Dosimetric comparison of volumetric modulated arc therapy and intensity-modulated radiation therapy for liver stereotactic ablative body radiotherapy
Conclusion
VMAT planning for liver SABR provided measurably higher levels of dose conformality compared with IMRT. An ipsilateral partial arc, single circumferential arc, or circumferential arc with added non-coplanar partial arc proved to be the most promising arc configuration in the majority of patients.
