Problems solved by technology

[0009] To sum up, increasing the depth of magnetic field pulse stimulation in the existing deep TMS transcranial magnetic stimulator will inevitably lead to an increase in the intensity of magnetic field pulse stimulation to the cortex, resulting in an increase in the probability of side effects under the condition of pulse stimulation intensity. Weak magnetic field pulse stimulation intensity, increasing the range of magnetic field pulse stimulation by means of repetitive scanning and rotating scanning of the target area by the robotic arm, which is costly and cumbersome to operate

Abstract

The embodiment of the invention discloses a control method of a transcranial magnetic stimulator, and the method comprises the steps: configuring a discharge peak current in a coil according to pre-calculated data, generating a dynamic sweeping transient magnetic field in a target region according to a time sequence, and further generating a dynamic sweeping induced electric field. Repeated sweeping and rotary sweeping of an intracranial target region are achieved by controlling the transient magnetic field, the transient magnetic field pulse regulation and control stimulation range can be increased, meanwhile, the stimulation intensity of the cerebral cortex magnetic field pulse is prevented from being increased, and the possibility of side effects under the condition that the stimulation intensity of the pulse is increased is reduced. According to the control method, a coil does not need to be moved, and the target region can be regulated, stimulated and swept in a low-cost and convenient-to-operate manner; and the control method does not need precise mechanical control operation.
