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)
• pydicom
• pyvista
