(See page), set the patient on the treatment table, then irradiate X-rays from two directions at right angles, and from the image from the image intensifier, the deviation from the setting at the time of treatment planning is three-dimensional. I calculated it and corrected it with the movement of the treatment table. Further, in the image by X-ray, it is difficult to determine the detailed state of the affected part such as internal organs, so the position of the affected part is aligned with the irradiation center based on the position of the bone or the like.

となり、コストを引き上げるという問題もある。In the above-mentioned prior art, since it is necessary to position the patient and the X-ray irradiator has to be arranged in the charged particle irradiator for medical use, the irradiator becomes large in size. There is. There is also a problem that it takes time to position the patient and the treatment time becomes long. Further, as the treatment table, a treatment table capable of three-axis parallel movement and three-axis rotation and capable of precise positioning is required, which causes a problem of increasing cost.

る。The above object is to provide means for increasing the energy of a therapeutic charged particle beam during positioning of a patient, irradiate the patient, transmit the beam, and measure the energy to measure the affected area from X-rays. This is achieved by obtaining a clear image of the affected area, specifying the affected area position from the image of the affected area, and irradiating the affected area only with a beam based on the affected area position information.

Further, since the position of the affected area is specified based on the obtained image and the treatment beam is irradiated, high accuracy is not required for positioning, the positioning time can be shortened, and the treatment time can be shortened. Further, since the positioning of the treatment table does not require high accuracy, it is possible to reduce the cost of the treatment table.

It is a flow chart showing a control method of this charged particle irradiation device. The electromagnet power supply 21 is controlled by the electromagnet power supply control device 20 according to the set excitation amount to excite the scanning electromagnet 2 and the scanning electromagnet 3. Then, the charged particle beam 4, which has been increased in energy enough to pass through the patient 6 and the treatment table 7, is incident on the irradiation device 1. This energy of the charged particle beam 4 is about 270 MeV in the case of proton,

域の密度分布を測定する。The data processor 16 calculates the energy loss from the incident energy and the measured beam energy, and calculates the internal density distribution of the patient 6 from the energy loss amount. Since there is a difference in the density distribution between the normal tissue and the affected area, the affected area can be identified. When there is an affected part, the position of the affected part is recorded in the storage device 18. The above procedure is repeated over the entire area to be investigated, and the density distribution of this entire area is measured.

することができる。At the time of treatment, the electromagnet is excited on the basis of the excitation amount data obtained by the above procedure and the treatment beam is made incident so that the beam can be accurately irradiated only to the affected area. According to this configuration, since the position of the affected area can be known without using the X-ray irradiation device, the irradiation unit can be downsized by eliminating the X-ray irradiation device. Moreover, since it is sufficient to irradiate the affected part position examined by the charged particle beam itself with increased energy with the therapeutic beam with weakened energy, the treatment time can be shortened, and the X-ray tube, image intensifier,
A treatment table capable of precise positioning becomes unnecessary, and the cost can be reduced.
