Nasal cavity model 2 (NC02)
CT scans of a healthy nose from a 51-year-old Asian male were obtained with the subject's approval
and consent for participation in the study. The scans were performed on a Philips whole-body scanner
at No. 3 Hospital, Shanghai: slice thickness 0.625 mm, pixel spacing 0.976 × 0.976 mm, a 300 × 500 mm
field of view, 30 kV peak and 200 mA.
The outline of the model was segmented from the scans and a computational mesh applied. Two models
were reconstructed from the same scans: NC02 (nasal cavity without paranasal sinuses) and NC02-S (with
the sinuses). The length from the anterior-most region to the posterior nasopharynx is about 9 cm, and
the height from the main nasal passage floor to the superior tip of the frontal sinus about 7 cm.
