A method and apparatus for positioning a therapeutic beam in which a first distance from a first predetermined position other than an affected part of a patient to the affected part, is determined on the basis of a first image which includes at least part of the patient and which includes the position of the affected part of the patient. A second distance, from a second predetermined position corresponding to the first predetermined position to a position of the therapy beam, is determined on the basis of a second image which includes at least part of the patient and which indicates the position of the therapy beam. The patient is then moved such that the therapy beam is irradiated onto the affected part, on the basis of the first distance and the second distance.

A therapeutic apparatus comprising: irradiating means for irradiating an ionized particle beam; a therapy table on which a patient is mounted; X-ray computer tomography means for accumulating image data; means responsive to said image data from said X-ray computer tomography means for generating a first image of at least part of the patient indicating the position of an affected part; first display means for displaying said first image generated by said X-ray computer tomography means; X-ray means for generating a second image of at least part of the patient indicating the position of said ionized particle beam, said second image being a center projection image formed on a plane when the patient is projected by an X-ray radiating from a point; second display means for displaying said second image generated by said X-ray means; input means for inputting positional information indicative of locations of reference points of physical characteristics in said first image and said second image, said physical characteristics being identified on said second image and the positions of said reference points being related to the position of said affected part; computing means for calculating the distance of movement of the therapy table such that said ionized particle beam is irradiated onto said affected part of the patient on the basis of said positional information of said first image and said second image and for calculating the shape, dose, and energy of said ionized particle beam; and means for moving the patient relative to said ionized particle beam on the basis of said calculated distance.
