- mrinufft.trajectories.trajectory3D.initialize_3D_golden_means_radial(Nc, Ns, in_out=False)[source]#
Initialize 3D radial trajectories with golden means-based structure.
The radial shots are oriented using multidimensional golden means, which are derived from modified Fibonacci sequences by an eigenvalue approach, to provide a temporally stable acquisition with widely spread shots at all time.
This function reproduces the proposition from [Cha+09], with in addition the option to switch between center-out and in-out radial shots.
- Parameters:
- Returns:
3D golden means radial trajectory
- Return type:
array_like
