1. A method for registering a virtual representation of a patient anatomy with a coordinate system of a physical patient anatomy, comprising:
displaying first overlap data in a head-mounted device, wherein the first overlap data describe from a first perspective onto the physical patient anatomy a first visual overlap between the virtual representation of the patient anatomy and the physical patient anatomy,
identifying at least a first area in the first visual overlap and/or at least a first anatomical feature of the patient anatomy in the first visual overlap having at least a minimum degree of alignment between the virtual representation and the physical patient anatomy,
displaying second overlap data in the head-mounted device, wherein the second overlap data describe from a second perspective onto the physical patient anatomy a second visual overlap between the virtual representation of the patient anatomy and the physical patient anatomy, and
taking into account, during the displaying of the second overlap data, the alignment of the identified first area and/or anatomical feature of the patient anatomy that was identified in the first visual overlap as having at least a minimum degree of alignment between the virtual representation and the physical patient anatomy.
