In a method for generation of magnetic resonance exposures and a control
device for a magnetic resonance tomography apparatus, a number of coils
are available in the apparatus, the coils being are positioned at various
locations relative to the examination subject. Initially a
radio-frequency signal is emitted and a spatially-resolved signal
intensity distribution is measured with at least one or some of the
available coils. An automatic determination of a three-dimensional
exposure profile of the appertaining coils is made based on the received
signals. A selection of one or more of the appertaining coils for a
subsequent magnetic resonance measurement is made on the basis of the
determined exposure profiles of the coils as well as the measurement
region to be acquired in the magnetic resonance measurement.
