Bubble dynamics and size distributions during focused ultrasound insonation.
The deposition of ultrasonic energy in tissue can cause tissue damage due to local heating. For pressures above a critical threshold, cavitation will occur, inducing a much larger thermal energy deposition in a local region. The present work develops a nonlinear bubble dynamics model to numerically investigate bubble oscillations and bubble-enhanced heating during focused ultrasound (HIFU) inso...
متن کاملDependence of bubble size and peak rarefractional pressure on maximum bubble response during therapeutic ultrasound histotripsy
Medical ultrasound has shown great potential as a minimally invasive therapy technique. It can be used in areas such as histotripsy, thermal ablation, and administering medication. The success of these therapies is improved by the cavitation of microbubbles. This study evaluated the effect of varying the pressure amplitude on cavitation resonance frequency and the corresponding bubble size at t...
متن کاملLorenz Curves, Size Classification, and Dimensions of Bubble Size Distributions
Lorenz curves of bubble size distributions and their Gini coefficients characterize demixing processes. Through a systematic size classification, bubble size histograms are generated and investigated concerning their statistical entropy. It turns out that the temporal development of the entropy is preserved although characteristics of the histograms like number of size classes and modality are ...
متن کاملDetermination of Bubble Size Distributions in Bubble Columns Using LDA
A new method is developed for the determination of bubble size distributions from experimental laser Doppler anemometry (LDA) data through simultaneous measurement of only two orthogonal velocity components and the intermittent time gaps arising out of bubbles passing through the measurement point. An experimentally verifiable assumption of axisymmetry allowed the calculation of the three-dimen...
متن کاملCavitation-induced damage of soft materials by focused ultrasound bursts: A fracture-based bubble dynamics model.
A generalized Rayleigh-Plesset-type bubble dynamics model with a damage mechanism is developed for cavitation and damage of soft materials by focused ultrasound bursts. This study is linked to recent experimental observations in tissue-mimicking polyacrylamide and agar gel phantoms subjected to bursts of a kind being considered specifically for lithotripsy. These show bubble activation at multi...
