Device for measuring oxygenated hemoglobin and deoxygenated hemoglobin and brain imaging device

Abstract

The invention discloses a device for measuring oxygenated hemoglobin and deoxygenated hemoglobin and a near infrared brain imaging device. The device comprises an interface module, a near infrared receiving and transmitting module and a controller, wherein the near infrared transceiving module is provided with a plug-and-play interface and plugged in the interface module through the plug-and-playinterface, the near infrared receiving and transmitting module is driven by the controller to transmit preset-wavelength near infrared rays to measured cerebral cortex and receive light intensity signals generated when the near infrared rays are reflected by the measured cerebral cortex. The controller is connected with the interface module and used for receiving the light intensity signals outputby the near infrared receiving and transmitting module and measuring parameters of oxygenated hemoglobin and deoxygenated hemoglobin of the measured cerebral cortex according to the light intensity signals. Thus, according to the characteristic that hot plug is supported by the near infrared receiving and transmitting module, the aims of increasing and decreasing functions and channel number canbe realized, and the reusability of the device and the usage rate of parts can be increased.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to a device for measuring cerebral cortex oxygenated hemoglobin and deoxygenated hemoglobin and a near-infrared brain imaging device. Background technique [0002] The development of optical imaging technology provides new and important research means for the study of brain mechanism of cognitive activities. Optical imaging can reveal the structural and functional information of the nervous system at different levels, and provide an important experimental basis for explaining cognitive activities from a new perspective. Near Infrared Spectroscopy (NIRS for short) is developing rapidly in optical imaging, which can provide high-resolution images for observing the functional columns of the cerebral cortex. Near-infrared spectroscopy, which penetrates the skull, has been used for non-invasive studies of brain function in animals and children. [0003] In related technologies,...
