PulmoVR places a digital twin of the patient in front of the surgeon. The digital twin is combined of patient CT-scans and segmentations which visualizes anatomic structures as airways, arteries, veins and segments. The user has complete control over position of the digital twin meaning, it can be placed in any position. Likewise, the user has full control over the CT-scan and segmentesd structures so any can be adjusted in opacity, brightness, color or values. The structures can be selected individually from each other. For example, within the presets function with a single click, the surgeon can decide to only show the airways and segments or veins and airways or decide own desired presets. User have even more visual freedom than in the operating room.
