Background

Tumor radiotherapy is a local treatment for tumors using radiation. The radiation includes alpha, beta and gamma rays generated by radioactive isotopes, and x-rays, electron beams, proton beams and other particle beams generated by various x-ray therapeutic machines or accelerators. About 70% of cancer patients require radiation therapy in the course of cancer treatment, and about 40% of cancers can be cured by radiation therapy. The role and position of radiotherapy in tumor treatment are increasingly prominent, and the radiotherapy has become one of the main means for treating malignant tumors. Radiation therapy has been in the history for decades, but has progressed faster. With the help of the development of the CT imaging technology and the computer technology, the current radiotherapy technology is developed from two-dimensional radiotherapy to three-dimensional radiotherapy and four-dimensional radiotherapy technology, the radiotherapy dose distribution is also developed from point dose to volume dose distribution, and the dose intensity adjustment in the volume dose distribution is realized. The current mainstream of radiotherapy technology includes stereotactic radiotherapy and stereotactic radiosurgery. The stereotactic radiotherapy comprises three-dimensional conformal radiotherapy and three-dimensional conformal intensity modulated radiotherapy; the stereotactic radiosurgery comprises an X knife, a gamma knife and a wave-emitting knife, and the X knife, the gamma knife and the wave-emitting knife belong to the field of stereotactic radiotherapy, and are characterized by three-dimensional, small-field, cluster, fractional and large-dose irradiation, which requires higher positioning precision and faster attenuation of dose outside a target area.
