Multicenter near-infrared diffuseness imaging system for cerebral function image

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.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to the design of an imaging system for brain function research. Background technique [0002] At present, the main equipment for brain function research is PET (Positron Tomography) and fMRI (Functional Magnetic Resonance Imaging). Both devices are damaging and not suitable for use in certain situations (such as in infants, pregnant women, or acupuncture on acupuncture points on the brain, etc.). Both PET imaging and MRI imaging are expensive, costly, and inconvenient to use. In contrast, although the imaging resolution of near-infrared imaging equipment is not as good as that of PET and fMRI, its cost is low, and it is relatively portable, so it can be more conveniently applied to various occasions. [0003] Near-infrared spectroscopy mainly utilizes the absorption and scattering properties of human tissues to near-infrared light. Blood in tissues is the main absorber ...

AI Technical Summary

Problems solved by technology

The data obtained in this way will greatly degrade the results of tomographic images

In addition, this system has relatively high requirements for the design of the probe. In order to improve the accuracy of the measurement, it is usually required that the light source and the detector are vertically attached to the surface of the measured object. However, due to the irregular shape and size of the human brain, the design A probe that can be widely used in clinical trials is very difficult

Therefore, this system is not suitable for clinical brain function research experiments
