Image shows how a cancer cell flows over the white blood cell without any bond interactions or deformation. Solid walls (including the cells) are colored by flow velocity and the lines are velocity contours.

Recent advances in medical imaging technology have allowed the acquisition of high-resolution, transient, three-dimensional images of blood flows within the human circulatory system. It is only natural that EnSight, widely used for visualizing blood flows computed in CFD simulations, be applied to the visualization of such complex medical imaging data providing compressive anatomical (blood vessel) and functional (blood flow) coverage of an entire organ of interest. 

CEI's medical imaging page, click here, includes a brief summary of the method, recent results and several references to articles in medical literature on this unique application of EnSight in the medical field. CEI has established a partnership with the Department of Diagnostic Radiology, Medical Physics at the University Hospital of Freiburg, a leading user of EnSight for flow sensitive 4D MR imaging, to aid others interested in using the software.

Animation shows stent/balloon inflation dynamics and the impact that this has on peak arterial stresses.  During inflation, the stent has a tendency to flare at the ends due to the balloon overhang.  Increased overhang results in increased stent endflare and peak arterial stresses.  This, in turn, can increase the chances of restenosis (uncontrolled cell growth leading to the artery clogging back up).  The model is currently being adjusted to test high-pressure and high-resistance lesions.
