Abstract: [Purposes] As CT imaging equipment is an important medical imaging diagnostic equipment, this paper aims to study the development status as well as hotspots in this area, in order to provide data basis for the development of our country's CT imaging equipment technology. [Methods] This paper makes statistics and analysis of global and domestic CT imaging equipment patents, compares the current development status of domestic CT imaging equipment patents from the aspects of application trend, geographical distribution, main applicants, patent types and legal status.[Findings] By analysis, it is found that the global patent application for CT imaging equipment has entered a stable period of development, while China's patent application is still in a period of rapid development. [Conclusions] Siemens, Philips, Toshiba, General Electric and GE Healthcare still have certain advantages in the global CT imaging technology and market, but the technology development of domestic leading enterprises has achieved certain breakthroughs, and they attach importance to the overseas patent layout, which has laid a good foundation for their subsequent market development.

CT(Computed Tomography),即电子计算机断层扫描。CT利用精确准直的X线束、γ射线、超声波等,与灵敏度极高的探测器一同围绕人体的某一部位进行一个接一个的断面扫描,具有扫描时间快、图像清晰等特点,可用于多种疾病的检查。根据所采用的射线不同可分为X射线CT(X-CT)和γ射线CT(γ-CT)等[1]。
全球CT影像设备市场稳步增长,新兴市场增长更为强劲。根据相关统计数据[2],2020年全球CT市场规模达到约135.3亿美元,预计2030年将达到约215.4亿美元,年复合增长率为4.8%。欧美发达国家CT市场相对成熟,全球CT市场的主要增长动力来自亚太地区等新兴市场。其中,亚太地区2020年的市场规模为52.4亿美元,预计在2030年市场规模将达到约98.7亿美元,2020—2030年亚太地区市场规模的年复合增长率预计达到6.5%。……
