[0031] [Configuration of Medical System According to First Embodiment]

[0032] figure 1 is a diagram showing an exemplary configuration of the medical system 1 according to the first embodiment of the present disclosure. The medical system 1 according to the first embodiment roughly includes at least a light source 11 (irradiation device), an image capture device 12 (image capture device), and an information processing device 13 . In addition, a display device 14 and the like may be further provided, if necessary. Each component is now described in detail.

[0033] (1) Light source

[0034] The light source 11 includes a first light source that irradiates specific light having a specific wavelength band to the image capturing target 2 and a second light source that irradiates white light to the image capturing target 2 . In the first embodiment, in one example, the special light is near-infrared light. Furthermore, the special light from the first light source and the wh...

no. 2 approach

[0076] A description is now given of the second embodiment. Descriptions of the same contents as those of the first embodiment will be appropriately omitted. In the first embodiment, the correction unit 1315 corrects the special light image based on the white light motion vector if the degree of correlation is equal to or higher than a predetermined threshold, and corrects the special light image based on the special light motion vector if the degree of correlation is less than the predetermined threshold. In the second embodiment, the correction unit 1315 calculates the third motion vector (MV3) by weighting and summing the special light motion vector (MV1) and the white light motion vector (MV2) according to the degree of correlation, and based on the third motion vector (MV3) corrects the special light image, as in Equation (1), as follows:

[0077] MV3=(1-α)×MV1+α×MV2...Formula (1)

[0078] here, Figure 10 is a graph showing the relationship between α and the degree of...

no. 3 approach

[0085] A description is now given of the third embodiment. Descriptions of the same contents as those of the first embodiment will be appropriately omitted. In the third embodiment, the correction unit 1315 performs motion compensation on the special light image based on the special light motion vector, and performs motion compensation on the white light image based on the white light motion vector. The correction unit 1315 generates a third image by weighting and summing the motion-compensated special-light image and the motion-compensated white-light image according to the degree of correlation. The correction unit 1315 corrects the special light image based on the third image. In this case, the way of weighting and summing is similar to the way of weighting and summing using formula (1) of the second embodiment. In other words, with a small degree of correlation, the ratio of motion-compensated special-light images increases, while with a large degree of correlation, the ...

Abstract

A medical system (1) is provided with: an irradiation means (11) that irradiates an imaging subject with electromagnetic waves; an imaging means (12) that images waves reflected from the imaging subject irradiated with the electromagnetic waves; an acquisition means (1311) that acquires first images based on a first wavelength band and acquires second images based on a second wavelength band thatdiffers from the first wavelength band; a first movement estimation means (1312) that calculates a first movement vector that is a movement vector between a plurality of the first images on the basisof a characteristic quantity in the first images; a second movement estimation means (1313) that calculates a second movement vector that is a movement vector between a plurality of the second imageson the basis of a characteristic quantity in the second images; a correlation calculation means (1314) that calculates the degree of correlation between the first movement vector and the second movement vector; and a correction means (1315) that corrects the first images on the basis of the degree of correlation.

Description

technical field [0001] The present disclosure relates to a medical system, an information processing device, and an information processing method. Background technique [0002] In the medical field, doctors and other medical personnel visually recognize lesions or other abnormalities in some cases by observing special light images obtained by irradiating special light having a specific wavelength band (for example, near-infrared light) to a living body. However, a special light image taken with special light having a narrower wavelength band than white light is generally darker than a white light image, and thus the influence caused by noise is relatively large. Therefore, in special light images, in one example, faint fluorescence deep within a living body will be masked by noise, causing it to be invisible in some cases. [0003] Therefore, special light images require noise reduction processing (hereinafter also referred to as "NR processing"). Furthermore, motion estim...
