| Outline of Final Research Achievements |
In radiation therapy, intra-fractional tumor motion significantly limits the efficiency of radiation delivery and brings potential risk for organs around the tumor. Conformable tumor following beam control is an ideal solution for such intra-fractional motion problem. In this study, two key techniques of real-time markerless tumor tracking and motion prediction have been developed for such accurate beam control that can be implemented on radiotherapy instruments widely used in clinic. Experimental results demonstrate that the proposed techniques outperform the conventional methods and more importantly, they can achieve clinically useful performance.
