Inspiration

Expiration

Please note the narrowing of the right and left main bronchi are due to the patient moving in the scanner, and are not a true stenosis.

Original CT scan

The original inspiratory trans axial section Aquilion data set has 429 slices. The slices are spaced 1.0 mm with 0.5mm overlap. Scanned on Aug. 16, 2002.
The original expiratory trans axial section Aquilion data set has 432 slices. The slices are spaced 1.0 mm with 0.5mm overlap. Scanned on Aug. 16, 2002.
