Synopsis

Keywords: Arrhythmia, MR-Guided Interventions, Real-time imagingWe propose Cardiac Library Based Real-time Imaging (CALIBRI), which allows the use of the same data for both catheter tracking and real-time visualization of cardiac motion states. This is achieved by matching the acquired k-lines with a library of pre-acquired cardio/respiratory gated 3D CINE data. In this study, we implemented our novel method on a 3T MRI system and showed the feasibility of this approach in multiple healthy volunteers.
