SAR-optimized control of a coil array

A driving method of coils (6) of a transmit array (4) and a gradient magnet system (3) of a magnetic resonance system, - wherein a control device (7) of the magnetic resonance system, each of the coils (6) of the transmit array (4) and the gradient (3) corresponding to each excitation pulse (P ') drives, - wherein, due to the driving of the coil (6) of the transmit array (4) and of the gradient magnet (3) in an excitation volume (2) of the magnetic resonance system magnetization is generated corresponding to the respective excitation pulse (P ') having a first Istinhomogenitat (I2) . - wherein the control means (7) to the respective excitation pulse (P ') based on a respective start pulse (P) and one in the excitation volume (2) of the magnetic resonance system maximum acceptable inhomogeneity (I *) is determined, - wherein (P) of the respective start pulse has a total duration (T ') and in the case that the control means (7) drives the coil (6) of the transmit array (4) and the gradient (3) corresponding to the respective start pulse (P) , in the excitation volume (2) of the magnetic resonance system magnetization is generated, the second ...
