The utility model discloses a console mode structure, supporting legs 102 are installed on the supporting mechanism body, with 101 ground mechanical connections, provide the stable support that falls to the ground of equipment. The inner frame 4 is fixedly arranged at the top of the supporting mechanism body.

Slewing bearing 103 is a large bearing capable of bearing the combined load. The outer ring of the slewing bearing 103 is mechanically connected to the outer frame 3, and the inner ring of the slewing bearing 103 is mechanically connected to the support mechanism body. The slewing bearing 103 can support and ensure the uniformity and the stationarity of the outer frame 3 when rotating relative to the inner frame.

The motor 104 is installed at the inner ring of the slewing bearing 104, and the motor 104 drives the outer ring of the slewing bearing 103 to rotate around the inner ring when working, namely, the motor drives the outer frame 3 to rotate around the inner frame 4 when working.

The utility model discloses normal during operation, including surveyed object (patient) 100 sits in the frame. The inner frame, the inner ring of the slewing bearing 103, the support foot 102 and the ground 101 are mechanically connected to each other. Thus, during operation of the apparatus, the patient and the internal housing are at rest relative to the ground. When the motor 104 rotates, the outer ring of the slewing bearing 103 is driven to rotate, and the outer frame 3 is further driven to rotate relative to the ground 101. During the rotation of the outer frame 3, the radiation source 1 emits X-rays, and the detector 2 receives the X-rays to generate a CT image. The electrical signals between the outer housing 3 and the inner housing 4 are transmitted through the slip ring 6.
