Abstract
A marking and tracking apparatus for stereotactic surgery on a body. The apparatus includes a rigid scanning frame. The scanning frame includes a set of scanning markers for making corresponding images in a scanned image of the body, and multiple mounting points, such that when the scanning frame is attached to the body, each of the mounting points mates with a corresponding one of multiples anchors, such as threaded inserts, embedded in the body. The apparatus can also include a rigid tracking frame. The tracking frame includes a set of tracking markers for tracking a position of the frame using a remote sensing device, and multiple mounting points, such that when the tracking frame is attached to the body, each of the mounting points mates with a corresponding one of the anchors embedded in the body.
