Hokkaido University and Hitachi, Ltd. (Hitachi, Japan) announced that the development of the new proton-line cancer treatment system has been selected as the "top-level research and development support plan" national project in Japan, and the two sides have signed a joint development agreement. According to the agreement, Hitachi will deliver the system to Hokkaido University in 2014.
According to reports, "the most advanced research and development support plan" is an important science and technology plan in Japan, and a total of 565 projects are applied throughout Japan. At the comprehensive science and technology conference in March 2010, 30 "core researchers and research topics" that could undertake the future mission of Japanese science and technology were selected. In the application project from Hokkaido University, the professor of medical research, Bai Tubo Shu, was selected as the “Molecular Tracking Radiation Therapy Device for Sustainable Developmentâ€. This is the only project selected in the field of radiology, and it has attracted attention from Japan and abroad as a project to promote the development of radiation therapy and cancer treatment technology in Japan in the future.
The project will combine Hokkaido University's "moving object tracking technology" with Hitachi's "point scanning illumination technology", and jointly develop "small high-performance protons capable of high-precision proton beam irradiation on tumors whose position is changed due to breathing or the like. Line Cancer Treatment System." A proton-line cancer treatment facility that can be installed in Hokkaido University Hospital will be built. The facility is scheduled to begin construction in 2011 and will be completed in March 2014 as a new facility for Hokkaido University Hospital for therapeutic use.
Can also be used for moving parts
According to the release data, proton therapy is one of the methods of radiotherapy for cancer. Accelerators can be used to accelerate protons to high speeds and treat cancer by concentrated irradiation of tumors. The patient has almost no pain during treatment and does not damage the body function and morphology. Therefore, this method can be taken care of and normal life, and it is concerned about ensuring quality of life (QOL: quality of l).
According to the release of the data, it is not difficult to perform spot irradiation treatment with concentrated irradiation in a site where the brain tumor or the like does not change its position. On the other hand, since tumors in the trunk parts such as the lungs and the liver are changed in position due to factors such as respiratory movement, it is highly desirable to develop a technique capable of grasping the tumor position in real time and accurately performing radiation irradiation.
For more than half a century, Hokkaido University has been developing technologies that can concentrate radiation on important tumor sites in radiation therapy. Clay has developed a "moving object tracking technology" that automatically grasps the position of the gold mark placed near the moving tumor by X-ray fluoroscopic image, and only performs radiation irradiation when the tumor reaches a predetermined position. The "world's first" four-dimensional X-ray treatment device using this technology has also been successfully developed. According to the release data, the internal organs that change position due to factors such as respiratory movement can be grasped in the same way, and the tumor position can be grasped in real time through the image to accurately perform radiation irradiation.
Hitachi previously acquired technology and experience in accelerators and radiation exposure and control through the power system business, and used these technologies to advance the development of proton cancer treatment systems. In May 2008, the company put the "spot scanning irradiation technology" that can accurately irradiate protons according to the shape of a tumor. Hitachi also introduced the system to the general hospital for the first time in the world, and delivered it to the world's largest cancer specialist hospital, the US MD Anderson Cancer Center.
