Similarly, in the case of treatment with ion beam α,
The ion particle beam α generated by the ion particle beam generation and acceleration device 1b is applied to the tumor of the human body positioned on the treatment table 9 via the transport electromagnet 2b and the common irradiator 3.

At this time, as shown in FIG. 6, compared with the electron beam β and the X-ray γ, the irradiation dose of the ion particle beam α (proton beam) can be peaked in tumor cells deep in the human body. . Further, as shown in FIG. 7, when a heavy ion beam α of carbon or the like is used, the irradiation effect ratio RBE to biological cells per unit dose is relatively advantageous, and the ratio of normal cells to oxygen The low radiation effect ratio OER with tumor cells is advantageous and allows more effective treatment.

That is, by adjusting the irradiation time and the number of irradiations of each beam according to the requirements of the case of each individual patient, the irradiation can be efficiently performed by making use of the advantages of the two, and the building size and the building size can be reduced by the compact structure. The cost can be suppressed, and the building and maintenance costs of the building can be reduced.

Although the case where the configuration of the third embodiment (see FIG. 3) is applied to the radiation therapy apparatus has been described here, the first embodiment (see FIG. 1) and the second embodiment (see FIG. 2) are used. ), Even if the configuration of Embodiment 4 (see FIG. 4) is applied,
It goes without saying that each of them has the same effect.

By adopting α for treatment, a treatment plan and the like can be shared, and a radiotherapy apparatus that can be easily treated at low cost can be realized.

Further, it is needless to say that the respective functions and effects can be obtained by arbitrarily combining the embodiments.
