Described bed board is made by non-radioprotective class material, and the protective cover cambered surface of portion, shield plane base plate all expose to protective cover system and be fixed as one by lead nail and support bed end to end.
Described protective cover A is identical with protective cover B size shape material, all by ten wide be that the semicircle sheet lead circle of 20cm is as a whole by crumple chain link combination, described protective cover A is connected with crumple casket a near the head of a bed one side, opposite side is provided with power ring a, described protective cover B is connected with crumple casket b near tailstock one side, and opposite side is provided with power ring b.
Described power ring a and power ring b are respectively equipped with crumple driver a and crumple driver b, and two side bottoms are respectively equipped with ball wheel a and ball wheel b, and power ring a, power ring b are identical with semicircle sheet lead circle size shape material.
Described crumple supporting plate is fixed in support bed both sides, is in same horizontal plane with support bed bed surface, and the crumple supporting plate is provided with the slide rail race, and the side is provided with Position Scale; Described ball wheel a, ball wheel b are stuck in and keep free rolling condition in the slide rail race.
Described radiation does not hinder the width in district, is equal to the relative distance of power ring a and power ring b.
The beneficial effect that the present invention has is:
Novel structure of the present invention, the scanning area that the volume chain type is regulated the CT beam effectively reduces CT scan to the additional injury of human body.
