According to CCTV News on July 22, the nuclear magnetic resonance instrument led by the Chinese Academy of Sciences Shenzhen Institute of Advanced Technology has been successfully developed and has begun mass production. This instrument can obtain the whole body image of the human body, which not only improves the resolution, but also accelerates the imaging speed.

What are the difficulties in independently developing nuclear magnetic resonance instruments?

Professor Li Hongjun, the leader of the Infectious Disease Group of the Chinese Radiology Branch and the director of the Imaging Center and Radiology Department of Beijing You'an Hospital, stated in an interview with the People's Daily Health Client reporter that due to technological barriers, the key technical components of domestic nuclear magnetic resonance equipment in the past, such as magnets and radio frequency coils, were extremely difficult, especially the high field strength magnetic resonance system had higher technical requirements for magnets, shielding systems, and cooling systems, The technology is not yet perfect. For example, the signal acquisition technology of the coil is not up to standard, so it can only rely on imports, which is not only expensive but also takes a long time to book equipment. In recent years, there have been significant technological breakthroughs and improvements in the independent research and development of key magnetic resonance technologies such as RF coil production, magnet localization, and new sequence technology. In addition, the development of artificial intelligence has also driven the improvement of spatial and temporal resolution data processing, resulting in The processing speed and image resolution are both well utilized

For the research and development of domestic medical devices, solving the "bottleneck" technology problem is the first step, and in the future, stability and reliability will still need to be improved. In the past, we used to use imported nuclear magnetic resonance medical devices. Now, some of them have been replaced with domestically developed nuclear magnetic resonance machines, which can be comparable to foreign machines in daily use. However, in some high-end applications, we still have a certain gap. However, as doctors, seeing the continuous progress and rise of domestic medical devices, we are sincerely proud and proud The chief technician of the imaging department at a tertiary hospital in Dalian told reporters. (Wei Qiang, chief technician of the Imaging Department of the First Affiliated Hospital of Dalian Medical University, requested anonymity)

According to CCTV News, the latest generation of domestically produced nuclear magnetic resonance instruments have fully met the image quality requirements proposed by hospitals. And with the rapid imaging technology, even if the tissue moves, the photos will not "burn out" and the process of its movement can be seen.

Li Hongjun further analyzed that although there have been many breakthroughs and innovations in the key core technologies of domestic nuclear magnetic resonance equipment, there has also been a significant improvement in its performance. For a long time, medical institutions and technical personnel have a high level of trust in imported equipment. Therefore, to enhance their trust in domestic equipment, new policy support and a combination of industry, academia, and research are needed to further increase the research and development of key technologies, To improve the performance stability, reliability, and spatiotemporal resolution of the product.

With increasing government support and key technological innovation, achieving independent research and production of high-end magnetic resonance technology is just around the corner, which can greatly reduce medical costs and further improve the level of medical services, "said Li Hongjun.

After mass production, it will further promote the high-quality development speed of nuclear magnetic resonance instruments

Li Hongjun introduced that currently, due to the small scale of domestic enterprises in the supply chain of high field intensity magnetic resonance imaging system industry, the lack of unified standards for process technology and quality, some key components still need to be imported, making it difficult to form a high-quality market scale advantage, greatly increasing the difficulty of popularizing the domestic magnetic resonance market.

However, after mass production, it will greatly reduce medical costs and promote the high-quality development speed of national brands. In addition, during the use process, the quality and stability performance indicator system of the equipment will also be continuously improved

According to CCTV News, this self-developed nuclear magnetic resonance instrument has been applied in the Shenzhen Hospital of Peking University. It can also transmit the working condition of the instrument to the Chinese Academy of Sciences Shenzhen Advanced Technology Research Institute 15 kilometers away in real time for analysis.

What impact will the rise of domestic medical devices have on the future market? Hou Yan, Chairman of the China Medical Equipment Association, finally stated that the continuous progress of domestic technology has broken the monopoly pattern of imported medical devices and will definitely have a positive impact on the market. The original pattern was purely dependent on imports, and later domestic products emerged, but mainly focused on complete machine production. Now, many core components can be produced independently, so in the market pattern, locally produced products are gradually occupying the main position.
