This invention provides a method for estimating C-arm fluoroscope pose. The method involves introducing a coordinate system into a C-arm image, and applying intensity-based 2D/3D registration without segmentation to the coordinate system C-arm image and an image or known model of the coordinate system, wherein the intensity-based 2D/3D registration yields the C-arm pose. The coordinate system may be provided by introducing one or more markers or a fiducial into an image.
