TRANSCRANIAL ULTRASOUND FOCUSING
Dossier Overview
Inventor
Oron ZACHAR
IPC Classification
CPC Classification
Embodiments of the invention introduces a method and system for focusing ultrasonic energy through intervening skull tissue into a target site within a target brain tissue region under the skull, includes a transducer emitter array, a transducer receiver array, a processor receiving echo signals from the receiver to determine correction factors for the transducer elements to compensate for refraction occurring due to intervening tissue. The correction factors may include phase correction factors, and the phases of excitation signals provided to the transducer elements may be calibrated focusing based upon the phase correction factors to focus the ultrasonic energy to the tissue at the target site.
