A Low Intensity Ultrasound Neural Modulation System for Brain Stimulation

JIAXING YANG, HONG ZHANG

Abstract


Non-pharmacological and non-surgical transcranial stimulation of the nerve function may become a new and very effective treatment of cranial nerve diseases. In this paper, a low-intensity portable ultrasound system was designed, which includes the arc-phased array and the ultrasonic electronic system. The arc phased array is composed of 203 single transducers. The electronic system includes ultrasonic signal generator, amplifier and delay unit. The system can independently modulate the frequency of 203 output signals and its frequency resolution is less than 1Hz, the phase difference is adjustable and less than 0.1degrees. It can focus on different parts of the brain by controlling the delay parameters.
