Query: Simulation of bifurcated stent grafts to treat abdominal aortic
  aneurysms (AAA)   In this paper a method is introduced, to visualize bifurcated stent grafts in
CT-Data. The aim is to improve therapy planning for minimal invasive treatment
of abdominal aortic aneurysms (AAA). Due to precise measurement of the
abdominal aortic aneurysm and exact simulation of the bifurcated stent graft,
physicians are supported in choosing a suitable stent prior to an intervention.
The presented method can be used to measure the dimensions of the abdominal
aortic aneurysm as well as simulate a bifurcated stent graft. Both of these
procedures are based on a preceding segmentation and skeletonization of the
aortic, right and left iliac. Using these centerlines (aortic, right and left
iliac) a bifurcated initial stent is constructed. Through the implementation of
an ACM method the initial stent is fit iteratively to the vessel walls - due to
the influence of external forces (distance- as well as balloonforce). Following
the fitting process, the crucial values for choosing a bifurcated stent graft
are measured, e.g. aortic diameter, right and left common iliac diameter,
minimum diameter of distal neck. The selected stent is then simulated to the
CT-Data - starting with the initial stent. It hereby becomes apparent if the
dimensions of the bifurcated stent graft are exact, i.e. the fitting to the
arteries was done properly and no ostium was covered.
