Abstract Objective To study the probability safety assessment to analyze and evaluate radiation error risk in the external beam radiotherapy, so as to establish and strengthen the control and management of the radiotherapy process, continuous improvement of quality control and quality management. Methods To build the whole of radiotherapy flow chart and process tree, using the decision tree model to determine critical control points in the whole process, making risk assessment chart and analyzing 4 patients with potential safety hazards error. Results The whole process is divided into 22 missions in 3 functional areas, the entire cover 15 branches and 59 key and 11 key control point. The enumeration of error as risks and critical control points has certain correlation. Conclusions Probabilistic safety assessment method have strengthened manage, analyze and control to risk, and all these provide the basis for developing and improving radiotherapy process control management. Radiotherapy quality management for future multidisciplinary and high-level management personnel who take up provides a prospective study.
