bartorch.tools.ccapply()#

Apply coil compression forward/inverse operation.

Runs bart ccapply.

Parameters:

  • kspace (torch.Tensor) – Input array.

  • cc_matrix (torch.Tensor) – Input array.

  • p (int | None, default=None) – perform compression to N virtual channels (-p)

  • u (bool, default=False) – apply inverse operation (-u)

  • t (bool, default=False) – don’t apply FFT in readout (-t)

  • S (bool, default=False) – type: SVD (-S)

  • G (bool, default=False) – type: Geometric (-G)

  • E (bool, default=False) – type: ESPIRiT (-E)

  • A (int | None, default=None) – Align the coil sensitivities along this axis. (-A)

  • W (torch.Tensor | None, default=None) – pre-whiten k-space before cc (-W)

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

Returns:

proj_kspace

Return type:

torch.Tensor
