Abstract:: The radiation-free and unmarked body surface monitoring technology is developed for reducing the additional radiation dose generated by positioning error verification during radiotherapy positioning, and further reducing the positioning error and monitoring the displacement deviation of patients during radiotherapy in real time. At present, the widely used optical surface guided radiotherapy technology is also a type of radiotherapy guided by body surface monitoring. The system mainly uses optical imaging equipment as a tool to complete body surface scanning, three-dimensional reconstruction, real-time monitoring, etc., thereby assisting doctors to carry out radiotherapy more accurately. Herein the study elaborates on the methods, technologies and research results of guided radiotherapy from the aspects of body surface markers, three-dimensional surface imaging systems and mobile devices, and provides prospects for future researches.
