杨建成：推动重离子治疗系统惠及更多患者（迈向“十五五”的创新图景）

Core Viewpoint - The development of a cost-effective heavy ion accelerator treatment device is crucial for enhancing cancer treatment accessibility and efficiency in China, leveraging advancements in technology and infrastructure [2][3][4]. Group 1: Technological Advancements - The strong flow heavy ion accelerator in Huizhou, Guangdong, has achieved full beamline connectivity, providing the highest international pulse flow of heavy ion beams and a high-precision nuclear mass spectrometer [2]. - The research team has developed a compact optical design and an original gradient extraction scheme, reducing the circumference of the synchrotron accelerator from 56 meters to 35 meters, thus decreasing the footprint to one-third of the original size [3]. Group 2: Treatment Efficiency - The medical superconducting strong flow ion source developed by the team achieves a beam intensity of 1 milliampere, which is over three times the international highest level, increasing the treatment capacity [4]. - A high-performance beam intelligent distribution system has been created, allowing one rotating beamline to connect to eight treatment rooms simultaneously, enhancing treatment efficiency and reducing patient wait times [4]. Group 3: Future Prospects - The research on the cost-effective heavy ion accelerator treatment device has made significant progress, with successful tests of the milliampere-level linear injector and stable operation of the beam intelligent distribution system [4]. - Clinical trials for the cost-effective heavy ion accelerator treatment device are expected to commence by the end of next year, with plans to promote open sharing of research resources and collaboration with international teams [4].
