Abstract

In order to provide an optical measurement system and an optical measurement method which is suitable for optically measuring a body to be inspected and easily obtaining an image of a desired item based on information obtained by the measurement, an optical measurement method comprising an initial display process for selectively instructing any one of selection of optical measurement, analysis of said optical measurement result and completion of a program (S1); a process for inputting items of condition including a measurement mode (S2); a process for displaying a light irradiation position and a light detection position and a state expressing measurement position relationship together with said mode (S4); a process for instructing to form a file for storing said optical measurement result; a process for instructing a measurement condition to detect light signals from the inside of a body to be inspected which is irradiated by a multi-wavelength multi-channel (S10); and a process for displaying said signals for each channel detected according to said instructed result (S11).

Claims

1. An optical measurement system comprising:

a plurality of light sources for irradiating light on a biological body;

a plurality of light detectors for detecting light which is irradiated from said light sources and propagate through said biological body;

a computer for calculating the concentration of oxygenated hemoglobin and deoxygenated hemoglobin; and

a display for displaying a calculated results of said computer;

wherein said display displays a window for showing correspondence between a measuring channels and a channels of A/D converter, where which measuring channels to use for measuring or which measuring channels to display may be specified.

2. An optical measurement system according to claim 1, wherein

said window has a part for changing a dynamic range of said A/D converter, or a part for changing a gain of a lock-in amplifier.

3. An optical measurement system according to claim 1, wherein

said window has a part for selecting whether to acquire a signal of another measurement instrument.
