Abstract

Method to acquire a magnetic resonance data set of an acquisition area (5) in a subject (O) via radial scanning along a fixed number of spokes (6) respectively described by a first angle in k-space, wherein the acquisition area (5) deviates in positional space from a circular shape in a shape that can be described by the set of first angles; wherein the acquisition of the spokes (6) takes place according to an acquisition order; wherein an acquisition position of the acquisition order is associated with each first angle under consideration of a comparison data set of the fixed number of second angles (in which second angles of successive acquisition positions differ by a golden angle) such that, for a first angle of each acquisition position, the spatially adjacent first angles have the same acquisition positions as the second angles spatially adjacent to a second angle of the acquisition position.
