Real-time beam visualization and therapy planning for focused ultrasound therapies using a diagnostic imaging array
… a tissue-mimicking phantom and in vivo. Passive cavitation detection (PCD) measurements found that an imaging array can induce stable cavitation in microbubbles and could therefore be used to administer some low intensity FUS treatments.

The Physical Mechanism of Blood-Brain Barrier Opening Using Focused Ultrasound and Microbubbles
… To accomplish this goal, an in vivo transcranial cavitation detection system was developed and tested, built in phantoms and in vivo, to monitor the behavior of the microbubbles in the FUS bean, and to determine the type of cavitation, i.e., the activation of bubbles in an acoustic field, during …

Development of an Injectable Hydrogel Platform to Capture and Eradicate Glioblastoma Cells with Chemical and Physical Stimuli
… hydrogel was acoustically active to generate a stable cavitation bubble cloud with histotripsy treatment for ablation of entrapped red blood cells with well-defined, uniform lesion areas. Overall, the results from this research demonstrate this injectable hydrogel is a promising platform to …

On the fundamental mechanisms & optimisation of ultrasonic assisted liquid phase exfoliation of two dimensional nanomaterials
The application of ultrasound and acoustic cavitation in liquid exfoliation of bulk layered materials is a widely used method. Ultrasonic assisted liquid phase exfoliation (ULPE) is a promising procedure for the large scale production of two dimensional (2D) materials. As of this date, toxic …
