In a method for the determination of sensitivity profiles of local coils in the acquisition of magnetic resonance data, a first measurement data set of an examination area is acquired with a first acquisition coil, a second measurement data set of the examination area is acquired with a local coil, and a sensitivity profile of the local coil that is used is determined on the basis of the first measurement data set and the measurement data set. The first measurement data set and the second measurement data set are acquired using a pulse sequence with ultrashort echo times. In the determination of the sensitivity profile, errors due to dephasings are avoided as best as possible by the acquisition of the measurement data sets with a pulse sequence with ultrashort echo times (i.e. in particular echo times TE shorter than 0.5 ms); in particular, the dephasings are smaller given these echo times than in the case of gradient echo (GRE)-based pulse sequences.
A method to determine a sensitivity profile of a local coil in a magnetic resonance apparatus, comprising:
A magnetic resonance apparatus comprising:
A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a computerized processor of a magnetic resonance apparatus, comprising an RF acquisition coil and a local coil, and said programming instructions causing said computerized processor to:
