Mirroring in image guided surgery

An imaging system, comprising:

• a head-mounted display configured to be worn by an operator while performing a procedure on a human subject;
• a camera attached to the head-mounted display and configured to acquire images that include a patient marker attached to the human subject and at least a portion of a tool being used by the operator in performing the procedure on the human subject, wherein the patient marker defines a plane of asymmetry;
• a memory configured to store a graphical representation of the tool and an image of anatomy of the human subject;
• and
• one or more processors configured to:
• determine a first plane and a second plane that each have a preset acute angle to the plane of asymmetry, with the first plane defining a first acute-angled wedge region on a first side of the plane of asymmetry and the second plane defining a second acute-angled wedge region on a second side of the plane of asymmetry;
• analyze one or more images of the acquired images so as to identify that the camera is located on the first side of the plane of asymmetry;
• render to the head-mounted display the image of the anatomy of the human subject with the graphical representation of the tool superimposed thereon, from a point of view of the first side of the plane of asymmetry;
• analyze one or more additional images of the acquired images so as to identify that the camera has moved from the first side of the plane of asymmetry to the second side of the plane of asymmetry, and so as to identify whether the camera has crossed the second acute-angled wedge region;
• and
• responsive to identifying whether the camera has crossed the second acute-angled wedge region:
• render to the head-mounted display the image of the anatomy of the human subject with the graphical representation of the tool superimposed thereon, from a point of view of the second side of the plane of asymmetry, if the camera has crossed the second acute-angled wedge region, and
• render to the head-mounted display the image of the anatomy of the human subject with the graphical representation of the tool superimposed thereon, from a point of view of the first side of the plane of asymmetry, if the camera has not crossed the second acute-angled wedge region.
