Installation of proton therapy in Troitsk passes final tests

On the basis of the Institute for Nuclear Research of the Russian Academy of Sciences will soon be Center of Nuclear Medicine. The linear accelerator of protons and negative hydrogen ions serve to treat the Russians. Installation of proton therapy is already being last tests, and after its commissioning Center of Nuclear Medicine can take up to 50 patients a day.



Union physicists and doctors will give hope to patients with complex tumors — the disease would shoot a proton cannon. "This center is designed our systems, our equipment, our technologies to be implemented. Must respect the work of the people who work here and refused, perhaps many prestigious positions abroad ", — Said the assistant chief of staff for the president of Russia Ekaterina Popova.

Special sights proton-beam installation will be individualized for each patient. Without damaging healthy tissue, protons will destroy every cell tumor. "The proton beam enters the treatment room proton therapy through collimating device. It is directed at the patient, which will be posted on the positioner ", — Says Sergey Akulinichev, head of the Laboratory of Medical Physics of the Institute of Nuclear Research.

The linear accelerator of protons and negative hydrogen ions (H-anions), the so-called "meson factory" — a giant underground structure. He began to build in the 70s for fundamental research. It's pretty expensive toy for scientists. Tunnels with equipment to disperse the particles are laid under the Nuclear Research Institute.

After injection path where the proton beam is generated and focused particles fall into the linear accelerator. As traffic increases energy — protons fly faster. Then the path of the particles disperse. For example, they can be sent to the experimental complex.

Protect people from radiation pyramid of concrete slabs. The base plate is set hectare and 2.5 meters thick. This neutron source, which was built 30 years, to the delight of physicists who now works. "Scientists are very important not only adrenaline, but also the fact that they have discovered something new", — Says the head of the department of experimental complex of the Institute of Nuclear Research, Mikhail Grachev.

As soon as possible in the institute managed to create a new technology for medical isotopes for the early diagnosis of cardiac disease and cancer in the first place — strontium-82. Its breakdown products — rubidium-82 — is introduced into the human body. For the patient, this radionuclide is almost harmless, as the term of his life less than one and a half minutes. However, in order to make it, needs a small accelerator. In Troitsk developed another option — a compact generator of rubidium-82. This kind of "ambulance" with isotopes. Such devices unavailable in Europe, and its efficiency is higher than the U.S. counterpart.

"The generator, which is developed in our institute, is charging a radioactive isotope, which is produced by a linear accelerator of protons. After separation of the radioactive isotope, this isotope is placed on the ion exchange column. The ion exchange column is placed in a tungsten protect and further the generator poisoned the packaging to a medical facility ", — Says Boris Zhuikov, head of the radioisotope laboratory complex of the Institute of Nuclear Research.
