A beam irradiation target confirmation device (1) has an X-ray switching irradiation processing unit (6a) for radiating at least two types of X-rays by a perpendicular X-ray irradiation unit (13) through use of an energy switching unit (11), a perpendicular X-ray detection unit (14) for detecting X-rays radiated from the perpendicular X-ray irradiation unit (13), a pre-treatment confirmation image creation processing unit (7) for creating pre-treatment confirmation images (20B, 20C) on the basis of detection information of the at least two types of X-rays acquired by the perpendicular X-ray detection unit (14), a reference image acquiring unit (3) for acquiring a reference image (20A) obtained in a treatment planning stage, a comparison processing unit (8a) for comparing the pre-treatment confirmation images (20B, 20C) and the reference image (20A), and a result output unit (4) for outputting a comparison result obtained by the comparison processing unit (8a). A beam irradiation target confirmation device for treatment is thereby provided, whereby a condition inside the body of a treatment subject can be measured and the need for changing a treatment plan can be determined easily and with low radiation exposure. |
