LIGHT MEASUREMENT DEVICE FOR LIVING BODY, ULTRASONIC DIAGNOSTIC DEVICE AND LIGHT MEASUREMENT METHOD FOR LIVING BODY

摘要

PROBLEM TO BE SOLVED: To improve ultrasonic probe position guide in ultrasonic imaging utilizing light measurement for living body.;SOLUTION: A light measurement device for living body includes a light irradiation unit, a plurality of light detection units, an image acquisition unit, and a calculation unit. The light irradiation unit is brought into contact with the surface of a living body and emits light to the surface substantially vertically. The plurality of light detection units are light detection units which are arranged at mutually different positions on the periphery of the light irradiation unit, at least one of which is inclined at a prescribed inclination angle with respect to the central axis of the light irradiation unit, and which detect the intensity of the light emitted from the light irradiation unit and diffused and reflected in the living body. The image acquisition unit acquires an image from detection means different from reflection light intensity distribution measurement of near infrared light with respect to the living body. The calculation unit calculates relative positions between the acquired image and light detection position from the signals of the plurality of light detection units and the image acquisition unit.;COPYRIGHT: (C)2015,JPO&INPIT
