Abstract
To provide a particle beam therapy device that expands an irradiation field while avoiding an increase in size of a scanning unit or an irradiation device including the scanning unit. A shift unitis provided downstream of a scanning unit. The shift unitdeflects a carbon beam as a particle beam to shift the irradiation field, thereby forming an expanded irradiation field. The shift unitincludes a first shift electromagnetthat shifts the irradiation field in a Y direction and a second shift electromagnetthat shifts the irradiation field in an X direction. The scanning unit is dynamically controlled, and the shift unitis statically controlled.
