Problems solved by technology

However, due to the large number of parameters involved in the radiotherapy planning system, and the dose of radiotherapy can only be determined through complex theoretical calculations, doctors need to repeatedly debug and optimize the parameters to meet the dose constraints, and the dose needs to be adjusted after each optimization. calculation, while the dose calculation is carried out in three-dimensional space, the calculation process is complex and time-consuming

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an accurate radiotherapy planning system. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the process of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment are becoming more and more prominent, and it has become the main means of treating malignant tumors one. [0003] Although radiotherapy has only a few decades of history, it has developed rapidly. With the help of the development of CT imaging technology and computer technology, the current radiation therapy technology has developed fr...
