Assignee: BRAINLAB AG
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 13:
14. A medical system, comprising:
at least one computer having at least one processor and memory, the memory having instructions stored thereon to cause the at least one processor to:
position data is acquired, describing a spatial position of an object observed through an AR-device relative to the spatial position of the AR-device and/or the spatial position of the eyes of a user of the AR-device;
viewing-characteristics data is determined based on the position data, describing at least one characteristic of an user's view at the object; and
visualization data is determined based on the viewing-characteristics data, describing the AR-overlay which is projected into a field of view provided by the AR-device, wherein the content of the AR-overlay which is positionally registered with the field-of-view provided by the AR-device is changed in correspondence with a change of at least one characteristic of the user's view;, wherein
a visualization of larger structures changes to a visualization of smaller structures, specifically in accordance with a decreasing distance between the AR-device and the object, and vice versa;
different components or parts of a patient's anatomy are displayed, specifically depending on a spatial direction of a visual axis;
information on the patient's anatomy is displayed, specifically depending on a tilt angle of the AR-device; and/or
acquired 2D and/or 3D images, measurements, planned craniotomies, trajectories or orientations of instruments or implants are displayed, specifically depending on their alignment with respect to the spatial direction of a visual axis;
at least one electronic data storage device storing at least a patient data; and
an AR-device for providing an AR-overlay,
wherein the at least one computer 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 vizualization data, and
the AR-device for providing an AR-overlay on the basis of the visualization data.
