Abstract

A transcranial magnetic stimulation (TMS) coil positioning device includes a stimulation coil (1), a coil position tracking module (2), a head fixing frame (3), a head position tracking module (4), athree-dimensional mobile seat (5), a camera (6), a coil rotating device (7), a control system (8), an image processing module (9), an electromagnetic field calculation module (10), and a display (11).The image processing module (9) reconstructs the three-dimensional head model of a patient in an image space. The electromagnetic field calculation module (10) obtains the optimal coil position and angle by inversion according to the position of a nerve fiber to be activated in a target treatment target area. The control system (8), by means of the camera (6), the coil position tracking module (2), the coil rotating device (7), the head position tracking module (4), the head fixing frame (3) and the three-dimensional mobile seat (5), adjusts the relative position and angle of the stimulationcoil (1) and a patient head (12) to a target position and a target angle.

Description

technical field [0001] The invention relates to a medical device, in particular to a transcranial magnetic stimulation coil positioning device. Background technique [0002] In the early 1980s, British scientists Baker and others began to study the use of magnetic stimulation to intervene in brain neural activity, and successfully stimulated the motor center of the human brain for the first time in 1985, and measured the motor cortical evoked potential (Motor- evoked potentials, MEPs). This also marks the entry of Transcranial Magnetic Stimulation (TMS) into the stage of history. With the development of high-power devices and the improvement of circuits, repetitive Transcranial Magnetic Stimulation (rTMS) appeared in the late 1980s, which can generate 1–100 pulses per second. According to the principle of electromagnetic induction, the magnetic stimulator releases the energy stored in the capacitor into the stimulating coil in a short time to form a pulse current, and then...
