Ultrasound transducer and amplifier design in transcranial ultrasound stimulation system

Non-pharmacological and non-surgical transcranial stimulation of the nerve function may provide new opportunities in evaluation and treatment of cranial nerve diseases. Stimulation can additionally help to uncover the mechanism of various brain processes by temporarily altering the normal function of healthy brains. Transcranial ultrasound stimulation(TUS) is in the early stages of human applications, theoretically it could offer enhanced spatial resolution and targeting relative to other noninvasive techniques, given the highly focused energy source that is delivered. Ultrasound transducer and amplifier are the essential devices to complete the TUS experiment, the devices designed by ourselves has the advantages of high flexibility and easy adjustment of the acoustic field parameters.
