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

Integrate slew rates over time to provide gradients.

Parameters:

  • slewrates (NDArray) – Slew rates over 2 or 3 directions.

  • initial_gradients (NDArray, optional) – Gradients at the beginning of the readout window. The default is None.

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

Returns:

gradients – Gradients corresponding to slewrates.

Return type:

NDArray
