%X This document is a multi particle combined biological conformal intensity modulation therapy plan, which is based on multi-modal medical images such as PET-CT and f-MRI for radiotherapy plan design. Dual localization (CT and f-MRI or CT and PET-CT) or triple localization (CT and f-MRI and PET-CT) and target area delineation through image fusion have shown the advantages of target area delineation based on functional images through previous studies. The adopted X-ray radiotherapy plan has relatively large damage to normal tissue and uneven dose distribution. Compared with the homoplasmon and heavy ion plans, it clearly shows that the proton and heavy ion target area design is more reasonable than the photon target area design, the dose distribution is more uniform, the radiation field is more reasonable, and the surrounding normal tissue dose is significantly reduced, with obvious advantages
