get_random_loc_1d#

mrinufft.trajectories.tools.get_random_loc_1d(dim_size, center_prop, accel=4, pdf='uniform', rng=None, order='center-out')[source]#

Get slice index at a random position.

Parameters:

  • dim_size (int) – Dimension size

  • center_prop (float or int) – Proportion of center of kspace to continuouly sample

  • accel (float) – Undersampling/Acceleration factor

  • pdf (str, optional) – Probability density function for the remaining samples. “gaussian” (default) or “uniform” or np.array

  • rng (int or np.random.Generator) – random state

  • order (str) – Order of the lines, “center-out” (default), “random” or “top-down”

Returns:

np.ndarray

Return type:

array of size dim_size/accel.
