Abstract:
International studies have established that electrons, X-rays, protons, and heavy ions can all be utilized in ultra-high dose-rate radiotherapy. Among these modalities, megavoltage X-ray ultra-high dose-rate radiotherapy holds particularly broad clinical promise. With its long-term expertise in high-intensity pulsed radiation sources, the Institute of Applied Electronics at the China Academy of Engineering Physics has pioneered global solutions for generating and measuring megavoltage X-rays ultra-high dose-rate radiotherapy, positioning China at the forefront of this field. Herein, we review the development history, current status, and future trends in ultra-high dose-rate X-ray generation, measurement, and protection. The insights provided aim to serve as a reliable reference for clinical and preclinical research, equipment development, and standardization, thereby enabling more precise and reliable megavoltage ultra-high dose-rate X-ray production and measurement. We hope this work will significantly support further research and clinical translation of ultra-high dose-rate radiotherapy technology.
