This repository provides a helper class for working with the cardiac meshes produced by the CardioX pipeline. This code was tested successfully on bi-ventricular meshes produced by the SpASM method as well as the current full-heart model.

4. TO DO

The code has been tested using the following versions:

• trimesh==3.9.15
• vtk==9.0.1
• numpy==1.17.4
• pyglet==1.5.18
• meshio==2.3.0
• numpy-stl==2.17.1 (for working with volumetric meshes)

You can add this repository as a submodule to your main repository, under the utils folder (or similar).

This repo implements three classes:

• Cardiac3DMesh: represents a single cardiac mesh or point cloud.
• Cardiac4DMesh: represents a collection of cardiac meshes for one individual, across the cardiac cycle.
• CardiacMeshPopulation: represents a population of cardiac meshes (either 3D or 4D), i.e. meshes for different individuals in a population.

from CardioMesh.CardiacMesh import Cardiac3DMesh

vtk_path = "full_heart_model.vtk"
mesh = Cardiac3DMesh(vtk_path)
mesh.show()

# This follows from the previous code snippet
# LV mesh
lv_mesh = mesh["LV"]

# LV & RV mesh
lvrv_mesh = mesh["LV", "RV"]

lvrv_mesh.show()
