Claim 15:
16. A C-arm registration method executable by a C-arm registration controller for registering a C-arm to an X-ray ripple marker including ripple pattern radially extending from a fixed point of the X-ray ripple marker, the C-arm registration method comprising:
identifying, via the C-arm registration controller, 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 the 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,

analyzing, via the C-arm registration controller, 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
registering, via the C-arm registration controller, the C-arm to the X-ray ripple marker based on the at least one transformation parameter.
