74 results about "Finite element method analysis" patented technology

The invention discloses a three-dimensional visualization method based on the processing result of finite-element analysis, belonging to the technical field of three-dimensional visualization display. The method comprises the following steps: disintegrating generated grid cell cubes, getting rid of internal public data surfaces and generating an external contour surface aggregate; carrying out coplane grouping on the external contour surface aggregate to obtain a coplanar cell data surface aggregate CoMAP; disintegrating all cell data surfaces in each CoMAP into an independent cell data side, getting rid of all internal common sides to obtain a coplane contour line aggregate; carrying out contour line grouping on all coplane contour line aggregates and dividing all sides forming closed contour lines into a group; finally, generating an independent topological surface according to each group of closed contour lines and judging whether the topological surface is a hole or a surface, carrying out Boole summation operation on all non-hole surfaces and Boole subtracting operation on holes to generate a three-dimensional model. The method disclosed by the invention provides an approach through which the finite-element analysis technique and the virtual reality technique can be combined.

Systems and methods provide a novel computational approach to planning the endovascular treatment of cardiovascular diseases. In particular, the invention simulates medical device deployment and hemodynamic outcomes using a virtual patient-specific anatomical model of the area to be treated, high-fidelity finite element medical device models and computational fluid dynamics (CFD). In an embodiment, the described approach investigates the effects of coil packing density, coil shape, aneurysmal neck size and parent vessel flow rate on aneurysmal hemodynamics. A processor may receive patient clinical data used to construct the relevant anatomical structure model. The processor may access medical device models constructed using finite element analysis and three dimensional beam analysis, and simulates the deployment of selected medical devices in the anatomical structure model. The selected medical device models and the anatomical structure model mesh, allowing the processor to simulate hemodynamic outcomes using computational fluid dynamics.
