WebFLASH radiotherapy (FLASH-RT) has gained attention as an ultra-high dose rate RT in recent years. This treatment significantly shortens the time of RT and reduces the influence of tumor movement caused by breathing or other factors. In addition, it spares the surrounding normal tissues and organs while ensuring the anti-tumor effect.
