A new method of mapping the transmit B1 field is introduced that is capable of rapidly producing 3D B1 maps at low flip angles without relying on the double angle assumption. It is based on the accelerated 3D Look-Locker sequence and has been compared to both the standard double angle method as well as a double angle implementation of the 3D Look-Locker sequence.
