    Numerical Modeling of Medical Ultrasound

    In the last two decades, we have witnessed enormous 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. To truly understand, design and improve HIFU-based technologies and eventually adopt them clinically, it is vital to have a versatile and fast, yet accurate ultrasound numerical model. Although there are many ultrasound 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. In this talk, 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, therefore filling the gap between these two critical requirements. I will focus on both the theoretical development and the practical applications of the numerical algorithm. I will also introduce our ongoing NIH-funded project that aims to develop an open-source toolbox for modeling medical ultrasound.
