Dosimetry for New Radiation Therapy Approaches Using High Energy Electron Accelerators
Frontiers in Physics, 2020 We have performed dosimetry studies using electron beams with energies up to 50 MeV, which exceed current clinical energy ranges and approaches the bottom end of the very high energy electron range. 50 MeV electron beams can reach deep-seated tumors.

Clinical application of high‐LET radiotherapy combined with immunotherapy in malignant tumors
Precision Radiation OncologyThe superior physical and biological properties of high linear energy transfer (LET), as opposed to traditional low‐LET rays, underscore the advantage of proton therapy (PRT) and carbon ion radiotherapy (CIRT) are better than traditional photon ...
