Radiation: Cone Beam Computed Tomography
- Changes in upper airway geometry [ Time Frame: At day 1 ]The primary objective of this study is to compare the volume and resistance of the upper airway in supine versus upright position using High Resolution Computed Tomography (HRCT) and Cone Beam Computed Tomography (CBCT) images.
- Body mass index (BMI) [ Time Frame: At screening and also at day 1 (if interval screening - day 1 > 14 days) ]In addition the effect of elevated BMI on the changes in upper airway morphology will be assessed.
