Claim One:
1. A magnetic resonance system comprising: a main magnet ( 12 ) which generates a substantially uniform main magnetic field in an examination region; a multi-channel radio frequency coil assembly ( 16 ) including a plurality of coil elements ( 16 1 , 16 2 ,. .. 16 n ) and a transmitter array ( 20 ) including a plurality of transmitters ( 20 1 , 20 2 ,. .. 20 n ) which induces magnetic resonance in selected dipoles of a subject in the examination region; a receive array ( 22 ) which receives magnetic resonance signals; a specific energy absorption rate calculation processor ( 36 ) that calculates a specific energy absorption rate for the multi-channel radio frequency coil assembly ( 16 ); and a sequence controller ( 24 ) that reconfigures RF excitation pulses that account for the local specific energy absorption rate hotspots.
