add_phase_to_kspace_with_shifts#

mrinufft.io.add_phase_to_kspace_with_shifts(kspace_data: NDArray, kspace_loc: NDArray, normalized_shifts: NDArray)[source]#

Add phase shifts to k-space data.

Parameters:

  • kspace_data (np.ndarray) – The k-space data.

  • kspace_loc (np.ndarray) – The k-space locations.

  • normalized_shifts (tuple) – The normalized shifts to apply to each dimension of k-space. They are expressed as a number of pixels to shifts.

Returns:

The k-space data with phase shifts applied.

Return type:

ndarray

Raises:

ValueError – If the dimension of normalized_shifts does not match the number of dimensions in kspace_loc.
