Original CT scan

Inspiratory scan :

This scan starts just under the vocal cords of the neck and continues through the left and right main bronchi. There are 132 slices scanned at 3 mm apart with a 1.5mm overlap.

Expiratory scan:

This scan starts near the mouth and continues to the left and right main bronchi. There are 132 slices scanned at 3 mm apart with a 1.5mm overlap.

Surface render

Inspiratory scan:

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