BRAIN STIMULATION DEVICE USING ULTRASONIC WAVES AND METHOD USING SAME

摘要

Disclosed are a brain stimulation device and method using ultrasonic waves. The brain stimulation device using ultrasonic waves comprises: a target position calculation unit for calculating, on the basis of an image of the skull of a user which has been obtained in advance and an image of the skull of the user which has been photographed through at least one marker, an ultrasonic wave target position to be irradiated by ultrasonic waves; a phase adjustment unit for adjusting the phase of each of a plurality of piezoelectric elements so that a multi-focus is formed at the ultrasonic wave target position; and an ultrasonic wave conversion unit for converting an electric signal into an ultrasonic wave signal by applying the electric signal to the plurality of piezoelectric elements which have been phase-adjusted so that ultrasonic waves are irradiated on the ultrasonic wave target position. Accordingly, it is possible for ultrasonic waves to irradiate the exact position of the brain which needs to be stimulated and it is possible to prevent permanent damage to the brain by shortening the ultrasonic wave stimulation time.
