Abstract: Systems and methods are provided for improving registration of AR (augmented reality) units at a surgery scene. Systems comprise augmented reality (AR) unit(s) comprising and/or in communication with head mounted display(s) (HMDs) used by a user, and physical device(s) made of sterilizable biocompatible material and configured as a registration template. The AR unit and/or segmentation software associated therewith may be configured to align a device representation of the physical device onto an imaging model of a patient, and the AR unit and/or the HMD may be configured to register, on the HMD, the device representation with the aligned imaging model onto the physical device, which is positioned with respect to the patient and is viewed through the HMD—to display the imaging model or parts thereof in a corresponding spatial relation to the patient. Registration using the physical device simplifies the coordination among real and virtual devices.
