Helium ion therapy
WebCarbon ions can be used for heavy ion therapy, offering highly conformal dose distribution due to an even sharper Brag peak and potentially greater biologic effectiveness as compared with photons and protons. The high-linear energy transfer of carbon ions makes this modality intriguing for use in malignancies radioresistant to photon therapy. Web1 mei 2024 · HEATHER - HElium Ion Accelerator for RadioTHERapy Full Record Related Research Abstract A non-scaling fixed field alternating gradient (nsFFAG) accelerator is being designed for helium ion therapy. This facility will consist of 2 superconducting rings, treating with helium ions (He²⁺ ) and image with hydrogen ions (H + 2 ).
