mrinufft.trajectories.utils.unnormalize_trajectory(trajectory: ndarray[tuple[int, ...], dtype[_ScalarType_co]], acq: Acquisition | None = None) → ndarray[tuple[int, ...], dtype[_ScalarType_co]][source]#

Un-normalize a NUFFT-normalized trajectory.

Parameters:

  • trajectory (NDArray) – Normalized trajectory consisting of k-space coordinates in 2D or 3D.

  • acq (Acquisition, optional) – Acquisition configuration to use. If None, the default acquisition is used.

Returns:

trajectory – Un-normalized trajectory corresponding to trajectory input.

Return type:

NDArray
