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

Claim 16:
17. A medical system, comprising:
a) at least one computer configured to:
acquire image data which describes a three-dimensional virtual representation of a patient's body part;
acquire position data which describes a spatial position of a user's visual axis within a virtual-world co-ordinate system;
determine visualization data based on the image data and the position data, which describes an image of a virtual representation of the patient's body part as seen along the user's visual axis within the virtual-world co-ordinate system; and
determine virtual-world trajectory data based on the position data, which describes the spatial position of a virtual trajectory with respect to the virtual representation of the patient's body part within the virtual-world co-ordinate system, wherein the spatial position of the virtual trajectory within the virtual-world co-ordinate system is defined to coincide with and to move with the spatial position of the user's visual axis as the user's visual axis is moved within the virtual-world co-ordinate system until the spatial position of the virtual trajectory within the virtual-world co-ordinate system is fixed to a specific spatial position with respect to the virtual representation of the patient's body part via a user input;

b) at least one electronic data storage device storing at least one of the trajectory data and image data; and
c) a display device displaying at least the visualization data to a user, 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 electronic data storage device, at least one of the trajectory data and the image data, and
the display device for issuing a control signal to the display device for controlling the operation of the display device on the basis of at least one of the trajectory data and the image data.
