Abstract:High intensity focused ultrasound (HIFU) therapy has become a new way in the treatment of tumors due to its noninvasive advantage. However, as for the HIFU nonlinear propagation and temperature field in human body in relation to practice HIFU therapy, there are few studies on numerical simulation based on models conforming to practical situation. In this study, we report a numerical method of finite difference time domain (FDTD) for analyzing HIFU temperature field in human body tissues and demonstrate it thro… 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.
