<p>The present invention provides a laser verification device for use with a multi-source radiotherapy equipment. The multi-source radiotherapy equipment comprises multiple radiation sources, multiple collimators and a therapy bed. The multiple radiation sources are arranged in one-to-one correspondence to the multiple collimators. The laser verification device comprises: a positioning plate, fixed on the multi-source radiotherapy equipment and arranged between the radiation sources and the collimators; a movable plate, arranged on and movable relative to the positioning plate, and provided with multiple first mounting holes and multiple second mounting holes which are spaced apart from the multiple first mounting holes, the movable plat being used for switching the multiple first mounting holes or the multiple second mounting holes to positions corresponding to the multiple collimators; multiple laser emitters, arranged in the multiple second mounting holes respectively; and a collector-analyzer, arranged on the therapy bed and used for collecting beams emitted from the laser emitters and performing data analysis.</p> |
