CLI Commands

Cardiotensor provides powerful features for analyzing 3D cardiac imaging data, from processing imaging volumes and calculating orientation to managing large-scale projects with support for multiple configurations and platforms.

Orientation Computation

Compute myocyte orientation from a 3D volume using a configuration file.

  • cardio-tensor Computes structure tensor, helix/transverse angle, FA, and eigenvectors.

See the example to get started.

Transmural Analysis

Plot angle profiles across the heart wall using an interactive GUI.

  • cardio-analysis Define transmural lines, adjust sampling, and export results.

See the example for details.

3D Visualization

Visualize results in 3D using vector fields and streamlines.

Note

To use these modules, you must first compute and save the eigenvector field by setting WRITE_VECTORS=True in the configuration file before running the structure tensor calculation.

  • cardio-visualize-vector Render vector fields using Fury. Optionally export to ParaView (VTK format).

  • cardio-generate-streamlines Generate streamlines from the vector field. Outputs .npz files compatible with Amira.

  • cardio-visualize-streamlines Visualize streamlines in 3D using Fury. Can also export to ParaView.

See the example for usage.
