Radiation-proof CT image scanning device

The utility model belongs to the field of medical instruments. The utility model relates to a scanner, in particular to a radiation-proof CT image scanner. A built-in control machine of an existing device is arranged inside; once maintenance or repair is needed, the motor is started; maintenance personnel need to handle in the device. Narrow internal space of device, inconvenience for maintenancepersonnel to operate, the working efficiency is reduced; proposed now is the following scheme, the CT scanning device comprises a CT scanning device shell, a maintenance hole and a fixing hole are formed in the inner wall of one side of the CT scanning device shell. The fixing hole is positioned above the maintenance hole; according to the utility model, the structure is simple, when the built-incontrol machine in the CT scanning device shell needs to be maintained or repaired, the built-in control machine is started; when the pull block is pulled to drive the maintenance door to rotate, thebuilt-in control machine po
