August 18, by the Weifang Sony Superconducting Magnetic Technology Co., Ltd. independent research and development of the world's first 3.0T / 850 nuclear magnetic resonance molecular imaging superconducting magnet prototype success. The authoritative expert inspection group composed of academician Ye Zhaohui of the Chinese Academy of Sciences said that all the indexes of this magnet are satisfied with the requirements of high-quality imaging of the 3.0T NMR system and reached the international advanced level, which is of great practical significance in clinical application and medical research . Its advent not only broke the long-term monopoly of foreign technology, but also marked the development of China's high-end medical imaging equipment has been in the forefront of the world.
Nuclear Magnetic Resonance Molecular Imaging Superconducting magnets are the core components of a nuclear magnetic resonance system. Their magnetic field strength, stability and uniformity affect the image formed by the system greatly. Type 850 superconducting magnet is designed for Asian body. Its aperture is 850mm at room temperature. The magnet weight is 6000kg. The liquid helium capacity is 1000L. The center field strength is 3.0 ± 0.015T (Tesla). The magnetic field uniformity is less than or equal to 10ppm. It is one of the most advanced high-end medical imaging equipment in the world that can perform high-quality scanning of various parts of the body on the MRI system. Compared with the traditional 1.5T nuclear magnetic resonance system, it has obvious technical advantages of high imaging speed, high image quality and small scanning noise, so that patients can get the quickest and most accurate diagnosis and win valuable opportunity for the effective treatment of the disease.
According to the National Magnetics and Cryogenic Superconducting Magnets Industry Technology Innovation Strategic Alliance chairman, Weifang Sony Superconducting Magnetics Technology Co., Ltd., chairman of Wang Zhaolian introduction, the magnet design of the advanced cryogenic system can be achieved zero volatilization of liquid helium, greatly reduced Equipment costs and maintenance costs. At the same time, the magnet has also designed the monitoring module function, which can effectively monitor the operation data of the magnet 4K pressure and liquid level to ensure the safe operation of the magnet.
The successful development of the world's first 3.0T / 850 nuclear magnetic resonance molecular imaging superconducting magnet prototype is a microcosm of the rapid development of China's high-end medical imaging equipment, marking the development of China's high-end medical imaging equipment to a new level!
