Design of driving circuit for ultrasonic brain stimulation based on FPGA

Ultrasound brain stimulation technology is a new method of brain stimulation which developed in recent years, with no damage, high spatial resolution, penetrating and so on, however, it is possible to lack of stimulate strength and not achieve the purpose of stimulation. For this, we design the driving circuit for ultrasonic brain stimulation based on FPGA in this paper, the system can drive multi-center frequency ultrasonic transducer, customize to adjust the excitation pulse waveform, control the gain of the amplifier, and collect the data of multi-sampling clock frequency. Many nerve diseases that difficult to be cured in the medical field will usher in new breakthroughs in the treatment by using ultrasound to stimulate. Finally, the driving circuit for ultrasonic brain stimulation based on FPGA developed in this paper which can obtain the ultrasound waveform with different sampling frequency and lay the foundation for brain stimulation experiments for the next step.
