the first direction, dividing the incident light spectrum region polarized in the first direction and the second direction, to a plurality of spectral channels and measuring light intensity for each of the spectral channels, and a computing unit configured to store one fluorescence spectrum extracted from the sample image data obtained by single processing of the viewing portion of each of the fluorescent materials, and configured to separate and output image data obtained in the imaging unit, using one fluorescence spectrum such that each of the fluorescent materials is displayed separately, wherein the computing unit is configured to store an unprocessed fluorescence spectrum extracted from the raw image data obtained by viewing an observation portion not marked with fluorescent materials, and wherein the computing unit is configured to perform a correction to exclude the autofluorescence component contained in the image data obtained in the imaging unit using the untreated fluorescence spectrum. In the second embodiment, the system comprises a beam splitter configured to polarize the incident light reflected from the viewing portion, in a first direction and a second direction perpendicular to the first direction, a first zone filter located on the path of the light beam branched in a first direction and configured to transmit a light beam within a predetermined spectral range, a second zonal filter located on the path of the light beam branched in the second direction, and configured to transmit the light beam within the predetermined spectral range, a first zonal chamber configured to measure the intensity of the light beam passing through the first zone filter, a second zonal chamber configured to measure the intensity of the light beam passing through the second zone filter, and a computing unit configured to divide and output image data obtained using intensity of the light beam passing through the first zone filter, and the light beam intensity passing through the second zone filter, such that each of the fluorescent materials is displayed separately, wherein the computing unit is configured to store an unprocessed fluorescence spectrum extracted from the raw image data obtained by viewing an observation portion not marked with fluorescent materials, and performing the correction to exclude the autofluorescence component contained in the image data using the untreated fluorescence spectrum. A method of processing images using a multi-wave endoscopic system having a visualization unit and a computing unit, comprising steps of emitting light to an observation portion, which is marked with fluorescent materials having different colors, using a visualization unit, receiving image data by receiving light reflected from the viewing portion using the imaging unit, dividing the image data in such a way that only one of the fluorescent materials is displayed using the computing unit, and outputting the separated image data corresponding to the wavelength band using the computing unit, extracting the raw fluorescence spectrum from the raw image data obtained by visualizing the observation portion not marked with fluorescent materials, and correcting to exclude the autofluorescence component contained in the image data using the non-processed fluorescence spectrum using the computing unit.EFFECT: use of inventions makes it possible to increase accuracy of detecting the area of disease occurrence and to reduce the number of false positive determinations.7 cl, 1 tbl, 10 dwg |
