Abstract: In a method for implementation of a magnetic resonance examination of a patient with an imaging medical magnetic resonance apparatus with a movable patient bed, for of an examination volume of the patient that is larger than an acquisition volume of the magnetic resonance apparatus, anatomical patient information and second technical information for setting the magnetic resonance apparatus are acquired dependent on the position of the patient bed from magnetic resonance signals acquired in a low-resolution calibration measurement (scan). A first group of measurement protocol parameters is generated from the patient information and a second group of measurement protocol parameters is generated from the technical information, to generate a measurement protocol for a subsequent high-resolution magnetic resonance examination.

Abstract: In a method for magnetic resonance imaging on the basis of a partially-parallel acquisition (PPA) reconstruction method and a magnetic resonance tomography apparatus, data for at least two two-dimensional slices of a patient are acquired (which two-dimensional slices are displaced in the direction of a slice-selection gradient (z-gradients) defining the slice-normal direction) with at least one data acquisition in k-space (which acquisition forms a partial data set) per slice with a number of component coils, with the sum of all partial data sets forming a complete data set in k-space. The coil sensitivities of each component coil are determined on the basis of the complete data set. At least one partial data set of each slice is completed with a PPA reconstruction method on the basis of the determined coil sensitivities. The completed slices in k-space are transformed into whole images in the spatial domain.

Abstract: In a method and for MR apparatus PPA imaging with radial data acquisition in magnetic resonance tomography, k-space is under-scanned by acquiring a number of projections ? with a coil array of M component coils, a shift operator C(±n?k) is determined for a projection ?i on the basis of measured magnetizations along a projection ?i±?0 that encompasses with ?i an angle ?0, with n=1, 2, . . . , M?1, the shift operator C(±n?k) is applied to individual points of projection ?i in order to obtain calculated projection points, the determination and the application of the shift operator C(±n?k) are repeated for all projections ?, and an image is reconstructed in the spatial domain on the basis of the projections, which have been completed purely computationally.

Abstract: In a method and apparatus for magnetic resonance imaging based on a partially parallel acquisition (PPA) reconstruction technique, a number of partial k-space data sets are acquired with a number of component coils, the totality of the partial data sets forming a complete k-space data set, the respective coil sensitivity of each component coil is determined based on at least one part of the complete k-space data set, any partial k-space data set is transformed via a PPA reconstruction technique dependent on the determined coil sensitivities, and the transformed partial data sets are superimposed to obtain a low-artifact image data set.
