convert_slew_rates_to_gradients#
- mrinufft.trajectories.utils.convert_slew_rates_to_gradients(slewrates, initial_gradients=None, raster_time=0.01)[source]#
Integrate slew rates over time to provide gradients.
- Parameters:
slewrates (np.ndarray) – Slew rates over 2 or 3 directions.
initial_gradients (np.ndarray, optional) – Gradients at the beginning of the readout window. The default is None.
raster_time (float, optional) – Amount of time between the acquisition of two consecutive samples in ms. The default is DEFAULT_RASTER_TIME.
- Returns:
gradients – Gradients corresponding to slewrates.
- Return type:
np.ndarray
