MR-Guided Transcranial Focused Ultrasound
2016Previous chapters introduced the ability of using focused ultrasound to ablate tissues. It has led to various clinical applications in the treatment of uterine fibroid, prostate or liver cancers. Nevertheless, treating the brain non-invasively with focused ultrasound has been considered beyond reach for almost a century: The skull bone protects the ...

Transcranial Focused Ultrasound Surgery
Topics in Magnetic Resonance Imaging, 2006The development of high-intensity ultrasound technology into a system for performing image-guided noninvasive ultrasound neurosurgery has developed at a relatively rapid pace in the past few years. Magnetic resonance imaging has contributed significantly to this development by providing a modality by which percutaneous ultrasound treatments can be ...

Binary acoustic metasurfaces for transcranial focused ultrasound
The Journal of the Acoustical Society of America, 2023Transcranial focused ultrasound is a promising technique for noninvasive and spatially targeted diagnosis and treatment of brain diseases. Acoustic lenses were designed to correct the skull-induced beam aberration, but these designs could only generate static focused ultrasound beams inside the brain.

Current and future uses of transcranial focused ultrasound in neurosurgery
Journal of Neurosurgical Sciences, 2018Focused ultrasound (FUS) produces a region of high intensity at the focal zone of the beam but with minimal effects at adjacent areas, allowing the sonication of deep targets throughout the body. Despite early obstacles to transmitting ultrasound energy through the skull, recent advances in ultrasound technology, software, and real-time monitoring have

Effects of parameter errors in the simulation of transcranial focused ultrasound
Physics in Medicine and Biology, 2001Previous numerical simulation work has supported experiments showing that a sharply focused transcranial ultrasound field can be generated for noninvasive therapy and surgery in the brain. The predicted pressure gain and optimal sonicating frequency could be affected by uncertainty in the simulation parameters. We estimate the effects of uncertainty in

The use of transcranial focused ultrasound in CNS diseases
Voprosy neirokhirurgii imeni N.N. Burdenko, 2016Transcranial focused ultrasound is a modern medical technique, which provides non-invasive impact on the brain. Current development stage of this technique is no longer than 20 years and many possible applications of this technique are still at pre-clinical stage. The greatest progress has been made in the field of functional neurosurgery.

Skull Impact on the Ultrasound Beam Profile of Transcranial Focused Ultrasound Stimulation
2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019Transcranial focused ultrasound stimulation (tFUS) is a promising noninvasive neuromodulation tool for targeting brain regions with millimeter-scale spatial resolutions. In conventional tFUS studies, a focused ultrasound beam generated by an external ultrasound transducer is delivered to the neural target.
