胸腹部肿瘤放射治疗呼吸运动预测算法的研究

A study on prediction algorithm for respiratory movement in the radiotherapy of thoracic and abdominal tumor

在胸腹部放射治疗中,由于呼吸运动会影响放射治疗精度,故采用实时跟踪技术,其为现代精确放射治疗中有效的解决方法。综述实时跟踪放射治疗中用来补偿系统响应延时的呼吸运动预测算法,并比较各种算法的特点、性能及发展现状,展望未来实时跟踪技术的发展及趋势。

Due to the influence of respiratory movement in thoracic and abdominal radiotherapy, the real-time tracking technique was effective solution in the contemporarily precise radiotherapy. This article summarized prediction algorithm of several respiratory movement that was used to compensate the delay caused by system response in the real-time tracking radiotherapy, and compared the characteristics, performance and developing situation of various algorithm, and prospected the development and tendency of real-time tracking technique in future.
