A transcranial magnetic stimulation positioning method, system, device and medium based on electric field guidance

Abstract

This application discloses a method, system, device, and medium for transcranial magnetic stimulation (TMS) localization based on electric field guidance, belonging to the field of TMS technology. The method includes: acquiring an individual's local three-dimensional image block to be tested; obtaining an individual predicted local tissue segmentation block based on a segmentation model and the individual's local three-dimensional image block; acquiring the primary electric field distribution of the coil; obtaining a predicted local electric field block based on a local electric field estimation model, the individual predicted local tissue segmentation block, and the primary electric field distribution; constructing a candidate coil pose set based on the scalp projection position of the target point; calculating the average electric field intensity of each candidate coil pose in the gray matter region near the target point based on the predicted local electric field block; determining the candidate coil pose with the largest average electric field intensity as the optimal coil pose; and performing coil localization based on the optimal coil pose. This application can quickly and accurately achieve TMS coil pose localization, improving interpretability.
