Abstract:
The present invention is a method to register 3D image data with fluoroscopic images of the chest of a patient. The ribs and spine, which are visible in the fluoroscopic images, are analyzed and a rib signature or cost map is generated. The rib signature or cost map is matched to corresponding structures of the 3D image data of the patient. Registration is evaluated by computing a difference between the fluoroscopic image and a virtual fluoroscopic projected image of the 3D data. Related systems are also described.

Claim (Index 17):
A fluoroscopy assistance system to assist with registering 3D data with fluoroscopic images of a thorax of a patient comprising a computer processor programmed to:\n receive a fluoroscopic image data set of the thorax including an anatomical structure which is visible under fluoroscopy; receive a 3D data set of the thorax including the anatomical structure; computing a candidate signature representing the anatomical structure based on the fluoroscopic image data and a virtual signature based on the 3D data set; register the 3D data set with the fluoroscopic image data set based on the at least one of the candidate signature and the virtual signature; and computing a difference between the candidate signature of the anatomical structure and the virtual signature of the anatomical structure from the 3D data set.
