SOFTWARE TOOLS FOR IMAGE-BASED MODELING OF FLUID-SOLID INTERACTION IN CORONARY ARTERIES FUSING IVUS AND ANGIOGRAPHY MODALITIES

A method for three-dimensional modeling of coronary arteries fusing X-ray angiography and intra vascular ultrasound (IVUS) imaging modalities is presented. A 3-D IVUS catheter path is reconstructed from a pair of biplane angio images taken from same cardiac moment. Vessel wall is segmented from previously image-based ECG gated IVUS images and fused with catheter path to retrieve volumetric mesh for fluid-solid interaction simulation using finite element method.
