Real-Time Virtual Endoscopy for MR-Guided Aortic Interventions
Klaus J. Kirchberg, Andreas Wimmer, Cristian Lorenz · 2006
Moving from traditional diagnostic MR imaging to MR-guided interventions requires not only specialized pulse sequences, but also novel means of visualization and navigation. Current real-time MR visualization techniques include 3D views of single or multiple 2D slices, projection images and volume rendering (alpha blending/MIP mapping) [1]. For aortic interventions, e.g. stent placement, it would be beneficial for the physician to be able to appreciate the entire area of interest, as opposed to one slice or projection. In addition to giving the physician a better understanding of the instrument position, this technique could also help to detect
