MR-guided High Intensity Focus Ultrasound is an appealing technology in neurosurgery. For such application, accurate targeting and monitoring are crucial. A recent sequence allowing simultaneous measurements of temperature and displacement measurements is used to identify in real-time both the focal point by Acoustic Radiation Force Intensity (ARFI) and verify the absence of heating during ARFI sonication. The method has been evaluated in vivo in a non-human primate under anesthesia with a single-element transducer. A comparison with in-silico focused ultrasound simulation is also provided.
