    “…VMAT and IMRT treatment plans using either 6‐ or 10‐MV photon energies were generated through automatic SBRT planning software in the RayStation treatment planning system. RESULTS: For planning target volume, there was no difference in D (95%) for all plans, whereas D (2%) and D (50%) were significantly increased by 5.22%–5.98% and 2.47%–2.59%, respectively, using VMAT(6/10‐MV) plans compared to IMRT(6/10‐MV) plans. …”
