• the first rotating accessory is so arranged on the rack through a slewing bearing in a rotatable manner;
• the cage-type rotating member and the rack form a ring structure whose center serves as a scanning hole;
• an imaging system, equipped with an X-ray source assembly and a detector assembly that are arranged on the walls at the same side of the second rotating accessory, symmetrically along a shaft center;
• the X-ray source assembly and the detector assembly are fixed at the second rotating accessory;
• the detector assembly receives emergent rays from the X-ray source assembly;
• and a turbine assembly, arranged on the first rotating accessory in a slanting direction;
• a gearwheel engaged with the turbine assembly is fixed on the side of the rack that is not the side where the first rotating accessory is;
• the first rotating accessory, rack, gearwheel and second rotating accessory have coincident axes;
• the turbine assembly, with the help of a motor, drives the cage-type rotating member to rotate around the gearwheel;
• a cable, through the cage-type rotating member, connects the power source and the imaging system.
