Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention is further described in detail.

[0028] The fusion brain network construction method based on structural connection and functional connection provided by the present invention is a brand new brain network construction method. From the perspective of multimodal fusion, this method fuses the structural brain network and the resting-state functional brain network; the specific implementation steps are as follows:

[0029] Step S1: preprocessing the diffusion tensor imaging, and then performing region segmentation on the preprocessed diffusion tensor imaging according to the selected standardized brain atlas;

[0030] In the step S1, the preprocessing is carried out using brain functional magnetic resonance imaging software (FMRIB Software Library, FSL), and the preprocessing steps specifically include: magnetic susceptibility correction, eddy current dist...

Abstract

The present invention relates to the fields of brain function imaging and the construction of a brain network and specifically relates to a fusion brain network construction method based on structuralconnection and functional connection. The purpose of the present invention is to provide a brain network construction method with the fusion of two types of connections with the combination of the advantages of existing structural brain network and resting state function brain network in disease research, and the method is the fusion brain network construction method based on the structural connection and the functional connection. According to the method, a structural connection matrix and a resting state functional connection matrix are fused. According to the fusion brain network construction method, the difference of network attribute indexes of a brain network of a patient with brain diseases and a brain of normal people can be more effectively found, and the research of various brain diseases is helped.

Description

technical field [0001] The invention relates to the field of brain functional imaging and the field of brain network construction, specifically a method for constructing a fusion brain network based on structural connection and functional connection, which uses a fusion brain network based on two modes of structure and function to reconstruct the human body The brain network provides a certain basis for the understanding of the internal working mechanism of the brain, the study of the rules of neural activity in the brain, and the study of brain diseases. Background technique [0002] The human brain can be regarded as a highly complex network composed of multiple neurons, neuron clusters or multiple brain regions connected to each other. This large and complex network is the physiological basis for information processing and cognitive expression in the brain. After fully realizing the importance of building a human brain network, some neuroscientists proposed the concept of...
