Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The project is to conduct a prospective study to compare patient characteristics (age, height, weight, gender, smoking, sign of chronic obstructive pulmonary disease (if available), and dimensions of the trachea and of the main bronchi from CT scans with 3D reconstruction.
