  • Direct skew control and interlock of gantry
    Patent number: 6246203
    Abstract: Systems and methods are described for direct skew control and interlock of a gantry. An apparatus includes a gantry that includes a first member defining a gantry primary axis Z, a cross member defining a secondary axis X that is coupled to the first member via a trunnion, and a second member defining a gantry primary axis Z′ coupled to the cross member via an elastic hinge. A method for controlling skew on a cross member moved by a first and second driver includes moving the first and second drivers to a first position, measuring a resulting skew value, and correcting the skew on the cross member by moving the first driver and/or the second driver.
