1. A device for stabilizing a head of a patient during a medical procedure, wherein the device comprises:
(a) a skull clamp having a pair of arms, each with an upright portion, a lateral portion, and an end that is configured to receive a stabilization assembly, wherein the lateral portions are translatable relative to one another to adjust a spacing of the respective upright portions to adjust a width of the skull clamp, the skull clamp further comprising at least one first integrated marker positioned along the upright portion and/or the lateral portion of a select one or more of the arms of the pair of arms, wherein the at least one first integrated marker is detectable by an MRI scanner, wherein the at least one first integrated marker is configured to provide at least one first reference point relative to an operation site in one or more images for use in a navigation guided procedure; and
(b) a primary reference marker detectable by a navigation system, wherein the primary reference marker is selectively connectable with the skull clamp in a single orientation fixed relative to the skull clamp and the at least one first integrated marker, and wherein the primary reference marker is configured to provide a reference origin for defining a position of the at least one first reference point relative to the operation site.
