bartorch.tools.raga()#

Generate file with RAGA indices for given approximated tiny golden ratio angle/raga increment and full frame spokes.

Runs bart raga.

Parameters:

  • spokes (int) – Positional int.

  • tiny_angle (int | None, default=None) – tiny (small) golden ratio angle (-s)

  • raga_inc (int | None, default=None) – Increment of RAGA Sampling (-r)

  • echoes (int | None, default=None) – Number of (non-aligned) echoes (-e)

  • slices (int | None, default=None) – Number of (non-aligned) slices (-m)

  • partitions (int | None, default=None) – Number of (non-aligned) partitions (-z)

  • inversions (int | None, default=None) – Number of (non-aligned) inversions (-i)

  • shifts (int | None, default=None) – Number of (non-aligned) shifts (-c)

  • no_double_base (bool, default=False) – Define GA over Pi base instead of 2Pi. (--no-double-base)

  • search_tiny (bool, default=False) – Search for tiny golden-angle index with given number of spokes. (--search-tiny)

  • **extra (Any) – Further BART flags, passed through by name.

Returns:
