The first home-grown tumor proton therapy system will be available.

(Health Times reporter Hu Danping intern reporter Cao Min)
the proton heavy ion treatment system used to deal with tumors is currently the most expensive medical equipment, its construction costs often up to billions, previously by multinational medical device giants including Siemens monopoly. But the good news is that the proton heavy ion therapy system has a domestic version.
recently, the core component of the 230MeV superconducting proton cyclotron of China Nuclear Group completed the acceptance of the source, becoming China's first advanced medical device with independent intellectual property rights for proton therapy of malignant tumors. It is reported that this superconducting proton cyclotron is scheduled to be installed around 2018, gradually into the clinical testing process.
Proton Therapy is the world's leading cancer radiation therapy technology. In advanced developed countries, proton-heavy ion interventiononcology treatment is nothing new.
According to Xu Gang, director of the radiology department of Peking University Cancer Hospital, the means of treating tumors now have radiation therapy, surgical treatment and other treatment methods for the body's local.
radiotherapy is divided into photonic therapy, proton therapy, heavy ion therapy, traditional photonic therapy such as x-ray side effects. In contrast, in proton therapy, protons will be in the body energy changes to form a "Prague peak", can be accelerated to the speed of light 70% (about 210,000 kilometers per second) into the human body, the radiation reached the tumor lesions before the energy release is not much, but when reaching the lesions, will instantly release a large amount of energy to kill tumor cells, this "stereotactic blasting" technology, the damage to normal tissue is very small, but the tumor cells will produce a powerful killing effect.
early, proton heavy ion treatment system is sky-high, and has not been introduced in China, there are many cancer patients with need for this technology must go overseas for cancer treatment.
is pleased that in May 2015, China's first proton heavy ion project, the Shanghai Proton Heavy Ion Hospital, was put into operation, investing $1.9 billion in the purchase of proton heavy ion therapy system from Siemens, with a price of 278,000 yuan for a single course.
" in terms of cost, proton heavy ion therapy is much more expensive than traditional tumor treatments, which is the biggest drawback of proton heavy ion therapy. Xu Gang said. At present, the state for proton / heavy ion tumor treatment in many aspects of the focus of support, last June it was included in the "13th Five-Year Plan" in the "ten major strategic products", the independent research and development of the tumor proton therapy instrument will undoubtedly reduce the cost of treatment.in addition to
, there are four proton heavy ion treatment institutions are being prepared or ready to open the stage: Wuhan Proton and Heavy Ion Cancer Treatment Center, Shanghai Proton Heavy Ion Hospital, Jiangsu Province Proton Heavy Ion Hospital, Zhejiang Ningbo Kangdameshan Health Industrial Park Proton Heavy Ion Hospital, 301 Hospital Hebei Ganzhou Proton Therapy Center, when the localization of proton therapy will be a major breakthrough in the field of tumor treatment.
