From medical imaging to CFD

The object of this talk is to introduce the pipeline of studying physiological flows. We start by highlighting the pipeline of going from a stack of medical images to numerical simulation. Difficulties are identified and an example demonstrating the importance of accurate virtual model boundaries is presented. Morphological variations between different patients and their correlation to disease-associated fluid mechanics properties is alsointroduced. However identifying these fluid mechanics properties is also non-trivial since the full physiological complexity and responses are too complex. The idea is to identify flow characteristics and as well as when these become abnormal. Results for both a peripheral bypass graft and nasal cavity are presented.
