Abstract:
1. A method for adjusting the field strength of radio-frequency pulses emitted by a radio-frequency antenna of a magnetic resonance system, comprising the steps of: initially exciting a test volume slice by emitting radio-frequency pulses with a defined pulse amplitude from said radio-frequency antenna, and determining one-dimensional, spatially-resolved characteristic values along an extent direction of the test volume slice, said one-dimensional, spatially resolved characteristic values respectively representing a local field strength of the radiated radio-frequency field in strips of the test volume slice proceeding perpendicularly to said extent direction; forming an arithmethic mean value of said characteristic values at least over one predetermined segment along said extent direction; and from said arithmethic mean value, determining and setting a pulse amplitude of radio-frequency pulses to be emitted in a diagnostic magnetic resonance measurement.
