Application and prospect of optical surface imaging technique in radiotherapy / 中华放射肿瘤学杂志

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.
