In this work, we present an integrated system that incorporates active device tracking implemented in an interactive real-time sequence as well as a graphical interface for real-time catheter visualization and navigation. The system supports tracking and visualization of multiple catheters and several options for automatically updating imaging planes. The tracking provided robust catheter location accuracy, and the visualization of the catheters provided the users with an environment similar as with X-ray fluoroscopy guided procedures. The system is especially suitable for MR guided intravascular interventions in which real-time catheter tracking and visualization for navigation is mandatory.
