A system and method for following lung cancer radiotherapy tumor movement

Abstract

A lung cancer radiotherapy tumor movement following system and method, belonging to the field of medical equipment, discloses a lung cancer tumor respiratory movement following method based on four-dimensional radiotherapy, and supporting equipment. Through the cooperation of the equipment and the method, the operation position of the patient is realized. The positioning is fixed, which realizes the ultimate adjustment of the radiation head, and the cooperation of the two realizes the fast, accurate and effective tracking and pointing of the lung cancer tumor respiratory movement of the radiation head patient, the processing speed is fast, the radiation exposure efficiency is high, and the side effects caused by radiation Less, high degree of automation, remarkable effect.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to radiation therapy, in particular to a tumor motion following system and method for lung cancer radiation therapy. Background technique [0002] Radiation therapy is tumor radiation therapy, which is a local treatment method for tumors with radiation. About 70% of cancer patients need radiation therapy during the treatment of cancer, and about 40% of cancers can be cured by radiation therapy. Radiation therapy Its role and status in tumor therapy have become increasingly prominent, and it has become one of the main means of treating malignant tumors. The principle of radiotherapy is to use different tissues and organs and various tumor tissues to respond to changes after receiving irradiation, that is, radiosensitivity, some tumors have small early tumor volume, good blood supply, and high oxygen content in tumor cells. , high radiosensitivity, at this time the tumor cell...
