Spine level determination using augmented reality

A non-transitory computer readable medium comprising instructions which, when executed by at least one processor of at least one computer, causes the at least one processor to

• acquire body part model data which describes a digital model which comprises a plurality of vertices having a fixed scaling of positions relative to one another, wherein at least one vertex of the plurality of vertices corresponding to a predetermined element of a patient body part;
• acquire viewing device position data which describes a relative position between a head-mountable augmented reality viewing device and at least one position in a reference system used to generate an augmented reality image with the head-mountable augmented reality viewing device;
• and
• determine augmented reality display data based on the body part model data and the viewing device position data.

A medical system, comprising:

• at least one processor operable to execute stored instructions which, when executed, cause the at least one processor to:
• acquire body part model data which describes a digital model which comprises a plurality of vertices having a fixed scaling of positions relative to one another, wherein at least one vertex of the plurality of vertices corresponding to a predetermined element of a patient body part;
• acquire viewing device position data which describes a relative position between a head-mountable augmented reality viewing device and at least one position in a reference system used to generate an augmented reality image with the head-mountable augmented reality viewing device;
• and
• determine augmented reality display data based on the body part model data and the viewing device position data;
• at least one electronic data storage device storing at least the body part model data;
• a head-mountable augmented reality viewing device;
• and
• a navigation device for detecting the position of the viewing device and for example the patient body part, wherein for example the navigation device is part of the head-mountable augmented reality viewing device, and
• wherein the at least one processor is operably coupled to
• the at least one electronic data storage device for acquiring, from the at least one data storage device, at least the body part model data;
• and
• the navigation device for receiving, from the navigation device, an electronic signal corresponding to the viewing device position data;
• and
• the viewing device for transmitting, to the viewing device, electronic signals corresponding to the augmented reality display data.
