To simulate and plan robotic procedures, we propose methods for generating patient specific anatomically correct 3D and 3D+Time models.
Our inter-model approach combines information from different imaging modalities: CT, MRI and X-ray coronarography.

Our methods include:

    - Semi-interactive and automatic segmentation of 2D arteries centerlines

    - Stereoscopic reconstruction of 3D arteries centerlines

    - Fitting of dynamic model of coronary arteries
    - Tomographic reconstruction of coronary arteries

    - Fusion of angiography and CT/MRI data

For example, dynamic models of the coronary trees can be reconstructed from biplane angiogram projections or from rotational angiogram projections.
