A fluoroscopy gate controller 310 acquires the fluoroscopic images at such timing that the respiratory phase is within a predetermined range using the respiratory phase obtained by the external respiration monitor. A treatment beam gate controller 410 controls the gate of the emission of a treatment beam using the internal respiratory phase measured from the images gated and acquired by the gate imaging controller 310.
