Claim 6:
7. An apparatus for radiographic imaging of a body cavity, comprising:
a guidewire configured for being inserted in the body cavity, the guidewire comprising a position sensor, operating in a tracking system, at a distal end of the guidewire;, a display screen;
a processor coupled to the position sensor and to the display screen, configured to:
store and display a CT image of the body cavity;
register the tracking system with the CT image;
track a position of the distal end;, display on the display screen the tracked position of the distal end superimposed on the CT image;
assign voxels within a predefined imaging volume relative to the distal end and having a radiodensity less than a predetermined threshold to have a uniform radiodensity of a predefined default value, wherein the predetermined threshold comprises a radiodensity of mucus;
incorporate the voxels with the assigned predefined default value into the CT image so as to form an updated CT image; and
display the updated CT image on the display screen.
