<P>PROBLEM TO BE SOLVED: To provide an improved method for drive control of a magnetic resonance system and its befitting control apparatus. <P>SOLUTION: In a test phase before magnetic resonance measurement, a test high-frequency pulse having plural parallel individual high-frequency pulses is transmitted by a transmitting antenna device via various high-frequency transmitting channels. Here, the test high-frequency pulse forms a field distribution which is substantially the same as an excited high-frequency pulse transmitted during the subsequent magnetic resonance measurement with a comparatively small transmitting output, and the high-frequency field formed by the test high-frequency pulse is measured in at least one area of a local coil device, and the prospective high-frequency filed value is calculated in the local coil apparatus based on the measured high-frequency field during the subsequent magnetic resonance measurement, and the magnetic resonance system is drive-controlled with consideration for the high-frequency field value during the subsequent magnetic resonance measurement. <P>COPYRIGHT: (C)2013,JPO&INPIT |
