摘要： A particle beam irradiation system comprising a first deflector having the maximum deflection amount which enables to move a particle beam in one direction to the maximum width of a target and a second deflector having the maximum deflection amount is less than the maximum deflection amount of the first deflector performs a control in which the particle beam is moved by increasing at least a deflection amount of the second deflector when the particle beam is moved, and performs a deflection substitution control in which a deflection of the second deflector is substituted to a deflection of the first deflector by decreasing the deflection amount of the second deflector and changing a deflection amount of the first deflector so as to make a position of the particle beam in the target dwell when the particle beam dwells.

摘要： There is provided a particle beam therapy system that can rapidly change beam energy without increasing the size of a deflection electromagnet even in the case where the number of required beam-energy changes is large.There is provided a plurality of beam energy changing units each provided with a beam energy attenuation unit; a beam is deflected in such a way as to sequentially passes through the plurality of beam energy changing units; while a beam passes through one of the beam energy changing unit, the beam energy attenuation amount of another beam energy changing unit is changed.
