by Janice Cook-Granroth in consultation with Dr. McLennan

Patient History for Tracheal Stenosis

MPEG Movies of the Tracheal Stenosis

Original CT scan

This scan starts trachea and continues through the left and right main bronchi. There are 112 slices scanned at 3 mm apart with a 1.5mm overlap.

Segmented scan:

The trachea, and the bronchi are segmented out of the scan.
