Abstract： |
The invention relates to multi-access near infrared light diffusion imaging system of brain functional research, which belongs to medical equipment technological field, comprising of near infrared light laser source, multi-access optical fiber switcher, reflected sensing head with multi-light source and multi-detector, electro optical signal collecting and magnifying circuit system, computer with data collection card and program or controlling signal collection and imaging. The sensing head is reflected sensing head with multi- light source and multi-detector, with a rectangular slice made of soft material as substrate; the light source and detector arrange according to the way of rectangular array, each detector light source is embedded in the central point of rectangular area formed by four light sources or switcher adjacent. Besides, the invention uses the way of contrast imaging, eliminating the effect caused by mismatching between the access, and it doesn't bring hurt, pocketable and stable, also, it can realize real time dynamic imaging which is easier to understand, suitable for clinical application. |
