电子射野影像系统在放疗中的应用进展

Advances in the application of electronic portal imaging device in radiotherapy

电子射野影像系统已成为放疗质量控制和质量保证的重要设备之一，可用于摆位误差验证分析、加速器本身日常质量控制、剂量验证、实时剂量验证等放疗质控指标的采集分析，以保障放疗实施的准确性。笔者就电子射野影像系统在放疗中的应用研究进行简要综述。

Electronic portal imaging devices have become important equipment for radiotherapy quality control and quality assurance. They can be used to verify positioning errors and other quality control indicators. They can also be applied in the daily quality control of the accelerator, dosimetry, and real-time dosimetry to ensure the accuracy of radiotherapy implementation. In this paper, the application of electronic portal imaging devices in radiotherapy is briefly reviewed.
