Radiation treatment verification method and radiation treatment device

Abstract

The invention discloses a radiation treatment verification method and a radiation treatment device. The radiation treatment verification method comprises the following steps of: developing an element which is positioned on a position subjected to radiation treatment with energy meeting predetermined requirements and generated through radiation, and determining the position of the element; comparing the determined position of the element with the previously appointed radiation position, and verifying the position subjected to the radiation treatment. By means of the verification method and thedevice in the invention, developing treatment can be carried out by dint of a positron emission nucleus of the element generated after radiation, so that the position of actual radiation can be accurately determined and the purpose of verifying the radiation position is achieved; and in addition, because the information of the development can provide information on metabolism, proliferation, hypoxic state, and the like of tissues and cells, the verification method and the device are favorable for simultaneously carrying out therapy and the biological validation of living organisms by simultaneously deducing and determining the biological position and the relative biological dosage of tumor radiation according to the position and the intensity of development, and thus, the accurate three-dimensional conformal radiation therapy for organisms is realized in the real sense.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a radiation treatment verification method and a radiation treatment device. Background technique [0002] At present, the radiotherapy technology for tumors is constantly improving. In order to achieve better therapeutic effects, the requirements for the accuracy of the irradiation position and dose are getting higher and higher. The purpose is to give a large dose to the tumor area, while the surrounding Normal tissues or organs are given as little radiation dose as possible. [0003] During radiation therapy, if the irradiation position of the radiation is not accurate, it will not only fail to achieve the therapeutic effect, but may have serious negative effects, and even cause death to the patient. Therefore, the irradiation position is one of the key factors in radiotherapy. Accuracy will directly affect the effect of treatment. [0004] In order to ensure the quality of treatment ...
