Abstract
An instrument registers and tracks a portion of a patient's anatomy by an Augmented Reality (AR) device worn by a surgeon during a surgical procedure. The instrument may be attached to the patient's anatomy. The instrument may be a tripod with a platform. A target plate having front and back faces may be securely attached to the platform. A two-dimensional (2D) code detectable by the AR device may be presented on the front and back faces of the target plate. The 2D code may define a coordinate system having a known relationship to a coordinate system for the patient's anatomy, e.g., through a transformation matrix. The AR device may utilize the coordinate system for the detected 2D code and the transformation matrix to present holograms in predetermined positions relative to the patient's anatomy.
