Claim 10:
11. A C-arm registration controller, comprising:
a non-transitory machine-readable storage medium encoded with instructions for execution by at least one processor of a registration of a C-arm to an X-ray ripple marker including a ripple pattern radially extending from a fixed point of the X-ray ripple marker, the non-transitory machine-readable storage medium comprising instructions to:
identify the ripple pattern within an X-ray image generated from an X-ray projection by the C-arm and illustrative of at least a portion of the ripple pattern,
wherein an identification of the ripple pattern within the X-ray image is characteristic of a pose of the X-ray projection by the C-arm relative to the X-ray rippler marker;

analyze the ripple pattern within the X-ray image to derive at least one transformation parameter definitive of the pose of the X-ray projection by the C-arm relative to the X-ray rippler marker; and
register the C-arm to the X-ray ripple marker based on the at least one transformation parameter.
