Description
Technical Field
[0001] The utility model relates to the technical field of radiotherapy, and particularly relates to a tumor radiotherapy protection device. Background Technique
[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Approximately 70% of cancer patients need radiotherapy during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment have become increasingly prominent and have become one of the main means of treating malignant tumors. When a patient undergoes radiotherapy, the entire body of the patient is in contact with the radiation, which increases the radiation dose received by the patient during a single treatment, and the radiation will damage normal cells, so the patient suffers greater damage during radiotherapy.
