Figure 2. VR Basic Operations on 3-D CT Lung Model.

Figure 2.

We demonstrate the maneuverability within VR to explore the 3-D model moving from an initially centralized view (A) to a 90° rotated view (B) and a 270° perspective (C), the scale is noted at 100mm (A). The 100% opacity model (A-C) is returned to a centralized view wherein we demonstrate the adjustable opacity functionality (D, E). We adjust the opacity to 50% (D) visibly displaying the inner distinction between lobes within the lung, then further adjust the opacity to 0% (E) to display the visibility of the pulmonary vessels for analysis. We represent VR immersion by going into the lung and viewing the 3-D pulmonary vessels (F). Inside VR to enhance model analysis, it is demonstrated that a measurement functionality (G) is present, for quantitative information, displaying “Distance: 23.27mm” and a labeling functionality (H), for qualitative description, details a specific model section as the “Right Pulmonary Vessels”. Scale bar: 100 mm.
