ABSTRACT:
In a measurement sequence and apparatus for three-dimensional magnetic resonance imaging, in which an acquisition of measurement data ensues by scanning multiple lines in k-space; and the number of k-space lines is apportioned among a number of partial acquisitions so that scanning of associated k-space lines occurs in each partial acquisition, the k-space lines are associated with the partial acquisitions such that the association corresponds to the following association rule: (a) evaluation of each k-space line with a distance measure that characterizes the distance of the respective k-space line relative to the k-space center, (b) arrangement of the k-space lines to be scanned in an order dependent on the distance measure, (c) grouping of the k-space lines arranged in order into a number of groups with a number of successive k-space lines being combined into a group, and (d) association of the k-space lines with the partial acquisitions by, for each group, the k-space lines combined into this group are apportioned to different partial acquisitions.
