Patent ID: 7603164

Claim:
A composite system for radiation therapy, comprising: a CT scanner for checking the position of an affected portion of a patient to be irradiated; an irradiation apparatus for therapy, for disposing, on the basis of positional information of the affected portion checked by said CT scanner, the patient at a specific position at which the affected portion is aligned to an irradiation position, and performing irradiation to the affected portion; an X-ray simulator; a common bed used for said CT scanner, said irradiation apparatus and said X-ray simulator, in a state that the patient lies on said common bed, said bed including a positional adjustment means to allow the positional adjustment of a top plate of said common bed in a lateral direction, in a longitudinal direction and in a height direction; means for moving the patient from said CT scanner to the specific position of said irradiation apparatus and further moving the patient on said common bed to a specific position of said X-ray simulator; wherein said means for moving comprises a moving mechanism for linearly moving said CT scanner and said common bed; and said moving mechanism comprises a linear moving mechanism for said CT scanner, and a linear moving mechanism for said common bed, said linear moving mechanisms being disposed such that the movement directions of said CT scanner and said common bed cross each other, wherein said CT scanner is disposed in parallel to said irradiation apparatus, said irradiation apparatus is disposed in parallel to said X-ray simulator, and said common bed is linearly movable through its linear moving mechanism between said CT scanner, said irradiation apparatus and said X-ray simulator.
