Motion precision verification die body of six-dimensional radiotherapy bed

The utility model relates to a six-dimensional radiotherapy bed motion precision verification die body. A plurality of radiotherapy mark points are arranged in the verification die body. The verification die body is made of a low-density non-metallic material, and the radiotherapy mark points are high-density metal balls with the diameter not larger than 2 mm. And the verification die body is arranged on the six-dimensional moving mechanism. The beneficial effects of the utility model are that the verification die body provided with a plurality of radiotherapy marking points is adopted, the radiotherapy marking points are naturally distributed, position information close to practicality can be provided, the verification die body can be moved in all directions through the six-dimensional moving mechanism, and technical conditions are provided for verifying the motion precision and reliability of the six-dimensional radiotherapy bed. 本实用新型涉及一种六维放疗床运动精度验证模体，所述验证模体内设有多个放疗标记点。所述验证模体是低密度非金属材料的验证模体，所述放疗标记点是直径不大于2mm的
