Abstract:
1. A method for controlling a magnetic resonance system to implement a magnetic resonance measurement of at least one specific volume region within an examination subject, said magnetic resonance system comprising a radio-frequency antenna structure with a plurality of individually controllable transmission channels that are controlled to radiate a radio-frequency field into the specific volume region, said method comprising the steps of: providing a limited number of different antenna control parameter sets that are respectively associated with different examination situation classes that are respectively defined by respective examination situation parameters, each antenna parameter control set for an examination class comprising, for each of said transmission channels, a channel value or a channel value combination that defines a relative amplitude and a relative phase of a radio-frequency signal emitted by that transmission channel; identifying current examination situation parameter values for a current magnetic resonance magnetic resonance measurement to be implemented using said magnetic resonant system; selecting one of said examination situation classes dependent on the detected current examination situation parameter values; and implementing said magnetic resonance measurement using an antenna control parameter set that is associated with the selected examination situation class by feeding radio-frequency signals in parallel from said transmission channels into said radio-frequency antenna structure with respective amplitudes and phases in the respective channels according to the antenna control parameter set that is associated with the selected examination situation class.
