Optical bioinstrumentation for living body

An optical bioinstrumentation for living body comprising:

• a probe that includes an irradiator which irradiates light to a subject and a detector which detects transilluminated light having been irradiated from the irradiator and having been propagated through the subject, and that is mountable on the subject;
• a computing unit that calculates a concentration of metabolite in the subject according to a signal detected by the detector;
• a position sensor that detects a three-dimensional position of the probe;
• and
• a display unit that displays an indicator indicating the concentration of metabolite calculated by the computing unit;
• and
• a memory unit in which measurement data is saved, wherein:
• the computing unit is further configured to determine a position on the subject at which the probe should be disposed where the positions on the subject of the irradiator and the detector are positions at which normals to the positions on the subject of the irradiator and the detector intersect an area of interest of an anatomical image of the subject or a brain functional image thereof,
• further wherein the display unit displays representations expressing the determined positions on the subject of the irradiator and the detector superimposed on the anatomical image of the subject or the brain functional image.

An optical bioinstrumentation for living body comprising:

• a probe that includes a plurality of irradiators which irradiate light to a subject and a plurality of detectors which detect transilluminated light having been irradiated from the irradiators and having been propagated through the subject, and that is mountable on the subject;
• a computing unit that calculates a concentration of metabolite in the subject according to a signal detected by the detectors;
• a display unit that displays an indicator indicating the concentration of metabolite calculated by the computing unit;
• and
• a memory unit in which measurement data is saved, wherein:
• a substantial midpoint between the irradiators and the detectors is regarded as a sampling point;
• representations expressing the positions on the subject of the irradiators and the detectors and representations expressing positions on the subject at which the irradiators and the detectors are disposed at the time of previous measurement are displayed on the display unit while being superimposed on the anatomical image of the subject or a brain functional image thereof;
• when the distance between a predetermined region to be measured, which is expressed by a representation contained in the anatomical image or the brain functional image, and the position of the sampling point falls within a predetermined range, or when positions on the subject at which the irradiators and the detectors are disposed at the time of previous measurement and the current positions of the irradiators and the detectors fall within a predetermined range, an alarm is given;
• and
• the positions on the subject of the irradiators and the detectors superimposed on an anatomical image of the subject or the brain functional image thereof, are positions at which normals to the positions on the subject of the irradiators and the detectors intersect a section of the anatomical image of the subject or the brain functional image thereof which includes an area of interest internal to the subject.
