Removable frames for stereotactic localization
DCFirst Claim
1. A rigid scanning frame for stereotactic surgery on a body on which a plurality of anchors are affixed in a fixed geometric relationship comprising:
- a plurality of scanning markers affixed to the scanning frame at a plurality of locations on said frame for making corresponding images in a scanned image of the body; and
a plurality of positioning elements arranged on the scanning frame in a fixed geometric relationship such that each of the plurality of positioning elements is attachable to a different one of the plurality of anchors and the locations of the scanning markers are predetermined in relation to the anchors when the scanning frame is attached to the anchors on the body.

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.
