Ultrasonic irrigation of the root canal can be performed with or without simultaneous
ultrasonic instrumentation. When canal shaping is not undertaken the term passive ultrasonic …

Ultrasound contrast agents are valuable in diagnostic ultrasound imaging, and they increasingly
show potential for drug delivery. This review focuses on the acoustic behavior of flexible-…

… kg/m 3 , and a surface tension γ of 0.072 N/m, we find τ b = 10 μs, which translates to a
frame rate of 500 kfps. The diminutive Rayleigh jet of Fig. 11b has a radius of 1.25 μm, and the …

We present a model applicable to ultrasound contrast agent bubbles that takes into account
the physical properties of a lipid monolayer coating on a gas microbubble. Three parameters …

… of the bubble as high as 32 m/s, whereas the bubble expands longitudinally with a speed
of 9 m/s. This indicates a flow with a speed v max on the order of 25 m/s. This high water jet …

Ultrasound contrast microbubbles have the ability to enhance endothelial cell permeability
and thus may be used as a new way to deliver drugs. It facilitates the transfer of extracellular …

The fluid dynamic interaction of cavitation bubbles with adherent cells on a substrate is
experimentally investigated. We find that the nonspherical collapse of bubbles near to the …

Functional MRI (fMRI) generally employs gradient‐echo echo‐planar imaging (GE‐EPI) to
measure blood oxygen level‐dependent (BOLD) signal changes that result from changes in …

A new optical characterization of the behavior of single ultrasound contrast bubbles is
presented. The method consists of insonifying individual bubbles several times successively …

Aim To test ex vivo the efficiency of laser‐activated irrigation in removing dentine debris
from the apical part of the root canal and to visualize in vitro the fluid dynamics during the …
