VR-Enabled Visualization of Cardiac Motion based on 4D CT Segmentation 1: Politecnico di Milano; 2: Università degli Studi di Cagliari This work presents an integrated workflow for whole-heart segmentation, animation, and visualization from 4D CT data. It combines segmentation, mesh post-processing, frame-based animation, and immersive visualization within a single web-based framework. 20 CT volumes, each corresponding to a different phase of the cardiac cycle, were segmented into the main cardiac structures using a hybrid manual and semi-automatic approach. The resulting models were refined to correct defects, discontinuities, and surface irregularities while preserving consistency across frames. Cardiac motion was reconstructed through a frame-based animation strategy, where each mesh represents a discrete temporal state of the heart. This approach avoids complex deformation methods while preserving anatomical fidelity and real-time performance.The visualization system was implemented using Babylon.js and WebXR, enabling interactive exploration of the animated model on both desktop systems and virtual reality devices. The proposed framework supports the inspection of heart morphology and its temporal evolution throughout the cardiac cycle through multiple visualization modalities, thereby enabling possible applications in diagnosis, treatment planning, and patient-specific analysis. | |
