Conclusion:The results indicate the feasibility of VMAT treatments under tumor tracking for selected patients.The arcs available for planning influence the quality of treatment.The L partial arc plans had clinically acceptable quality in four patients.Treatments with reduced margins could be safely delivered by gating the treatment beam if the tumor motion exceeds the margins.Also, a great advantage is that the dose delivered to the tumor could be exactly monitored.
