Abstract:
1. A magnetic resonance method comprising the acts of: performing a plurality of magnetic resonance excitation operations each using a different sub-set of a set of radio frequency transmit coils that are physically bound together as a unit, each sub-set including more than one radio frequency transmit coil; acquiring magnetic resonance data responsive to each said magnetic resonance excitation operation; computing a B1 or flip angle map for each radio frequency transmit coil of the set of radio frequency transmit coils based on the acquired magnetic resonance data; and storing the B1 or flip angle map in a memory, wherein the computing act includes performing mapping sequences using the different sub sets and wherein each of the different sub sets includes all but one different radio frequency transmit coil of the set of radio frequency transmit coils that are physically bound together as a unit.
