voronoi#

mrinufft.density.voronoi(traj, *args, **kwargs)[source]#

Estimate density compensation weight using voronoi parcellation.

In case of multiple point in the center of kspace, the weight is split evenly.

Parameters:

  • traj (array_like) – array of shape (M, 2) or (M, 3) containing the coordinates of the points.

  • *args – Dummy arguments to be compatible with other methods.

  • **kwargs – Dummy arguments to be compatible with other methods.
