A 700 kHz histotripsy array is used to generate repeated cavitation events in agarose, gelatin, and polyacrylamide hydrogels. High-speed optical imaging, a broadband hydrophone, and the narrow-band receive elements of the histotripsy array are used t

A novel method for fabricating a modular, kerf-minimizing histotripsy phased array was developed and tested. The method utilizes arbitrarily shaped elements, 3-D printing, water jet cutting, and a thin, 125- [Formula: see text] electrically insulatin

Histotripsy has been previously applied to target various cranial locations in vitro through an excised human skull. Recently, a transcranial magnetic resonance (MR)-guided histotripsy (tcMRgHt) system was developed, enabling pre-clinical investigati

Histotripsy is a method of ultrasound therapy using very intense, focused sound fields to fragment tissue causing controlled and localized necrosis principally through mechanical actions of cavitation. Highly specialized instrumentation (transducers

The nucleation and collapse of cavitation generated during histotripsy results in point-like emissions of shockwaves. Owing to the short duration acoustic pulses utilized during histotripsy the acoustic background from pulse reflections off interveni

Acoustic cavitation emission (ACE)/shockwave signals generated by cavitation during histotripsy have been demonstrated to undergo characteristic changes correlated with the level of damage generated in select target media following repeated cavitatio

Phase aberration by heterogeneous soft tissues decreases the focusing quality of transabdominal histotripsy, thereby increasing the energy required to generate cavitation for therapy and elevating the risk of unsafe tissue heating. In vitro studies h

This paper describes a method for acquiring high temporal and spatial resolution images of cavitation events using a multiple-flash-per-camera-exposure imaging technique. A primary challenge associated with imaging cavitation is that the velocity of

Results from neuronavigation-guided transcranial histotripsy treatments in cadaveric models are presented. Histotripsy treatments were delivered transcranially to the brains of 3 cadavers (
