[0065] In the present invention, when a patient is in a lying position for a CT scan, it is usually necessary to block the rest of the patient's body except for the examination area to improve the detection accuracy;

[0066] First, unlock the self-locking sliders 412 on both sides according to the part of the patient that needs to be covered, and then pull the curved plate 414. At this time, the curved plate 414 follows the self-locking sliders 412 on both sides and moves horizontally along the transverse guide rails 411 until the curved plate 414 moves to the set position;

[0067] Then, the handwheel 49 of the front control component or the rear control component is turned. The rotation of the handwheel 49 drives the worm 46 to rotate. The rotation of the worm 46 drives the worm wheel 45 to rotate. The rotation of the worm wheel 45 drives the gear 44 to rotate. The rotation of the gear 44 will control the ring gear 43 to drive the movable arc plate 42 to move upward along the guide wheel and rotate out from the upper end of the arc plate 414. At this time, the arc baffle 5 moves with the movable arc plate 42 until the arc baffle 5 moves to the top of the annular cover plate 36, thereby completing the covering of the part of the patient that needs to be covered inside the annular cover plate 36.
