Device for acquiring multi-modal data of brain and application thereof

Abstract

The invention discloses a device for acquiring multi-modal data of the brain and the application of the device for acquiring the multi-modal data of the brain. The device for acquiring the multi-modal data of the brain comprises light source probes, detection probes, a plurality of fixing devices and a head sleeve, wherein the fixing devices are installed on the head sleeve, the light source probes and the detection probes are connected to the fixing devices respectively, the light source probes and the detection probes are of the same structure, each light source probe and each detection probe respectively comprise a shell, an electroencephalogram electrode and an optical fiber bundle, the electroencephalogram electrodes are installed on the shells, the body of each optical fiber bundle is installed in the corresponding shell, and the two ends of each optical fiber bundle stretch out of the corresponding shell. The invention further provides the application of the probe for detecting the multi-modal data of the brain. By means of the application of the probes for detecting the multi-modal data of the brain, optimal brain data can be obtained through photoelectric synchronous detection. By the adoption of the arrangement mode, the number of channels for detecting multi-modal signals of the brain is increased to the maximum extent in the limited scalp space.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a brain multi-modal data acquisition device and application suitable for brain function cognition and brain-computer interface technology. Background technique [0002] Near-infrared spectroscopy (NIRS) and electroencephalography (EEG) are brain functional imaging techniques widely used in scientific research and clinical research. [0003] Near-infrared spectroscopy is a completely non-destructive in vivo optical detection technique. This technology utilizes the good penetrating ability of light in the near-infrared band in biological tissues, and reflects the various physiological parameters related to the optical characteristic parameters of the tissue through the light intensity or phase change of the emitted light after light is scattered and absorbed in the tissue. Variety. Biological tissue has the characteristics of low absorption and high scattering for near-...
