Navigation transcranial magnetic stimulation treatment system

Abstract

The invention relates to a navigation transcranial magnetic stimulation treatment system, which mainly comprises a small size nuclear magnetic resonance imaging system, an optical positioning navigation system and a transcranial magnetic stimulation machine, wherein the small size nuclear magnetic resonance imaging system is connected with a microcomputer of the transcranial magnetic stimulation treatment system, the scanned imaging data obtained by the scanning of the small size nuclear magnetic resonance imaging system is transmitted into a microcomputer data base; the optical positioning navigation system arranged in the navigation transcranial magnetic stimulation treatment system calls the imaging date for 3D model reconstruction, registers and stimulates a coil after the reconstruction, and guides the fixing position of the coil to ensure that the stimulated focus of the coil is coincident with an appointed stimulation point; a high-voltage pulse generator of the transcranial magnetic stimulation machine acts on the coil; and the transcranial magnetic stimulation machine and the optical positioning navigation system are both connected to the microcomputer of the transcranialmagnetic stimulation machine, and displayed independently by screens when in working. The invention has the advantages of convenient operation, accurate positioning, stimulation pertinence and strongfunction, and can be widely applied to the departments of psychiatry, neurology and rehabilitation.

Description

technical field [0001] The invention relates to a navigation transcranial magnetic stimulation treatment system, specifically, it includes a navigation transcranial magnetic stimulation special small magnetic resonance system, an optical positioning navigation system and a transcranial magnetic stimulation instrument based on a labview development platform. treatment system. [0002] The present invention also relates to a positioning method of the optical positioning and navigation system in the above-mentioned navigation transcranial magnetic stimulation treatment system. Background technique [0003] Transcranial Magnetic Stimulation (TMS) is a cortical stimulation method first created by Barker et al. in 1985. It has the advantages of painless, non-invasive, easy to operate, safe and reliable, and has been clinically applied soon. The so-called "transcranial" means that the magnetic signal can pass through the skull without attenuation to stimulate the cerebral cortex. ...

Problems solved by technology

[0005] Most of the currently known transcranial magnetic stimulators do not have a supporting navigation and positioning system to guide their precise stimulation. When using it, they often rely on the doctor's experience to stimulate at "probable" parts. The stimulation is not accurate, and the therapeutic effect is greatly reduced. At the same time, it will mislead the doctor's judgment and deny that it may be the correct treatment plan

A small number of instruments are equipped with navigation and positioning systems. At present, there are two main situations. One is mechanical positioning. The coil is positioned by triggering the patient's motion-evoked potential and the mechanical positioning tool. The disadvantage is that the mechanical positioning tool is complicated and the operation steps are cumbersome. General operators do not know how to use it or use it poorly; the other is optical navigation and positioning. The operation is mainly concentrated on the navigation and positioning software, but in order to reconstruct the 3D model of the patient's head, it often requires cross-departmental cooperation, and the patient travels between departments. , in order to obtain the head scan picture of the patient's nuclear magnetic resonance (MRI), the operability is poor

The current large-scale MRI system in the hospital can image multiple parts of the whole body, and requires high field strength and uniform area indicators, so the magnets are relatively large. For example, the conventional permanent magnet 0.35T MRI system has a magnet weight of about 16 tons and a magnet size 1.3*3*2m, the superconducting body is larger and can only be placed at the bottom of the hospital, and in order to shield the interference signals from the outside world to the human body and the coil, it is necessary to build a shielding room, which cannot flexibly cooperate with the transcranial navigation Magnetic stimulator use
