The determination of B1+ in moving organs, in particular in the heart, is a largely unmet problem. Most B1+ mapping sequences are too long and/or cannot be acquired in a (double-) triggered mode. We developed and validated a single-voxel PRESS sequence based on the Bloch-Siegert shift which is largely immune against effects of motion and which can additionally be double-triggered. Measurements in vitro and in the human heart show an excellent performance of the sequence.
