The interaction of microbubbles with high intensity pulsed ultrasound
High intensity pulsed ultrasound when interacting with microbubble contrast agents is potentially useful for biomedical applications such as drug delivery, cancer treatment and tissue ablation. To establish a fundamental understanding of the interaction between a microbubble with a sound wave, numerical simulations are performed using the Boundary Element Method (BEM). Bubble dynamics in terms ...
متن کاملInteraction of microbubbles with high intensity pulsed ultrasound.
High intensity pulsed ultrasound, interacting with microbubble contrast agents, is potentially useful for drug delivery, cancer treatment, and tissue ablation, among other applications. To establish the fundamental understanding on the interaction of a microbubble (in an infinite volume of water) with an ultrasound pressure field, a numerical study is performed using the boundary element method...
متن کاملUltrasound Imaging using the Low-Frequency Response of Microbubbles
When microbubbles are excited by two frequency signals, a nonlinear response signal may occur at the difference frequency. As these two frequencies are made close, this nonlinear response will reside at lowfrequency region. We have derived a theory for the weak short-pulse response based on a two-frequency approximation, which provides the pressure and the bandwidth dependence properties of the...
متن کاملLipid Coated Microbubbles and Low Intensity Pulsed Ultrasound Enhance Chondrogenesis of Human Mesenchymal Stem Cells in 3D Printed Scaffolds
Lipid-coated microbubbles are used to enhance ultrasound imaging and drug delivery. Here we apply these microbubbles along with low intensity pulsed ultrasound (LIPUS) for the first time to enhance proliferation and chondrogenic differentiation of human mesenchymal stem cells (hMSCs) in a 3D printed poly-(ethylene glycol)-diacrylate (PEG-DA) hydrogel scaffold. The hMSC proliferation increased u...
متن کاملLow-frequency low energy ultrasound combined with microbubbles induces distinct apoptosis of A7r5 cells.
The present study aimed to investigate whether low frequency low energy ultrasound combined with microbubbles induces apoptotic cell death of A7r5 rat aortic vascular smooth muscle cells, and to identify the possible mechanisms underlying this effect. Ultrasonic waves (45 kHz with 0.3 Wcm2 of intensity for 0, 10, 20 and 30 sec) were used together with different dosages of SonoVue™ microbubbles ...
