Description

technical field

[0001] The invention relates to the technical field of using optical means to test or analyze positioning accuracy, in particular to a method and a device for judging the positioning accuracy of important parts of medical equipment by using infrared laser propagation characteristics. The method and device of the invention are particularly suitable for checking the positioning accuracy of equipment related to medical radiotherapy. Background technique

[0002] In the field of medical radiation therapy, X-rays and γ-rays produced by medical linear accelerators, Co60 treatment machines, and γ-knife have important therapeutic effects on killing cancer cells and inhibiting the spread of cancerous sites. However, radiation must be confined within the lesion range during treatment. If the positioning error of these devices is too large, the range of radiation exposure will be inaccurate, and the side effects on normal human tissues and dangerous organs will also be ...
