Abstract

This document discusses, among other things, fiducial marker devices, tools, and methods. One example illustrates a combined computed tomography (CT) imageable fiducial locator head, an integral bone screw, and an integral divot for receiving a positioning wand of an image-guided surgical (IGS) workstation. A further example includes a fluid/gel-absorbing coating or cover into which a magnetic resonance (MR) imageable fluid is introduced, thereby permitting both CT and MR imaging. Protective caps and collars may be used to protect the fiducial marker from mechanical impact and/or to guide the fiducial marker during affixation. A bull's-eye or other template is used to select a center of a substantially spherical fiducial marker head on an image, such as for use during patient registration.
