Charged-particle beam irradiation method and system
First Claim
1. A charged-particle beam irradiation system for an affected part in which while a charged-particle beam ejected from an accelerator is scanned by an electromagnet onto the affected part, each layer of the affected part resulting from division of the affected part into a plurality of layers in a direction of progression of said charged-particle beam is irradiated with the charged-particle beam, the system comprising:
- changing means for changing an energy of said charged-particle beam in accordance with a layer of the plurality of layers to be irradiated with said charged-particle beam; and
intensity control means for controlling an intensity of the charged-particle beam.
