Numerical Modeling of Medical Ultrasound
Abstract
In the last two decades, we have witnessed substantial development in high intensity focused ultrasound (HIFU) for treating a
broad spectrum of diseases and medical conditions. As a non invasive surgical modality that can reach deep tissue, HIFU has
the potential to revolutionize therapy. Although there are many numerical models available, none can currently achieve both
efficient and sufficiently accurate simulations for acoustic wave propagation in large scale, heterogeneous biological media.
Existing numerical models face two enduring dilemmas: they are either very efficient but not accurate due to invalid
approximations, or they are very accurate but computationally time consuming and therefore impractical in many cases. I will
discuss our effort throughout the past 10 years in developing new numerical models for HIFU, that aims to establish a
balance between accuracy and computational efficiency. I will focus on both the theoretical development and the practical
applications of the numerical algorithm. I will also introduce our NIH funded project that aims to develop an open source
toolbox for modeling medical ultrasound (https://m-sound.github.io/mSOUND/home).
