AbstractA 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.
