Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

A comparative evaluation of three hydrophones and a numerical model in high intensity focused ultrasound fields

, 2011
The pressure fields of two different high intensity focused ultrasound (HIFU) transducers operated in burst mode were measured at acoustical power levels of 25 and 50 W (continuous wave equiva- lent) with three different hydrophones: A fiber-optic ...

HIFU Beam Imaging Based on Scattering Signals from Focal Area [PDF]

, 2013
High-Intensity Focused Ultrasound (HIFU) is one of minimally invasive surgical procedures. However there are refractions and reflections which cause the actual focal point deviates from the geometrical focal point of transducer.

The use of histotripsy as intratumoral immunotherapy beyond tissue ablation—the rationale for exploring the immune effects of histotripsy

International Journal of Hyperthermia, 2023
Mechanical high-intensity focused ultrasound (M-HIFU), which includes histotripsy, is a non-ionizing, non-thermal ablation technology that can be delivered by noninvasive methods. Because acoustic cavitation is the primary mechanism of tissue disruption,

Staged Bilateral Magnetic Resonance‐Guided Focused Ultrasound for Treating Essential Tremor: Systematic Review and Meta‐Analysis

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Unilateral magnetic resonance guided focused ultrasound (MRgFUS) thalamotomy reduces tremor in essential tremor, yet disability often persists on the untreated side. The added benefit and safety of a staged contralateral lesion remain uncertain.
