Features
The main provided functionalities enable to:
- read 4D flow dicom files and generate .vtk files that can be visualized in Paraview;
- extract velocity profiles from 4D flow and map them to the inlet of a target model;
- write boundary conditions files for multiple CFD software, including Fluent, CFX, Star-CCM+, OpenFoam, SimVascular
Installation
To run the scripts you need a python interpreter. The use of a conda environment is strongly recommended.
Dependencies
- vmtk (optional, only required for centerline extraction)
