Abstract: Technology is described for a method of enabling a joining user to share a collaboration group, which includes at least one collaboration user. The collaboration group may jointly view an image data set aligned with a body of a person using AR headsets. The method may include detecting a topology of an operating room using a sensor of the joining user's AR headset. The topology of the operating room recorded by the joining user's AR headset may be compared to an operating room topology previously recorded for the collaboration group to determine whether the joining user and the collaboration group are occupying the same operating room. The joining user may be allowed to join the collaboration group, based in part on the same operating room being detected.

Abstract: Technology is described for aligning 3D image data with an anatomical structure of a person. The method can include displaying a slice of the 3D image data with respect to an axis. The slice may be locked to limit movement of the slice with respect to the axis. Adjustments to the slice with respect the axis may be received until an edge of the anatomical structure in the slice aligns with an edge of the anatomical structure of the person. The adjustments may allow the 3D image data to align with the person.
