Patient History for Tracheal Stenosis

MPEG Movies of the Tracheal Stenosis

The original Imatron CT scan.

The original trans axial section -- slice Cine CT data set of a patient. The volumetric data acquisition of 3 mm thickness with a 1.5 mm overlap of the slices which includes the larynx, the trachea, and the lungs.

Surface Display of airway.

This movie is of the airway from the larynx to just above the main bronchus. This movie rotates about the y axis in ten degree increments.
