Transmit and receive RF fields determination from a single low‐tip‐angle gradient‐echo scan by scaling of SVD data

A new method, called Transmit and Receive Patterns from Low‐Tip‐angle gradient‐Echo Images (TRIPLET), is described which simultaneously maps the B1+ and B1− fields of a transmit/receive radiofrequency coil array. The input data are low‐tip‐angle gradient‐echo images, which can be acquired in a relatively short scanning time.
