Method and magnetic resonance apparatus to acquire a magnetic resonance data set by radial scanning

A magnetic resonance apparatus comprising:

• a magnetic resonance data acquisition unit;
• an electronic memory comprising a plurality of data entry points therein organized as k-space;
• a control unit configured to operate the magnetic resonance data acquisition unit to acquire raw magnetic resonance data from a subject situated in the magnetic resonance data acquisition unit;
• a processor supplied with said raw magnetic resonance data, said processor being configured to enter said raw magnetic resonance data into said electronic memory by radially entering said raw magnetic resonance data along respective data points in a fixed number of spokes in k-space, with each of said spokes being described by a first angle in k-space, and wherein said acquisition area in said subject deviates from a circular shape and has a shape that is described collectively by said respective first angles;
• said processor being configured to enter said raw magnetic resonance data into respective spokes according to an acquisition order of respective positions of said spokes, said acquisition order defining said respective positions by comparison of said first angle with a data set of a fixed number of second angles for successive acquisition positions that differ by a golden angle, so as to cause, for each first angle of each acquisition position, respective spatially adjacent first angles thereto to have the same acquisition positions as the respective second angles that are spatially adjacent to the second angle of the respective acquisition position;
• and
• said processor being configured to make the raw magnetic resonance data entered into k-space available from said electronic memory in an electronic form for reconstructing a magnetic resonance image of said acquisition area therefrom.
