The passive beam delivery system in the superficially-placed tumor therapy terminal at Heavy Ion Research Facility in Lanzhou (HIRFL),which includes two orthogonal dipole magnets as scanning system,a motor-driven energy degrader as range-shifter,series of ridge filters as range modulator and a multileaf collimator,is introduced in detail.

A scattering proton beam delivery system for conformal therapy and intensity modulated therapy is described.

The conformal radiotherapy techniques mainly include the two systems that are beam delivery and treatment planning.

The merit can be realized with the aid of the beam delivery system, whose functions are energy adjustment, energy modulation, beam spreading and collimation.
