Venue: EPSA seminar room - Hawken building S214.
Host: Prof Stuart Crozier
Abstract:Today, numerical simulation has become ubiquitous, and there is no
exception to biomedical engineering (BME), a discipline concerned
with the application of science and technology (devices and methods)
to biology and medicine. Within this very diverse area, numerical
tools are particularly useful to the medical instrumentation
simulation and biological modelling.
The subject of this seminar is software design for numerical
simulation in BME. Here, the speaker will restrict herself to two
typical problems she has met: one is magnetic resonance engineering,
the other is computational cardiology, and both are centred on the
electromagnetic field calculation.
Over the last decade, as MRI moves to higher field strengths in
search of better SNR and improved image resolution, the study of the
interactions of electromagnetic fields with sampled human tissue
becomes increasingly critical. This project aims to provide a
dedicated Finite Difference, Time Domain (FDTD) simulator for
electromagnetic analysis and design in MRI, and the focused
application will be the analysis/design of high-frequency RF coil
system.
Heart modelling is an important area in BME, and another topic is to
develop a beating heart model for the simulation of cardiac
electrical activity and the subsequent computation of the
electrocardiogram (ECG) and helps the cardiac source imaging
(inverse problem). Incorporating cardiac motion measured using MRI
technology will be emphasized as the influence of the myocardial
wall movement on the surface potentials is investigated little in
the literature.
Biography:Qing is currently undertaking a PhD in the School of Information
Technology and Electrical Engineering (ITEE) at the University of
Queensland. Her supervisors are Professor Stuart Crozier and
Prof. Ling Xia (Zhejiang University, China). She has graduated with
a master degree in Information Technology from the University of
Queensland in 2003.
