中国自主研发光子计数能谱CT获批上市 入驻医院进行临床医学研究

Core Insights - China has achieved a significant breakthrough in medical technology with the approval of the first domestically developed photon-counting spectral CT, uCT Ultima, by the National Medical Products Administration (NMPA) [1] Group 1: Technology Advancement - Photon-counting spectral CT is recognized as a revolutionary direction for next-generation CT technology, offering higher spatial resolution imaging, direct multi-energy spectral imaging, and lower radiation dose imaging compared to traditional CT [2] - The pixel area of the detector in the new photon-counting spectral CT has been reduced to one-ninth of the original size, allowing for the visualization of finer pathological structures [3] - The technology has achieved a significant reduction in radiation dose, with reductions of 60% to 70%, and in some organs, reductions can reach 80% to 90%, enhancing patient safety during CT scans [3] Group 2: Collaborative Development - The project was led by United Imaging Healthcare in collaboration with several institutions, including Fudan University Zhongshan Hospital and Shanghai Jiao Tong University School of Medicine, leveraging their strengths in system design, clinical application, and testing [2] - United Imaging Healthcare has become the first Chinese company to commercialize photon-counting spectral CT globally, marking a significant milestone in the industry [2]
