Abstract：
A scattering proton beam delivery system for conformal therapy and intensity modulated therapy is described. The beam is laterally spread out by a dual-ring doublescattering system and collimated by a program-controlled multileaf collimator and patientspecific fixed collimators. The proton range is adjusted and modulated by a programcontrolled binary filter and ridge filters.
