- Title
- Predicting and controlling histotripsy bubble clouds
- Plain
- Very short, very intense sound pulses tear tissue apart mechanically by creating clouds of bubbles. Where and when those clouds form is only partly predictable.
- Precise
- Predict the threshold and spatial extent of histotripsy bubble-cloud formation from the incident pressure waveform, with peak negative pressures of $10^8\text{ to }3 x 10^8\,\mathrm{dyn}/\mathrm{cm}^2$ and microsecond pulses, including nucleus distribution in tissue, shock scattering from earlier bubbles, and tissue mechanical properties. An answer is a predictive model giving the treated volume boundary to within $1\,\mathrm{mm}$.
- Settled by
- High-speed imaging and acoustic measurement of cloud formation across pressure and tissue type, compared with the model prediction and the resulting lesion.
