Real-Time Virtual Endoscopy for MR-Guided Aortic Interventions

Moving from traditional diagnostic MR imaging to MR-guided interventions requires not only specialized pulse sequences, but also novel means of visualization and navigation. We propose an interactive, segmentation-based approach to render a virtual endoscopic view of the aorta in real-time. A 3D/4D model is generated and then continuously updated based on the subsequently acquired MR images. The model construction, updating and rendering is integrated in a graphical scanner control and automation framework.
