Abstract: A breast coil for a magnetic resonance tomography device for the production of magnetic resonance recordings of female breasts includes a coil housing having a breast recess to accommodate a breast and a number of coil elements. At least one of the coil elements forms an HF correction coil element and has a circuit arrangement to switch over the HF correction coil element between an HF correction mode of operation and another mode of operation. The HF correction coil element is constructed such that in the HF correction mode of operation, the HF correction coil element resonates passively with a B1 field emitted by a transmission antenna arrangement of the magnetic resonance tomography device, and influences a local B1 field distribution during a magnetic resonance recording.

Abstract: A method for the control of a magnetic resonance system is provided. In a test phase before a magnetic resonance measurement, a test high-frequency pulse with several parallel individual high-frequency pulses is transmitted with a transmitter antenna arrangement over various different high-frequency transmitter channels. At lower transmitter power, the test high-frequency pulse generates essentially the same field distribution as an excitation high-frequency pulse to be transmitted during a subsequent magnetic resonance measurement. A high-frequency field generated by this test high-frequency pulse is measured in at least one area of a local pulse arrangement, and on the basis of the high-frequency field measured, a high-frequency field value that is to be anticipated at the local coil arrangement during the subsequent magnetic resonance measurement is determined. The control of the magnetic resonance system during a later magnetic resonance measurement includes taking the high-frequency field value into account.
