Abstract：Currently, image-guided radiation therapy (IGRT) is the most advanced technique in the field of radiation oncology. However, the most commonly used image-guided techniques, such as cone beam computed tomograhpy (CBCT) and electronic portal imaging device (EPID) are limited due to extra radiation, poor image quality and failure of real-time monitoring. Optical surface imaging technique generates no additional radiation and can conduct real-time monitoring. Multiple researches have demonstrated that it has significant advantages in terms of guiding positioning, real-time monitoring of the fractionated and divided motion, reducing the frequency of CBCT scanning, breathing door control, etc. In this paper, this novel technique and its application prospect in radiotherapy are reviewed.
