Claim 18:
19. The C-arm registration method of claim 16, wherein analyzing, via the C-arm registration controller, the ripple pattern within the X-ray image includes:
computing, via the C-arm registration controller, at least one frequency parameter from the identification of the ripple pattern within the X-ray image;
applying, via the C-arm registration controller, a Fast Fourier Transform to the computation of the at least one frequency parameter from the identification of the ripple pattern within the X-ray image; and
deriving, via the C-arm registration controller, the at least one transformation parameter from an application of the Fast Fourier Transform to the computation of the at least one frequency parameter from the identification of the ripple pattern within the X-ray image.
