Abstract
A patient marker couples to an anchoring device via a base having a base axis, base connections and a first indicator. The marker includes: an adapter having a first surface with connections configured to mate with the base connections, and a second surface with connections congruent with the base connections, and at least one second indicator. The marker includes an alignment target, having a target region with an alignment pattern, and a socket connected to the target region with socket connections congruent with the first surface connections. In a first configuration the socket couples to the base by mating the first surface connections with the base connections and mating the socket connections with the second surface connections. In a second configuration, the socket fits onto the base by mating the socket connections with the base connections. One of the indicators indicates a target orientation angle about the base axis.
