Microbubbles are of great interest both for ultrasound imaging and ultrasound-assisted therapy due to their nonlinear scattering, which is enhanced by the viscoelastic shell. A full characterization this response therefore crucial fully exploit potential. Current microbubble techniques rely on assumptions regarding shell rheology. Here, a stress-strain method proposed characterize shells single microbubbles with minimal underlying assumptions, mainly entail separable viscous elastic...
Ultrafast plane-wave ultrasound imaging is a versatile tool which has become increasingly relevant for blood flow using speckle tracking, but suffers from low signal-to-noise ratio (SNR). Cascaded dual-polarity waves (CDW) can improve the SNR by transmitting pulse trains, are subsequently decoded to recover resolution. However, current decoding method (in time domain) requires set of two acquisitions, introduces motion artifacts that result in incorrect tracking at high velocities. Here, we...
Microbubble contrast agents hold great promise for drug delivery applications with ultrasound. Encapsulating drugs in nanoparticles reduces systemic toxicity and increases circulation time of the drugs. In a novel approach to microbubble-assisted delivery, are incorporated or on microbubble shells, enabling local triggered release nanoparticle payload A thorough understanding mechanisms within vast ultrasound parameter space is crucial efficient controlled release. This set presented...
The interface of a soft hydrogel is easily deformed when it in contact with particles, droplets or cells. Here we compute the intricate shapes menisci due to indentation point particles. analysis based on free energy formulation, by which also assess interaction laws between neighbouring particles interfaces, similar "Cheerios effect". It shown how meniscus formed around results from competition surface tension, elasticity and hydrostatic pressure inside gel. We provide detailed overview...
