Abstract

The invention discloses an automatic detection method for epilepsy electroencephalography (EEG) / magnetoencephalography (MEG) abnormal waves and a positioning system The method comprises the followingsteps: 1) segmenting EEG / MEG data of each sample to obtain a plurality of EEG / MEG data segments, wherein each EEG / MEG data segment is a data set in a two-dimensional matrix form; 2) training an EEG / MEG multi-view abnormal wave detection model by utilizing the EEG / MEG data fragments; 3) performing artifact removal operation on an EEG / MEG signal to be processed, and then segmenting the EEG / MEG datato obtain a plurality of EEG / MEG data segments; 4) respectively inputting the obtained EEG / MEG data fragments into the trained EEG / MEG multi-view abnormal wave detection model to obtain abnormal waveclassification results corresponding to the EEG / MEG data fragments; and 5) determining whether the EEG / MEG signal to be processed has abnormal waves or not according to the obtained abnormal wave classification result.

Description

technical field [0001] The invention belongs to the field of signal recognition in the field of biometric feature recognition, and specifically relates to a method for detecting abnormal waves of EEG / MEG in epilepsy and a traceability positioning system based on deep learning. Background technique [0002] As one of the most common neurological brain diseases, epilepsy caused by recurrent seizures affects about 1% of the population worldwide, and almost 30% to 40% of patients do not respond to drugs, which has a significant impact on their physical, mental and social health. negative impact. Surgery is an effective treatment for patients with drug-resistant epilepsy, and the key lies in identifying the brain region (seizure-induced zone) that produces the seizure. Epilepsy spikes are a widely accepted canonical biomarker as one of the abnormal EEG / MEG waves in epilepsy to identify epilepsy-occurring regions. Therefore, abnormal wave analysis can be used in the preoperative...
