Japan Hokkaido University and Hitachi (Hitachi) announced that, due to the new Proton cord cancer treatment system in Japan "is selected as the most sophisticated research and development support to national projects in the planning", the two sides signed a joint development agreement.
In accordance with this agreement, Hitachi will be 2014 to Hokkaido University delivery system.According to reports, "State-of-the-art research and development support planning" is Japan important scientific technology planning, Japan total 565 items around.
In 2010, the integrated science and technology meeting, choose an affordable Japan Science and technology in the future mission of 30 "nucleus research staff and research". The candidates from Hokkaido University, Professor of medical studies clay Bo tree "development sustainability development of molecular track radiation therapy device" is selected. This is the only medical radiation is selected in the field of the project, as Japan's future radiation medical and cancer treatment technologies play a facilitating role in the project, has been focus Japan and abroad.The project will be fusion of "Hokkaido University moving object tracking technology" and "Hitachi's point scanning irradiation technology", jointly developed by both sides to high precision on location because of breathing, etc change the tumor for proton irradiation "small high performance Proton cancer treatment system" line.
Hokkaido University Hospital will be built to set the system's Proton line cancer treatment facilities. The facility is scheduled to begin construction in the year 2011, completed in March 2014, as Hokkaido University Hospital's new facilities used for therapeutic purposes.Can also be used to move the site
According to published materials, Proton line cancer treatment method is the radiation treatment for cancer, one can make use of the accelerator will be accelerated to high speed Proton, centrally through the tumor to treat cancer radiotherapy.
When patients treated with almost no pain or injury the body morphology and function. Therefore, this approach can take into account the treatment and as a normal life, to ensure the quality of life (QOL: quality of life) in the treatment of advanced cancer therapy and attention.Publications that use this kind of treatment methods, such as in brain tumor will not change the location of the site, for centralized point of exposure to radiation is not difficult.
On the other hand, because of the lungs and liver, the body parts of the tumor will vary depending on factors such as the respiratory movement and change the location, so it was urgently want to be able to develop to a real-time understanding of tumor location and accurate for radiation technology.Hokkaido University for more than half a century have been developing in the radiation therapy focuses on the radiation of important tumor location technology.
Clay has developed through x-ray perspective image automatically get into mobile tumors near Golden tag location, only the location of the tumor arriving is radiation "mobile objects tracking technology". Also successfully developed using the technology of the "world's first single," 4-d x-ray therapy device. Publishing information that can be equally because factors such as the respiratory movement and change the location of the internal organs, by image real-time understanding of tumor location, accurate to radiation.Hitachi previously through the power system operations, access to the accelerator and radiation and control techniques and experience, and to use these technologies to promote a Proton cord cancer treatment system development.
May 2008, the company makes according to tumor shape high precision irradiation Proton line "point scan irradiation techniques" practical. Hitachi also for the first time, the "global" to the General Hospital of imported using the technology of the system, to be delivered to the world's largest Cancer Hospital — the United States "M.D. Anderson Cancer Center".
