Abstract

IntroductionComputerised tomography (CT) and magnetic resonance imaging (MRI) are used throughout medicine, with images typically viewed in sagittal, coronal and axial planes as two‐dimensional (2D), greyscale representations of the subject matter. New breakthroughs in virtual reality (VR) technology offer the ability to interactively view scans as three‐dimensional (3D) images, with the potential to enhance interpretation for clinical planning [1]. We are interested in the feasibility of using VR software to support decision‐making in patients with potentially difficult airways.Process and applicationThe CT digital imaging and communications in medicine (DICOM) file from an anonymised patient with a known head and neck pathology (supra‐glottic/glottic lesion) was entered into 3D modelling software (D2P; 3D Systems, Inc., South Carolina, USA). The subsequent 3D image was then viewed using a VR system (VIVE Cosmos Elite; HTC Corporation, Taoyuan City, Taiwan) which included a VR headset and two hand controllers linked to a number of room sensors.
