Design and Construction of a Microcontroller Based Transcranial Magnetic Stimulator

摘要

In this study, a microcontroller based repetitive transcranial magnetic stimulator (rTMS) was designed and tested at low voltage levels. Design parameters of the rTMS were determined and three PIC microcontrollers were employed for controlling these parameters in the system. The frequency of stimulation pulses can be set for a predetermined value via microcontroller on which one of the outputs is PWM. The other novelty of the designed system is the remote control of stimulation pulse, which uses an ASK modulation technique. A performance test of the system was performed and the stimulation pulse was analyzed. At the result, design parameters and measurement parameters were compared with each other.
