Make a radial transform ("cake") BEFORE you apply any filters.

Wouldn't go so far as to call it a body. There's not much to discuss? For
a texture free, non-grainy powder the signal should not vary around the
Debye Scherrer cone. So you can filter in that direction, removing for
example, a shadow from the beamstop arm.
