Abstract
A method for computing patient-specific hemodynamics. The method includes receiving three dimensional imaging data of a patent, extracting anatomical data from the three dimensional imaging data, calculating velocity and pressure fields corresponding to the extracted anatomical data, and calculating displacement and velocity of extracted solid particles corresponding to the anatomical data. The anatomical data comprises an anatomical boundary.
Claims12
A method of non-invasively quantifying in vivo blood flow and flow-artery interaction in an artery, comprising:
- receiving image data of anatomical features of the artery;
- processing the image data on a GPU parallel-computation framework employing mesoscale models;
- and
- causing display of information representing the flow-artery interaction;
- wherein processing comprises
- using a simplified lattice Boltzmann method (“SLBM”) to model anatomical segmentation of the artery,
- using a volumetric lattice Boltzmann method (“VLBM”) to model fluid dynamics of the flow-artery interaction,
- using a lattice spring method (“LSM”) to model structure mechanics of the flow-artery interaction, and
- using the SLBM to model interface tracking of the flow-artery interaction.
