A dynamic coil selection algorithm is presented to reduce the reconstruction time during real time parallel MRI. Coil data are dynamically selected for reconstruction based on their relative distance to the current imaging slice. In an animal experiment this technique was combined with parallel image acquisition and active catheter tracking. An active catheter was imaged during insertion into the abdominal aorta and the heart at a frame rate of 4 images/s.
