A tilt and roll device has been developed to add two additional degrees of freedom to an existing treatment table. This device allows computer‐controlled rotational motion about the inferior–superior and left–right patient axes. The tilt and roll device comprises three supports between the tabletop and base. An automotive type universal joint welded to the end of a steel pipe supports the center of the table. Two computer‐controlled linear electric actuators utilizing high accuracy stepping motors support the foot of table and control the tilt and roll of the tabletop. The current system meets or exceeds all pre‐design specifications for precision, weight capacity, rigidity, and range of motion.
