中国科学院近代物理研究所研发的新一代超紧凑旋转束重离子治疗系统（SIMM）首台示范装置已在广东省惠州重离子医学中心建成1。该装置代表了中国精准放疗领域的重要突破，采用了多项变革性技术创新1。
相比上一代设备，新装置在空间占用和能源消耗方面实现显著优化1。占地面积从4600平方米缩减至1200平方米，运行能耗降低至原来的约三分之一，而年治疗能力则由1000例提升至2000例至5000例1。目前该装置已进入设备检测阶段，预计于2026年底开展临床试验1。
国产医用重离子加速器的推广应用已取得实际成效1。首台完全自主知识产权的医用重离子加速器于2020年在甘肃省武威市正式投入临床治疗1，此后国产设备已在全国推广10台，截至2026年9月底已完成近5000例患者的治疗1。中国科学院近代物理研究所在该领域的研发工作始于1993年1，新装置的建成有望进一步降低治疗费用并推动离子放疗产业升级1。
China's Institute of Modern Physics under the Chinese Academy of Sciences has completed the first demonstration unit of a next-generation ultra-compact rotating beam heavy ion treatment system (SIMM) at the Huizhou Heavy Ion Medical Center in Guangdong Province, marking a major milestone in the country's precision radiotherapy sector 1. The newly built system represents a significant technological advancement, incorporating multiple revolutionary technologies that substantially improve treatment capacity while reducing operational footprint and energy consumption.
The demonstration device has entered the equipment testing phase and is expected to commence clinical trials by the end of 2026 1. Compared to its predecessor, the new system reduces floor space from 4,600 square meters to 1,200 square meters and cuts operational energy consumption to approximately one-third of previous levels 1. Annual treatment capacity has increased from 1,000 cases to between 2,000 and 5,000 cases, with expectations that the system will substantially lower treatment costs and drive industry-wide upgrades in heavy ion radiotherapy 1.
This advancement builds on years of development by the Institute of Modern Physics, which began related research in 1993 1. China's first domestically developed heavy ion accelerator with completely independent intellectual property rights entered clinical service in Wuwei, Gansu Province in 2020 1. Since then, ten units of domestically produced medical heavy ion accelerators have been deployed nationwide, having completed treatment for nearly 5,000 patients as of September 2026 1.
