Abstract

The invention discloses a near-infrared cerebral oxygen detection system and method. The near-infrared cerebral oxygen detection system is provided with multiple detection units, thereby being conductive to improving the detection resolution ratio; in addition, near-infrared light sources and photoelectric sensors are staggeredly arranged, thereby reducing the reception of interference signals toreduce the noise of the interference signals, effectively improving the accuracy and precision of cerebral blood oxygen data, and solving the technical problem of low data precision of a near-infraredspectrum cerebral oxygen detection system in the prior art. In addition, the near-infrared cerebral oxygen detection system adopts a producer / customer mode in data reading and processing links, thereby effectively improving the running efficiency of a program, increasing the acquisition speed of the cerebral blood oxygen data, and improving the real-time property of data acquisition.

Description

technical field [0001] The invention relates to the field of brain information collection, in particular to a near-infrared brain oxygen detection system and method. Background technique [0002] In recent years, near-infrared spectroscopy (Near-infrared Spectroscopy, NIRS), which is an emerging force in medical image technology, is gradually being applied in the field of biomedicine, and has become a research hotspot. The principle of NIRS imaging is the interaction between light and brain tissue. NIRS is based on the absorption spectrum of the main chromophores in living tissue, combined with the law of light propagation in tissue, and using the characteristics of good penetration ability of near-infrared light. Study the information it carries when it passes through a series of absorption and scattering in the tissue and then exits. [0003] In addition, near-infrared spectroscopy has been widely used as a brain oxygen monitoring technology. This technology uses the rela...
