China ionic medical equipment

Proton therapy, as a new level of tumor radiotherapy technology, has the characteristics of good therapeutic effect, less adverse reactions and rapid recovery of patients, and is an excellent way to treat tumors internationally. Due to the high cost of introduction and operation of proton heavy ion machinery and equipment, the core technology is monopolized overseas, and China lacks proton heavy ion medical and health machinery and equipment. The research and industrial development and application of domestic proton heavy ion machinery and equipment with independent patent rights have broad market prospects.

The research team of proton therapy system in Hefei Institute of Chinese Academy of Sciences has made pioneering progress in several important links, such as component development, integrated assembly technology and system software joint debugging and testing. At present, the world's most compact nanotube rotating proton heavy ion system accelerator has been successfully developed, so a 200MeV proton beam has been successfully generated, and the technical level of the compact nanotube network accelerator is self-controllable. The current intensity of superconducting magnet is 140A/mm2, which is three times of the magnetic field of similar mechanical equipment in the world. The application of electric field has reached the highest international level 175kV/cm. The network accelerator completed the maximum magnetic field intensity of the 3.0 Tesla car;

The diameter is reduced by 25% to only 2.2 meters, and the total weight is less than 50 tons. After several months of system software adjustment, the beam generation in the diagnosis room was successfully completed, and the problem of close combination of beam transmission and precise conformal therapy was solved. The first high purity graphite energy reducer successfully developed and designed in China can adjust the kinetic energy of 70- 185CeV, the matching range is 4. 1g/cm2-22.7g/cm2, and the accuracy is 0.5CeV. The development and design of the first externally cooled bipolar iron supercritical extraction system software in China have been completed, and the design scheme of the miniaturized nanotube rotating system software has been completed, which greatly reduces the cost.

Hefei municipal government departments jointly established Hefei Zhongke Ion Company to carry out independent research and development of domestic nanotube rotary proton heavy ion system software and promote the development of proton medical and health machinery and equipment industry. A number of core technologies operated by the Institute of Plasma of Chinese Academy of Sciences have promoted the application and popularization of large and medium-sized scientific research engineering design, and promoted the application of medical and health machinery and equipment such as nanotubes, magnetic fields and ultra-low temperature, serving? Physical and mental health China? Strategy and the development trend of the domestic health industry, the project that serves the main position of economic development and the health of ordinary people.
