Problems solved by technology

[0004] However, due to the immature development of the current near-infrared brain imaging technology, there are still the following problems: the waveform of the near-infrared light emitted by the light source in the existing near-infrared brain imaging system is relatively simple, and the output waveform of the light source cannot be dynamically adjusted to adapt to different conditions. Different test items and different testees lead to poor adaptability of the product

Abstract

The invention discloses a method and device for measuring oxygen-containing hemoglobin and deoxygenated hemoglobin and equipment. The device comprises a near-infrared emission module, a near-infraredreceiving module and a controller, wherein the near-infrared emission module is used for emitting near-infrared light of target compound waveforms to the tested cerebral cortex, the near-infrared receiving module is used for receiving a luminous intensity signal, reflected by the tested cerebral cortex, of the near-infrared light, and the controller is used for receiving target measuring requirement parameters, adjusting the near-infrared light waveforms emitted by the near-infrared emission module according to the target measuring requirement parameters to obtain the target compound waveforms, controlling the near-infrared emission module to emit the near-infrared light according to the target compound waveforms, receiving luminous intensity information output by the near-infrared receiving module, and measuring oxygen-containing hemoglobin parameters and deoxygenated hemoglobin parameters of the tested cerebral cortex according to the luminous intensity information. In this way, thefunction of dynamically adjusting output waveforms to adapt to different testing items and different testees is achieved, and the using adaptability of products is improved.

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, a method 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-inv...
