The development of new methods of treatment of oncological diseases is an extremely important area of modern medicine. The problem of any existing methods of treatment is that all of them, in addition to destroying tumors, kill a large number of healthy cells and tissues. But researchers from the Novosibirsk Institute of Nuclear Physics. GI Budker created a high-frequency “gun” for the therapy of oncology, which has significantly less harm to the human body, preserving the effectiveness against cancer cells.
The work on creating a new method of therapy is carried out within the framework of the direction “Development and use of sources of electromagnetic radiation based on relativistic electron beams”, and the main task is to obtain an electron beam of the required parameters with small dimensions and small spreads in velocities. According to Nikolai Vinokurov, head of the research laboratory of the Institute of Nuclear Physics,
“We are doing now and bringing a new completely electronic gun – a high-frequency electron gun, which will increase the radiation power at our facility by literally an order of magnitude, this, of course, is a big leap. At the present time, diagnostic equipment is being created to check the parameters of the electron beam, systems are being improved that transport electrons from the source to the place where they are used to generate radiation. ”
In 2017, the effectiveness of the new method was effectively tested in animals. It was studied how the body responds to the effect of therapeutic radiation doses.
“If X-ray irradiation is done with a” net “of small X-ray beams, then its effectiveness increases: harmful cells are destroyed, and the useful ones are significantly less affected. An electron beam in a free-electron laser is used to generate X-ray and terahertz radiation, and a method for treating cancer tumors using micro-beam X-ray therapy is being developed. “
