Transcranial magnetic stimulation coil position and posture positioning device, method and equipment for brain map navigation

Abstract

The invention belongs to the technical field of cognitive neuroscience, and specifically relates to a transcranial magnetic stimulation coil position and posture positioning device, method, and equipment for brain atlas navigation, aiming to solve the problem that the prior art cannot realize quantitative and accurate scalp maps based on brain atlases Problems describing the position and orientation of the stimulation coil. The method includes obtaining the location and direction of the stimulating coil array in the individual brain space; registering the structural magnetic resonance image with the brain network group atlas, and mapping with the stimulating coil array in the individual brain space after registration to obtain the scalp atlas map ; Calculate the conversion relationship between the visual sensor and the stimulating coil array in the individual brain space; obtain the real-time pose of the stimulating coil in the stimulating coil array in the individual brain space, if it is consistent with the position and direction of the stimulating coil array in the individual brain space If the difference is greater than the set difference threshold, the pose of the stimulation coil is adjusted. The invention realizes the quantification and accurate description of the position and direction of the stimulation coil based on the scalp map based on the brain atlas.

Description

technical field [0001] The invention belongs to the technical field of cognitive neuroscience, and in particular relates to a transcranial magnetic stimulation coil pose positioning device, method and equipment for brain atlas navigation. Background technique [0002] Currently, an important challenge facing researchers in the field of neuroscience is to precisely locate non-invasive neuromodulation devices. With non-invasive neuromodulation technologies represented by Transcranial Magnetic Stimulation (TMS) and Transcranial Electrical Stimulation (TES), precise neuromodulation device positioning can achieve the best regulation effect. [0003] The efficacy of non-invasive neuromodulation techniques is widely recognized in the clinical practice of psychiatric disorders. The clinical application of the existing transcranial magnetic stimulation technology can only determine the scalp positioning of the stimulation coil according to the operator's experience, such as the posi...
