Abstract
A system for determining a position or an orientation of a probe across a drape may include a fiducial assembly that may be coupled to the probe though a drape. The fiducial assembly may include a base, a coupling attached to the base which may be configured to couple the fiducial assembly to the probe across the drape, and one or more fiducials attached to the base. Coupling the fiducials to the probe across the drape can allow sterile fiducials to be coupled to a non-sterile probe to determine the position and orientation of the probe based on images from the of the fiducials on a sterile side of the drape. In some embodiments, the fiducial is aligned with respect to an elongate axis of the probe with a predetermined offset and orientation with respect to the elongate axis of the probe.
