The CT scanning frame is connected with a peripheral structural frame through a fixed support to fix the parking position of the whole CT scanning machine and the relative structure among all the components. The conventional CT scanning frame is fixed by wrapping the peripheral structure of the CT scanning machine, and a larger-sized CT fixing support is required for fixing the position. Furthermore, the conventional CT scanner has a large overall size and occupies a relatively large area.

The CT scanner has high requirements on a field in the use process, the flatness of the ground of a conventional house cannot meet the requirements of safe use of the CT scanner, and the flatness of the ground is generally processed corresponding to the arrangement position of the CT scanner. In particular, for the processing of the flatness of the ground on which the CT scanner is placed, the conventional CT scanner or CT scanner occupies a large area, so that the area required for ground processing is relatively large, and the corresponding working hours and cost are also large. With the popularity of CT scanning devices, more and more hospitals begin to use such devices.

In order to reduce the corresponding construction cost and the requirement for the site, the time and the site for equipment configuration are saved. A need exists for a reduction in volume for conventional CT scanners and/or their structural components.
