摘要： In a method and apparatus for magnetic resonance imaging on the basis of a gradient echo sequence by excitation of nuclear spins and measurement of radio-frequency signals indicating the excited nuclear spins, a) the pulse frequency of the person to be examined is determined, b) the magnetization of the spins is prepared by means of an RF pulse block, c) a number of steps of the spin excitation as well as measurement of an RF response signal are implemented, with the measurement data along a trajectory established by projection gradients being acquired along a first slice established by a slice-selection gradient, d) items b) through c) are repeated multiple times for the first slice, with each repetition of the steps b) through c) ensuing within a time interval that is fixed in duration, and the interval is temporally displaced relative to the determined pulse frequency for at least one portion of the repetitions, and e) items b) through d) are repeated for various slices.

摘要： In a method for imaging a periodically-moving subject region of a subject, an overview image data set is initially obtained that maps a movement of the subject region, at least two positions that the subject region assumes at corresponding points in time are marked in the overview image, further positions of the subject region at further points in time are interpolated from the marked positions and further points in time, and a subsequent diagnostic imaging of the moving subject region is implemented using the marked and interpolated positions.

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.
