Seminar DCSY - Treeby B.E.: Modelling biomedical ultrasound
Astract: Modelling the propagation of ultrasound waves in the human body has many applications, from reconstructing images to planning treatments using ultrasound therapy. In this talk, I will discuss the steps required in developing a numerical model, including forming equations that capture the physics of interest, applying appropriate numerical methods to solve these equations, developing computer codes for different computer architectures, and performing experimental validation. To create useful models, each of these steps and the corresponding constraints must be carefully considered. Using these steps as a blue-print, I will then discuss the development of k-Wave, a MATLAB toolbox that we have developed for modelling ultrasound waves in the body.
Biography: I am an EPSRC Early Career Fellow and lead the UCL Biomedical Ultrasound Group with Dr Ben Cox. My research sits at the interface between physical acoustics, biomedical ultrasound, numerical methods, and high performance computing. In particular, I am interested in developing fast and accurate models of how ultrasound waves travel through the human body. This involves studying many interesting acoustic phenomena from a physical perspective, and then devising novel ways in which these can be captured by a numerical model. Much of my work has been released as an open-source acoustics toolbox for MATLAB called k-Wave. These models have important applications in both ultrasound and photoacoustic imaging, and dosimetry and treatment planning for ultrasound therapy. I work with a multidisciplinary team, and currently collaborate with researchers from a range of backgrounds, including mathematics, physics, computer science, radiology, haematology, oncology, and neurology.
