Abstract
Various embodiments of the present disclosure include a C-arm registration system employing a controller () for registering a C-arm () to a X-ray ring marker (). The X-ray ring marker () includes a coaxial construction of a chirp ring () and a centric ring () on an annular base (). In operation, the controller () acquires a baseline X-ray image illustrative of the X-ray ring marker () within a baseline X-ray projection by the C-arm () at a baseline imaging pose, derives baseline position parameters of the X-ray ring marker () within the baseline X-ray projection as a function of an illustration of the centric ring () within the baseline X-ray image, and derives a baseline twist parameter of the X-ray ring marker () within the baseline X-ray projection as a function of the baseline position parameters and of an illustration of the chirp ring () within the baseline X-ray image.
