System Design of Transcranial Electromagnetic Stimulator Combined with tDCS and rTMS

Transcranial magnetic stimulation (TES) and transcranial magnetic stimulation (TMS) have been proved to be safe, effective and noninvasive means of functional regulation of the brain.which is widely used in the study of brain function and the rehabilitation therapy of nervous system diseases. There are many electrical stimulator and magnetic stimulation equipments in the market, but their functions are relatively simple. In order to meet the needs of electromagnetic combined therapy and medical experiments, this paper presents an electromagnetic stimulator that can achieve two functions: transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS). The stimulator can realize the key input and display of the stimulus parameters. The signal generator can output the direct current stimulation signal and the magnetic stimulation signal of the specific frequency. The stimulator can select the corresponding electrode and magnetic stimulation coil through socket, which can satisfy the basic electromagnetic stimulation needs. The design has a certain innovation and feasibility.
