Apparatus and method for closed loop tfus stimulation

Abstract

A transcranial Focused Ultrasound (tFUS) system uses a neural network to correct skull aberrations and maximizes the transmission of ultrasound waves through the skull. A method using supervised learning generates aberration correction parameters to be used by the receiver and transmitter of the tFUS system. A method utilizing these aberration correction parameters operating on the tFUS system maximizes the coherence of ultrasound waves passing through the skull. The method maximizes the amount of power transmitted through the skull, given a fixed maximum pressure (for example, determined by regulatory requirements).
