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.

C-arm pose estimation using intensity-based registration of imaging modalities

Provided are methods and systems for registering image data from two imaging modalities, to produce an image having features from both imaging technologies. In particular, the methods and systems relate to intensity-based registration of the image data. The imaging modalities may be, for example, ultrasound and x-ray, magnetic resonance imaging, or a pre-operative plan.
