Abstract: Among other things, a guide unit and a radiation system including a guide unit are provided. The guide unit limits axial movement of a rotatable structure supporting a radiation source and a detector array of the radiation system. Embodiments of the guide unit include a frame member configured to be supported by a stationary unit that forms a portion of the radiation system. A guide wheel coupled to the frame member is configured to roll along a periphery of the rotatable structure of the radiation system as the rotatable structure supporting the radiation source and the detector array is rotated about an axis of rotation during operation of the radiation system. A wheel adjustment system coupled to the frame member linearly translates the guide wheel toward the periphery of the rotatable structure supported by the stationary unit of the radiation system.
