Scalp electroencephalogram electrode rapid positioning method and positioning model

Abstract

The invention discloses a scalp electroencephalogram electrode rapid positioning method and a positioning model. The scalp electroencephalogram electrode rapid positioning method is characterized by comprising the following steps: acquiring craniofacial model parameters of a patient through skull CT or magnetic resonance MRI thin-layer scanning; preparing a craniofacial model by adopting 3D printing according to the craniofacial model parameters, and determining the positions of electrodes in the craniofacial model to form a craniofacial positioning model; and fitting the craniofacial positioning model to the scalp surface of the patient, and enabling the positions of the electrodes determined in the craniofacial positioning model to be in one-to-one correspondence to the mounting positions of the electrodes, thus completing the rapid positioning of scalp electroencephalogram electrodes. With the adoption of the scalp electroencephalogram electrode rapid positioning method and the positioning model, the rapid and accurate positioning is realized, meanwhile, the same positioning is repeated during the secondary review, and thus the comparison effect is greatly improved.

Description

technical field [0001] The invention relates to a positioning method and a positioning model applied to scalp electroencephalogram electrodes. Background technique [0002] EEG is an important basis for the diagnosis of epilepsy and other diseases in neurology. The EEG signals are collected through the EEG electrodes placed on the scalp. The accuracy, speed, and tight coupling of the electrode installation directly affect the clarity of the results. and reliability. [0003] In the past, the EEG scalp electrodes were installed using the internationally accepted 10 / 20 / system method. It was necessary to manually measure and draw lines on the scalp with a tape measure. This manual method has deviations in determining the position of the electrodes and is less accurate. Poor, it takes a long time, and it cannot be tolerated by children and other patients who cannot cooperate; at the same time, it needs to be repositioned during the second reexamination, which cannot guarantee r...
