Universal pulses: A new concept for calibration‐free parallel transmission

Purpose A calibration‐free parallel transmission method is investigated to mitigate the radiofrequency (RF) field inhomogeneity problem in brain imaging at 7 Tesla (T). Theory and Methods Six volunteers were scanned to build a representative database of RF and static field maps at 7T. Small‐tip‐angl...
