摘要:
In a method and apparatus to acquire a measurement data set of a breathing examination subject by magnetic resonance, the measurement data set is acquired in multiple shots each composed of a number of k-space trajectories (views), with the number Nv of views per shot being selected. The number of shots is determined in order to completely fill k-space to be scanned. The views of the shots are associated with sectors in k-space, such that approximately the same number of views are arranged in each sector, and such that all views in a sector have a similar distance from the k-space center. A respective view of each sector is associated with a respective one of the shots, corresponding to the orientation of the respective shot in the kz-ky plane. The views of each shot are scanned such that views that are associated with the same sector and different shots respectively assume the same time position within the shot.
