Transcranial magnetic stimulator master control system based on NI card

Abstract

The invention discloses a transcranial magnetic stimulator main control system based on an NI card. The syste, comprises an upper computer and a system state detection module connected with the uppercomputer, wherein a NI card is arranged in the upper computer, the other end of the system state detection module is respectively connected with a plurality of charging signal conditioning modules anda plurality of discharging signal adjusting modules; high-precision time synchronization work between two paths of stimulation can be realized, in the two paths of discharging stimulation signal conditioning and driving modules, conditioning and reconstruction are carried out on signals from a hardware level, and the precision is high; the type of a configured coil can be accurately identified soas to enter different stimulation modes; the operation accuracy is improved, and misoperation is avoided; and a capacitor, an IGBT and a multi-stage high-power resistor form a communication loop to discharge the residual voltage of the capacitor, so that the equipment is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of transcranial magnetic stimulation, in particular to a main control system of a transcranial magnetic stimulation apparatus based on an NI card. Background technique [0002] The principle of the transcranial magnetic stimulator is to charge the capacitor with a specific value, and then discharge the stimulating coil instantaneously, thereby generating a transient magnetic field, using this magnetic field to deeply stimulate different parts of the human brain, so as to regulate brain function diseases the goal of. [0003] Most of the transcranial magnetic stimulation instruments on the market can only perform single-point therapy and it is inconvenient to adjust the stimulation point; the patient needs to lie flat when using it. Place it on the corresponding position of the head to start the treatment. If the patient changes position slightly, or if the body moves slightly away from the magnetic field s...

AI Technical Summary

Problems solved by technology

Every time you change the treatment point, you need to re-measure the threshold and re-fix the stimulation coil, which is cumbersome to operate

[0004] In the current similar products, it is impossible to adjust the multi-channel charge and discharge stimulation signals, which cannot meet the work needs. On the other hand, it cannot monitor the s...
