1. 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.
