Abstract

A cutting edge real-time tracking delivery system was evaluated for respiratory-correlated radiation therapy. The performed evaluations included Multi-Leaf Collimator (MLC) leaf position accuracy, MLC motion time delay, dosimetric performance, and tracking failure. The experiment-based results indicated that the dynamic MLC was capable of achieving the position accuracy in 1~2 mm and the MLC time delay in the range of 100 s. The dosimetric comparison evidenced the significant advantage when utilizing real-time tracking. The analysis of experiments also indicated the potential fail of tracking due to the impact of patient breathing patterns and the visibility of tumour.
