| Outline of Final Research Achievements |
The purpose of this research is to develop a radiographic image tracking system to track respiration-induced tumor motion in real-time for adaptive tumor following radiation therapy. The tracking system will be able to provide conformable tumor motion information and allows the treatment device to accurately deliver high-dose conformable radiation to the moving target during the treatment.
In this research project, a kernel-based algorithm and a level set method-based method have been developed for tracking the tumor’s position and its boundary in kilo-voltage (kV) images and megavoltage (MV) images. The experimental results performed on the phantom and clinical data sets demonstrated the effectiveness of the systems for clinical application.
