Near-infrared brain function imager 3D analysis system based on HCT

Abstract

The invention relates to a brain function detection system, and particularly relates to a near-infrared brain function imager 3D analysis system based on HCT. The system comprises a near-infrared brain imaging device, an HCT cognitive task module, a storage module and a map analysis module, wherein the near-infrared brain imaging device is used for collecting infrared waveform signals of a subject and generating an infrared brain imaging spectrum; the HCT cognitive task module is used for providing high-level cognitive tasks for the subject; the storage module is used for storing the infrared brain imaging spectrum generated by the near-infrared brain imaging device; the map analysis module is used for analyzing and calculating the infrared brain imaging spectrum collected by the near-infrared brain imaging device and is normal; and the high-level cognitive tasks include memory training, operation training, logical thinking training, abstract thinking training and reverse thinking training and are used for comprehensively evaluating the judgment ability, language ability, attention, thinking ability, combination ability and imagination ability of the subject. The infrared brain imaging device based on HCT collects maps based on the HCT cognitive task module, and more remarkable brain imaging map collection can be achieved.

Description

technical field [0001] The invention relates to a brain function detection system, in particular to a 3D analysis system for a near-infrared brain function imager based on HCT. Background technique [0002] Since the 1970s, near-infrared spectroscopy (NIRS) has become a non-invasive technology for measuring blood oxygen levels in vivo. This technology uses changes in light intensity caused by hemoglobin to measure blood oxygen levels in local tissues. Frans Jöbsis is the creator of In Vivo NIRS. In 1977 he published the real-time non-invasive detection of oxyhemoglobin by transmission spectroscopy. After the discovery in 1992 that near-infrared spectroscopy (NIRS) could detect functional activity in the human cerebral cortex (changes in blood oxygen levels), the technology has rapidly developed in brain function research and clinical applications. It utilizes the good penetration effect of near-infrared light on organisms, emits near-infrared light through the optical fibe...

Problems solved by technology

[0004] However, when the existing near-infrared brain imager collects the spectrum, the resulting spectrum is generally difficult to identify, and the identification and understanding of the spectrum are cumbersome, which cannot play a greater role in clinical practice. Moreover, NIRS data can only be used in two The display in the form of a dimensional curve cannot provide a more vivid and intuitive map result display for the diagnostician
