The corpuscular rays ( the electric charge heavy particle radio ) treatment is the general term of the radiotherapy which cures a malignant tumor mainly by irradiating the beam of the corpuscular-radiation of proton and baryon ( the heavy ion ) and so on to the focus.
In the kind of the particle to use, it is divided into the proton line treatment, the baryon ( the heavy ion ) line treatment and the pion radiotherapy and so on and clinical application and a research are done in each place in the world.
For example, in the proton line treatment, it is the atomic nucleus of the hydrogen atom and it irradiates the one to have made high-speed by accelerating the proton which has a positive electric charge to the interior of the body.
These are the one which is developed, making the clinical experience of the irradiation radiation treatment a basis out of using an X ray and a gamma beam ( gamma ray ) but are expected as the cure which has the characteristic which suited the treatment of the cancer.
The corpuscular rays treatment is the cure to irradiate by narrowing down aim to the target which calls the proton line and the baryon ( the heavy ion ) line which is gotten from the actuator of the cyclotron and the synchrotron and so on cancer.
The characteristic of the one ( the electric charge heavy particle radio ) which has an electric charge out of the corpuscular rays is the fact not to advance towards above the depth which is constant and the fact to act most strongly about some depth.
To center the effect on the cancer focus compared with the photon line in the proton line and the baryon ( the heavy ion ) line from these characteristics becomes easy.
Therefore, without bringing about the side effect which is strong in the organization around the cancer focus, the enough dose can be irradiated.
It thinks that it does </span> which suits the treatment of the becoming localized cancer focus that <span style="color:#FF00FF;"> isn't progressing because the proton line and the baryon ( the heavy ion ) line become localized in the cancer boiling and it is possible to be irradiated by them.
The effectivity seems to be able to be especially shown by the treatment when there is an organization which is weak about the ray in the neighborhood of the cancer.
The effectivity which makes a pair a malignant melanoma in the eyeball, the chordoma and the chondrosarcoma to have formed in near the central nerve system, the head and neck cancer, the I period non- cellule lung cancer, the liver cell carcinoma, the prostatic cancer of the part and so on from the results so far becomes clear.
