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 to reduce costs and improve patient outcomes [3][4][5]. Group 1: Technological Advancements - The strong flow heavy ion accelerator in Huizhou, Guangdong, has achieved full beamline connectivity, providing the highest international pulse flow intensity of heavy ion beams and a high-precision nuclear mass spectrometer [2]. - The team has developed a compact optical design and an innovative gradient extraction scheme, reducing the circumference of the accelerator from 56 meters to 35 meters, thus decreasing the footprint to one-third of the original size [3]. - The medical superconducting strong flow ion source developed by the team achieves a beam intensity of 1 milliampere, over three times the international highest level, enhancing treatment capacity [4]. Group 2: Clinical Application and Impact - The research team aims to make the heavy ion treatment device smaller and more efficient, with the goal of making it accessible to more hospitals and patients [3][4]. - The intelligent beam delivery system allows one rotating beamline to connect to eight treatment rooms simultaneously, improving treatment efficiency and reducing patient wait times [4]. - The development of the cost-effective heavy ion accelerator treatment device is expected to enter clinical trials by the end of next year, marking a significant step towards broader patient access [4]. Group 3: Future Prospects and Collaboration - The initiative emphasizes the importance of open sharing of research resources to involve more enterprises and accelerate the application of cutting-edge technologies [4]. - The strong flow heavy ion accelerator is positioned as a key infrastructure for various fields, including basic science, medical devices, energy, and agriculture, with implications for addressing long-standing scientific questions and improving everyday life [7].
