Method, system and equipment for detecting asymmetry of left and right hemispheres of brain as well as storage medium

Abstract

The invention discloses a method, system and equipment for detecting asymmetry of left and right hemispheres of a brain as well as a storage medium, and relates to the field of image processing. According to the method, magnetic resonance scanning data of the brain of each detected individual are acquired and processed to obtain quantitative nuclear magnetic resonance data of the brain of each detected individual, the average value of the quantitative nuclear magnetic resonance data in target brain area ranges of left and right hemispheres is extracted according to a mask matrix, a lateralization index is calculated by using the average value, and detection of the asymmetry of left and right hemispheres of the brain is conducted according to the lateralization index to obtain a detection result. Detection of the asymmetry of left and right hemispheres of the brain of each individual is conducted by the quantitative nuclear magnetic resonance method, the asymmetry of left and right hemispheres of the brains of different detected individuals is analyzed quantitatively from a microstructure perspective, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a detection method, system, device and storage medium for the asymmetry between the left and right hemispheres of the brain. Background technique [0002] The human brain has two hemispheres, left and right. The division of labor and cooperation between the left and right hemispheres provide important support for human daily life. However, the left and right hemispheres of the human brain are asymmetrical both in structure and function. This hemispheric lateralization phenomenon widely exists in different brain regions, revealing the specific manifestation of different cognitive functions in the human brain. Research on the asymmetry of the left and right hemispheres of the brain can be verified from both structural and functional aspects. In terms of function, for example, in related technologies, functional imaging technology is used to detect the functional asymmetry between t...

AI Technical Summary

Problems solved by technology

[0003]However, the method of measurement by autopsy is severely limited by participant origin, sample composition, sample size, sample number, and location of stained cells, and is limited in the measurement of left-right hemispheric asymmetry The link between sex and cognitive function is often unknown

The functional imaging technology of the asymmetry of the left and right hemispheres of the brain taken from a living body is a qualitative analysis method, which cannot well reflect the results of the asymmetry of the left and right hemispheres based on individual differences.
