Abstract
A motion system for use in a panoramic dental radiation imaging system, including apparatus for rotating an overhead arm with respect to a support column, apparatus for rotating a C-arm with respect to the overhead arm, and apparatus for moving the C-arm axially with respect to the overhead arm. The overhead arm is rotatably mounted to the support column at a rotation point. The apparatus for rotating the overhead arm is a linear actuator, one end of which is connected to the support column at a first point spaced apart from the rotation point, while the other end is connected to the overhead arm at a second point spaced apart from the rotation point and from the first point. The C-arm rotating apparatus includes a C-arm rotation motor driving a wheel, which is engaged with the C-arm in such a way that the rotation of the wheel causes rotation of the C-arm.
