Intracranial treatment envelope mapping of transcranial focused ultrasound

Abstract

Presented here are the results of a volumetric, thermal treatment envelope map for transcranial focused ultrasound. The aim was to determine the treatable volume of the intracranial cavity in order to identify potential clinical applications and direct future research efforts. It was determined that thalamic targets are optimal for both transcranical MRg-FUS systems used in this work, which operate at 220 kHz and 650 kHz, respectively. It is hoped that future research efforts will focus on expanding these treatment envelopes in order to expand the possible neurosurgical applications for this technology. © 2012 American Institute of Physics.
