ABSTRACT:
The invention is an improved head support stand used to smoothly and accuely position a patient's head when imaging the patient's upper spinal area. The improved stand includes a compound turnbuckle mounted between a base of the stand and a head cradle or face plate mounted to the base. The compound turnbuckle includes two rods threadingly engaged to a turnbuckle body so that the rods translate with respect to the body when it rotates. When the compound turnbuckle is in a fully retracted position, the rods are in a telescoped configuration within the turnbuckle body. When the compound turnbuckle is in a fully extended position, the rods are axially remote from each other and project substantially all the way out of the turnbuckle body.
