Abstract
In a method for adjustment of a B1 field in a magnetic resonance apparatus, the position of the measurement subject relative to a coordinate system is determined from a plurality of measurement subjects with a morphological magnetic resonance measurement. Respective tissue types of the measurement subject are determined using three-dimensional measurement subject data and a segmentation of the measurement subject into regions is effected using the tissue types having known dielectric properties. The segmentation and the association for all positions of the measurement subject are recorded for all subjects in respective entries of a database. A radio-frequency simulation for transmission coils is implemented with the entries of the database wherein electrical field distributions and/or B1 field distributions related to spatial elements are determined and are entered as results into the database, that is then used further magnetic resonance examinations.
