The 9.4T MRI system is one of the most powerful imaging devices in the world, with only four in the world. In the scenic Yanhuan Lake of Yanqiu, the research building of the Yanqi Lake Campus of the Chinese Academy of Sciences, there is a 9.4T MRI system independently developed by the Chinese Academy of Sciences.
According to experts from the Institute of Biophysics of the Chinese Academy of Sciences (hereinafter referred to as the Institute of Biophysics of the Chinese Academy of Sciences), the nuclear magnetic resonance used in our commonly used hospitals is hydrogen nuclear magnetic resonance, and 9.4T can not only produce higher resolution hydrogen. Nuclear resonance imaging is also capable of imaging sodium and phosphorous nuclei. Since phosphorus and sodium are extremely small in the nucleus, a high signal-to-noise ratio is required to amplify their signals, and a higher magnetic field provides a higher signal-to-noise ratio and resolution. Hydrogen nuclear resonance images can only see the structure and cannot provide more information about metabolic processes. Both sodium and phosphorus are related to metabolism. Therefore, nuclear resonance imaging of sodium and phosphorus can be used to study the metabolic processes of the human body, and to help study basic life science problems such as brain and cognition, as well as tumor and neurological diseases. And other medical problems.
In the 9.4T MRI system, the Institute of Biophysics of the Chinese Academy of Sciences is mainly based on application-level research and system construction, and has achieved breakthroughs in local technology, such as solving the problem of superconducting magnets reaching a uniformity of 9T or more. This is only one or two companies in the world can do it.
In the future, with the deepening of life science and medical research, the 9.4T MRI system will be more valuable in medicine. For example, the 9.4T MRI system is more clear and finer than the 3T currently used in clinical medicine , and can clearly display fine-grained images. In the diagnosis of certain diseases, when the 3T system cannot be clearly observed, the specific application value of the 9.4T system can be reflected at this time.
However, relevant experts also said that the current stage of 9.4T is still mainly used for scientific research, and its application value depends on further research results and market demand. Doctors mainly observe pathological structures, but scientists will conduct more subtle and deeper research, such as changes in microstructure and their effects when people are thinking.
Professional computer room construction: University questions outside the parameters
At the same time as the development of the 9.4T MRI system, the construction of the supporting professional computer room is a huge challenge for the project team. According to the person in charge of the project, the larger the magnetic field of the instrument, the higher the corresponding signal-to-noise ratio. The magnetic field strength of the familiar MRI is only about 1.5T. Today, the Chinese Academy of Sciences is facing a 9.4T ultra-high-intensity magnetic field. The magnetic field is affected by the outside world and also affects the outside world. A moving car may also cause data deviation caused by disturbance of the magnetic field.
In order to solve the problem of super-strong magnetic field, the Chinese Academy of Sciences needs to build a special machine room with an area of ​​several hundred square meters. This machine room seems simple, but it is a typical "high-precision" project.
In addition to the need to solve the installation of professional isolation equipment for ultra-strong magnetic fields, the project team should also consider how to ensure the deployment and maintenance of power supply, cooling and related equipment in the equipment room. To this end, the Institute of China has carried out public bidding for the infrastructure of the computer room including UPS, air conditioners and water machines, and set high standards for the reliability, energy efficiency and flexibility of the supporting products.
Among them, UPS as a protective power supply device is the core component of the construction machine room. Although its performance parameters have important reference significance, modern equipment rooms must be constructed to consider whether they have the ability to deploy new architectures, whether they can meet the requirements of green power storage, and whether they are scalable to meet the needs. Growing application needs.
At the same time, the precision air conditioning water system is a relatively complex system, which is crucial for the operation of the precision air conditioning system in the engine room. Similarly, under the general trend of emphasizing green environmental protection, if the construction equipment room cannot provide effective power supply and cooling solutions, the inefficiency of the equipment room will be particularly prominent.
To solve the above problems, we must start from the infrastructure of the computer room. This is a professional computer room with a university question.
Reliable protection comes from: practical experience + industry reputation
For the selection of this partner, the Institute of Science and Technology not only proposed that the equipment should be matched with the 9.4T MRI system, and it is resistant to strong magnetic interference and high-quality brands. It is more clear that it must have all-digital technology, provide network management system and be accompanied by monitoring. Software, and can provide technical training program services, as well as free warranty for service providers equipment for not less than three years, maintenance and maintenance during the warranty period of not less than once; after receiving equipment failure report, response time should be within 30 minutes; Solve problems and many other stringent standards in the field within 6 hours.
This means that the level of service specialization and response speed of the supplier must meet the requirements. The Chinese Academy of Sciences requires the use of a unified brand, which is the guarantee of future unified operation and maintenance and after-sales service.
After rigorous screening and in-depth investigation, the Institute of Biophysics of the Chinese Academy of Sciences finally selected Schneider Electric Solutions Advanced Certification Partner, which has deep accumulation and leading solutions in data centers and other IT critical environmental fields - Beijing Yafang Like Technology Co., Ltd. Fang Like has a rich application practice in the nuclear magnetic industry. It not only provides Schneider Electric air-conditioning and water machine solutions for the first high-end PET/MR and cyclotron engine room in the Midwest, but also the world's largest one-of-a-kind international proton.

This cooperation, the Chinese Academy of Sciences is most valued is the high-quality products, practical experience and industry reputation of Yafang Likeo in the field of nuclear magnetic equipment. After repeated investigations and demonstrations at the Institute's site, and considering that Schneider Electric's power distribution and cooling solutions have always been the primary choice for industry users in extreme and demanding applications. Yafanglik has designed the computer room infrastructure for the Chinese Academy of Sciences: unified use of Schneider Electric's UPS, chillers, air conditioning and other related equipment, including Schneider Electric Galaxy 7000 UPS, Youli Aquaflair refrigeration system, and Leonardo precision air conditioner All supporting power supply and cooling solutions within the 9.4T MRI system ensure reliable, efficient and green operation.

Excellent computer room security is to ensure our research 9 The important foundation for the success of the .4T MRI system!"
Yellow rice wine is a type of Chinese rice wine made from glutinous rice, wheat, and water. It is commonly used in Chinese cooking and is also consumed as a beverage. Shengta wine is traditionally made by fermenting the rice in a clay jar with a starter culture of yeast and koji (a type of mold). The fermentation process can take several months, and the resulting wine is typically clear with a yellowish tint. Yellow rice wine has a mild, sweet taste and is often used in marinades, sauces, and soups to add flavor and depth. It is also believed to have health benefits, such as aiding digestion and promoting blood circulation.
