Abstract： Radiotherapy is an indispensable treatment of lung cancer. However, movement of lung cancer brings challenges to precise radiotherapy. Four-dimensional cone-beam CT is a four-dimensional imaging technique, which can demonstrate the tumor trajectory to improve the accuracy of radiotherapy.In this article, the research status and development tendency of four-dimentional cone-beam CT in terms ofmeasuring and correcting set-up errors, observing variability of tumor postion and movement, guiding delineation of target volumes as well as calculating radiation dose were retrospectively reviewed.
