Description

Technical Field

[0001] The utility model relates to the technical field of multi-leaf collimator maintenance, in particular to a maintenance tool for a linear accelerator multi-leaf collimator which is easy to adjust. Background Art

[0002] The multi-leaf collimator is an important component of the medical linear accelerator, which is used to accurately adjust and control the shape and size of the radiation beam to meet the treatment needs of tumors of different locations and shapes. The reflective spot plays a role in positioning and calibration on the multi-leaf collimator to ensure that the radiation beam can be accurately aimed at the target area.
