#$%^&*AU2018200128A120180802.pdf#####ABSTRACT A method for radiographic imaging of a body cavity includes imaging the body cavity using computerized 5 tomography (CT) to form a CT image, registering a tracking system with the CT image, inserting into the body cavity a guidewire, including a position sensor, operating in the tracking system, attached to a distal end of the guidewire, in response to signals from the 10 position sensor acquired by the tracking system, displaying a position of the distal end of the guidewire on the CT image. The method further includes assigning voxels within a predefined imaging volume relative to the distal end and having a radiodensity less than a 15 predetermined threshold to have a uniform radiodensity of a predefined default value, incorporating the voxels with the assigned predefined default value into the CT image so as to form an updated CT image, and displaying the updated CT image. 201/6 co Of LLJ C--) CD -::C C ) LL-1 Of U-i co r-o LL00
