3D scanning transcranial magnetic stimulation system and transcranial magnetic stimulation method

Abstract

The invention discloses a 3D scanning transcranial magnetic stimulation system and a transcranial magnetic stimulation method. The system comprises: a 3D scanning modeling system. The 3D scanning modeling system uses a 3D scanner to scan a head image of a tester and establish a head mold image in real time; 2, a matching positioning system, wherein the matching positioning system matches the headmold image established by the 3D scanning modeling system with meninges to precisely locate stimulation points; 3, a t system, wherein that test system manipulate a robot to perform transcranial magnetic stimulation according to a positioning stimulation point; 4, a fNIRS signal acquisition system, wherein that fNIRS signal acquisition system is use for acquiring near-infrared signal of a tester'sbrain region, comparing changes of near-infrared signal in real time, accurately finding out insufficient stimulation or excessive stimulation, and feeding back the result to the test system. In order to accurately perform transcranial magnetic stimulation (TMS), 3D head-mold images are matched with meninges and a real-time fNIRS signal acquisition system is used to establish a simulation experiment.

Description

technical field [0001] The invention belongs to the technical field of neurological disease treatment and brain function research, and in particular relates to a 3D scanning transcranial magnetic stimulation system and a transcranial magnetic stimulation method. Background technique [0002] Transcranial magnetic stimulation (TMS) is a new technology of non-invasive cerebral cortex stimulation and modulation that appeared after 1985, and has been widely used in brain science research, clinical diagnosis and treatment. TMS uses a pulsed magnetic field to act on the central nervous system, changing the membrane potential of cortical nerve cells, causing them to generate induced currents, affecting the metabolism and neuroelectric activity in the brain, thereby causing a series of magnetic stimulation technology of physiological and biochemical reactions. Transcranial magnetic stimulation technology has been widely used in neurological disease treatment and brain function resea...

AI Technical Summary

Problems solved by technology

[0008] Most of the existing stimulation systems select relevant stimulation parameters based on the experience of professionals, such as stimulation intensity, stimulation frequency, and stimulation time, and cannot quantify the stimulation effect, and dynamically adjust according to the quantitative results

Empirical parameter settings and traditional stimulation modes are difficult to meet individualized treatment needs, which can easily lead to over-stimulation or under-stimulation, and cannot achieve effective or optimal stimulation effects

[0009] At present, the method of regulating TMS with electroencephalogram (EEG) is also proposed, but there are technical problems in the monitoring of the patient's EEG during the TMS pulse process, because the high-energy dynamic magnetic field generated by the TMS device will induce in the EEG lead. Unexpected voltage, so the EEG signal is generally detected when no TMS pulse stimulation is generated, and there are limitations in use
