160. Kilovoltage rotational radiotherapy of breast cancer with synchrotron radiation: A phantom study with 100 keV and 6 MV VMAT dose delivery

Purpose We proposed a new technique for breast cancer rotational radiotherapy using kilovoltage synchrotron radiation (SR) [ [1] Di Lillo F. et al. Towards breast cancer rotational radiotherapy with synchrotron radiation. Phys Med 2017;41:20–5. Google Scholar ]. Here, we compared 2D dose distributions in a breast phantom at 6 MV in circular orbit Volumetric Arc Therapy (VMAT) with respect to 100 keV irradiation in rotational radiotherapy with...
