Intraoperative motor area function localization system based on cortex electroencephalogram mu rhythm wavelet analysis

Abstract

The invention discloses an intraoperative motor area function localization system based on cortex electroencephalogram mu rhythm wavelet analysis, which collects cortex electroencephalogram signals by embedding an electrode array. The cortex electroencephalogram signals are treated by an amplification filter and output into a signal processing module through an analog to digital (A / D) converter. An electroencephalogram signal pretreatment unit of the signal processing module can previously treat and filter data collected by all electrodes through resolving and reconfiguration algorithm of the wavelet analysis. A mu rhythm feature extraction unit and a pattern classification unit perform feature extraction and classification based on mu rhythm feature extraction and classification algorithm to recognize special properties of all electrodes to finally process and output motor area localization images. The localization system can accurately and quickly detect motor area electroencephalogram signals and output brain motor area function localization images without wound. Through specificity analysis on brain motor area cortex electroencephalogram signals, clinical application of function localization in brain cortex motor area operation of human neurosurgery is achieved.

Description

technical field [0001] The invention relates to the field of medical electronic equipment, in particular to an intraoperative motor zone function positioning system based on cortical EEG mu rhythm wavelet analysis. Background technique [0002] Lesions in functional areas of the brain mainly refer to tumors, vascular malformations, and epileptic foci located in the motor, sensory, and language areas. The incidence of the large-scale investigation report organized by the World Health Organization in my country is only 8‰ of epilepsy. There are more than 10 million epilepsy patients in my country, of which drug-refractory epilepsy accounts for about 30% of epilepsy patients. At present, 3 million intractable epilepsy patients in my country need surgical treatment, which does not include low-grade glue located in functional areas. Tumors, metastases, primary benign tumors, cavernous hemangiomas, and arteriovenous malformations. Lesions in functional areas of the brain not only s...
