Abstract:
1. A method for assessment of virtual stent implantation in an aortic aneurysm, comprising: generating a patient-specific 4D anatomical model of the aorta from 4D medical imaging data; adjusting a model representing mechanical properties of the aorta wall to reflect changes to the mechanical properties of the aorta wall due to aneurysm growth at a plurality of time stages, resulting is respective re-modeled mechanical properties of the aorta wall at each of the plurality of time stages; generating a plurality of stable deformation configurations of the aorta, wherein each of the plurality of stable deformation configurations of the aorta is generated for a respective one of the plurality of time stages by performing a respective fluid structure interaction (FSI) simulation using the patient-specific 4D anatomical model at the respective one of the plurality time stages based on the respective re-modeled mechanical properties of the aorta wall at the respective one of the plurality of time stages; performing a respective virtual stent implantation for each of the plurality of stable deformation configurations of the aorta; and performing FSI simulations for each virtual stent implantation.
