1. An imaging system, comprising:
a first head-mounted display;
a second head-mounted display;
a patient marker configured to be attached to a human subject and defining a first plane and a second plane, the patient marker comprising optically reflective elements disposed on opposing sides of the first plane in a non-symmetrical arrangement with respect to the first plane and on opposing sides of the second plane in a non-symmetrical arrangement with respect to the second plane,
wherein the patient marker is configured such that, when attached to the human subject, the first plane will make an angle between +20° and −20° with a sagittal plane of the human subject, and the second plane will make an angle between +20° and −20° with an axial plane of the human subject;
a memory configured to store a graphical representation of a tool used in a procedure performed by a wearer of the first head-mounted display on the human subject, and an image of anatomy of the human subject;
a first camera attached to the first head-mounted display and configured to acquire a first input image of the patient marker and of the tool;
a second camera attached to the second head-mounted display and configured to acquire a second input image of the patient marker and of the tool; and
one or more processors configured to:
analyze the first input image to identify the first plane and the second plane, and to identify at least one of: whether the first camera is located on a first side or second side of the first plane, or whether the first camera is located on a first side or second side of the second plane;
render to the first 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 based on the analysis of the first input image;
analyze the second input image to identify the first plane and the second plane, and to identify at least one of: whether the second camera is located on the first side or second side of the first plane, or whether the second camera is located on the first side or second side of the second plane; and
render to the second 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 based on the analysis of the second input image.
