Disclosed is an apparatus for mounting an anatomical positioner on a patient care platform in the form of a table mount for use with a Citow Cervical Visualizer type shoulder press to allow the correct positioning of a patient without the assistance of an operator when undergoing x-ray or radiation therapy. The anatomical positioner includes a clamping mechanism for allowing an operator to quickly and securely join the apparatus to the patient care platform. Guide rails are joined to the clamping mechanism. The guide rails extend away from the patient care platform. Slides slidably join to the guide rails to allow the operator to position the anatomical positioner to impart a force on a patient on the patient care platform. The slides include brakes for at least stopping movement in a direction away from the patient care platform, and brake releases for releasing the brakes. Supports join to the slides for supporting the anatomical positioner. The supports have restraints for allowing the operator to quickly secure and adjust the anatomical positioner, whereby the anatomical positioner is positioned by the operator to impart the force on the patient and locked in place.
