snake.core.sampling.factories.get_kspace_slice_loc(dim_size, center_prop, accel=4, pdf=VDSpdf.GAUSSIAN, rng=None, order=VDSorder.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”.

  • rng (random state)

  • order (VDSorder)

Returns:

np.ndarray

Return type:

array of size dim_size/accel.
