FIG 3.

Virtual space sharing and mixed reality. The images in this figure are screenshots from the proctor's computer livestreamed from the operator in the angiography suite. The upper panel shows a view through the operator's headset as displayed on the proctor's computer. It shows the operator logging into the Spatial app (A1). The proctor has displayed an image regarding aneurysm size and morphology in the operator's visual field at about 10 o'clock (A2) using the Spatial app and the same image with the operator's avatar looking at it in the virtual room created on the app. The middle panel shows a WEB-sizing chart (B1), 3D image of the aneurysm flow model (B2), and an angiography image annotated by the proctor defining the WEB device (B3). The lower panel shows a 3D model of another aneurysm showing that the operator can manipulate and anchor in his FOV as a reference to be used when necessary.
