Abstract:

BACKGROUND: With the development of computer technology, blood vessels virtual reality becomes possible.
OBJECTIVE: To construct a digital finite element model of the lower limb artery based on the CT sectional images for fluid dynamics simulation.
METHODS: DICOM images were harvested from patients with narrow artery CTA to build a three-dimensional model in MIMICS14.0. Then, the finite element model was obtained in ANSYS11.0, for analysis of the real conditions of fluid flow.
RESULTS AND CONCLUSION: A three-dimensional model of local stenosis vessel in MIMICS14.0 software. Then, the finite element model of blood vessels was obtained in ANSYS workbench, with 7 335 model nodes and 43 415 units. Finite element analysis was applied to obtain a series of visualized computational fluid data. We could the visual graphic of the flow velocity variations, pressure variations, blood flow path and Wall shear, and establish the required three-dimensional finite element model.
