摘要确定论方法是一种计算精度高、速度快的基于光子-电子耦合输运求解的数值计算方法，近年来在光子放疗剂量计算中得到了广泛应用，然而该方法被引入放疗领域的时间较短，国内学者对其研究较少，对其特性缺乏全面的了解。本文对确定论方法的原理、发展现状及其临床应用进行综述，为相关研究的开展提供参考。

abstractsDeterministic method is a numerical calculation method based on photon-electron coupled transport with high computational accuracy and speed, which has been widely applied in photon radiotherapy dose calculation in recent years. However, this method has been introduced into radiotherapy for only a short period of time, which has been rarely studied in China, and systematic understanding of its characteristics is still lacking. In this article, the principles of deterministic method, current development state and clinical application were reviewed, aiming to provide reference for carrying out relevant research.
