摘要： The embodiments relate to a B1-map establishment system for establishing B1-maps, operating using a method including: establishing a number of relative B1-maps and storing the relative B1-maps for subsequent, in particular repeated use. The B1-maps are used in a method for establishing an actuation sequence including: establishing a quantitative B1-map. establishing normalized B1-maps on the basis of the relative B1-maps and the quantitative B1-map, and establishing an actuation sequence or acquiring magnetic resonance measurement data using the normalized B1-maps. Furthermore, the embodiments relate to an actuation sequence establishment system and a magnetic resonance imaging system including such an actuation sequence establishment system.

摘要： The embodiments relate to a method for the optimization of alignment measurements in which a MR facility is configured to a measurement object. First alignment measurements are carried out while the measurement object is being moved through the MR facility, wherein at least one MR system parameter of the MR facility is configured to the measurement object of the first alignment measurements. A second alignment measurement is also carried out in which the measurement object is stationary in a fixed position in the MR facility, wherein the second alignment measurement includes an iterative alignment method in which the at least one MR system parameter for the recording of MR signals of the measurement object is iteratively configured to the measurement object in the fixed position in the MR facility, wherein for the iterative alignment method the aligned MR system parameter is chosen from the aligned MR system parameters.
