20230046025 · 2023-02-16 · ·

In a gantry for a computed tomography device, a rotary frame is arranged on the tilt frame so that the rotary frame rotates relative to the tilt frame about an axis of rotation. The tilt frame is arranged on the support frame so that the tilt frame tilts about a tilt axis relative to the support frame, such that a tilt angle of the tilt frame relative to the support frame is changeable by a tilting movement of the tilt frame relative to the support frame about the tilt axis. The proximity switch has a proximity sensor and a reference mark, which interacts with the proximity sensor. The proximity switch is also coupled to the support frame and to the tilt frame such that the proximity switch is configured to react to an approach of the tilt angle to a reference angle.
