bartorch.tools.sake()#

Use SAKE algorithm to recover a full k-space from undersampled data using low-rank matrix completion.

Runs bart sake.

Parameters:

  • kspace (torch.Tensor) – Input array.

  • i (int | None, default=None) – number of iterations (-i)

  • s (float | None, default=None) – rel. size of the signal subspace (-s)

  • o (float | None, default=None) – () (-o)

  • **extra (Any) – Further BART flags, passed through by name.

Returns:

output

Return type:

torch.Tensor
