Abstract

The invention discloses a preoperative brain functional network positioning method based on resting-state functional magnetic resonance. The method comprises the steps of constructing a dissection template by task-state functional magnetic resonance according to a position of a nidus brain zone, performing resting-state functional magnetic resonance scanning, performing resting-state functional magnetic resonance data resolution by an independent component analysis method to extract brain functional networks, performing similarity matching on the brain functional networks by a template matching method to find out the most similar brain functional network and the second similar brain functional network, and performing analysis processing to obtain the optimum brain functional network for preoperative functional positioning. The method solves the three classic problems that the traditional preoperative positioning seed point is difficult to determine, the order number of an independent component analysis model is difficult to determine, and component recognition is great in subjectivity and fallible; and the method allows the preoperative positioning to be objective, accurate, automatic, simple and convenient.

Description

technical field

[0001] The invention relates to medical image processing auxiliary technology, which is an automatic functional network screening method based on independent component analysis results of resting brain functional imaging, and is used for automatic identification of brain functional networks for neurosurgery preoperative positioning. Background technique

[0002] Intracranial tumors include primary brain tumors and metastatic tumors, accounting for about 5% of systemic tumors and 70% of childhood tumors. Because of its expansive and infiltrating growth, when it occupies a certain space in the brain, no matter whether its nature is benign or malignant, it will inevitably increase intracranial pressure, compress brain tissue, cause central nervous system damage, and endanger the patient's life. The primary treatment for intracranial tumors is brain surgery. The principle is to remove as much of the tumor as possible while preserving neurological function to the ...
