Patent ID: 7550973

Claim:
A method for locally manipulating a B 1 field in a first region of an examination subject in an examination volume of a magnetic resonance system, said method comprising the steps of: in an adjustment measurement, measuring a B 1 measurement value in sub-volume of the examination subject that is representative of the B 1 field in the sub-volume, and integrating said B 1 measurement value over said sub-volume; from the B 1 measurement value integrated over said sub-volume, automatically determining radio-frequency signal parameters for a subsequent diagnostic magnetic resonance measurement of the examination subject to manipulate said B 1 field in said first volume during said diagnostic magnetic resonance measurement; and while measuring said B 1 measurement value in said adjustment measurement, influencing the B 1 field in a second region in the examination subject counter to the manipulation in said first region by activating an auxiliary coil element located in said second region or at said second region.
