Abstract:Toward an establishment of basis for medical applications such as ultrasound diagnosis, the mathematical model for the propagation of ultrasound (or pressure waves) in a liquid containing microbubbles encapsulated by a viscoelastic shell is constructed from the theoretical viewpoint. For simplicity, the bubbles do not coalesce, break up, appear, and disappear; the bubbles are spherical, and these oscillations are spherically symmetric; the viscosity of gas inside the bubbles and the thermal conductivities of b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
