From learning to innovation The magnificent chapter of Xin Gao Yi's development



In May 2019, the world's first 1.5T liquid helium-free superconducting magnet for whole-body imaging was innovatively developed by Xingaoyi-Ningbo Gaosi Superconducting Technology Co. This cryogen-free superconducting magnet technology breaks through the dependence on liquid helium, overturns the traditional design thinking, and creates a new situation in the medical imaging industry.


Helium is found in very small amounts in nature and has important uses in satellite spacecraft launches, the missile weapons industry, low-temperature superconductivity research, and semiconductor production. More than 80% of the world's liquid helium supply comes from the U.S. Since 2007, the U.S. has restricted helium production by designating helium as a strategic resource, which has led to a continuous spike in global liquid helium prices. China has only 0.2% of the world's helium resources, while the U.S. has more than 50%.
 
How to reduce the use of liquid helium and reduce the dependence on liquid helium is a new challenge that manufacturers have to face in the future. Xingaoyi's cryogen-free superconducting magnets completely get rid of the dependence on liquid helium and truly open a new era of liquid helium-free superconducting magnetic resonance.

The development of superconducting magnet technology from 10K (less volatile magnets) - 4K (zero volatile magnets) - low liquid helium (Philips operating technology Freelium) - no liquid helium (Xingaoyi cryogen-free superconducting magnets). This perfect innovation process is realized on our glorious Chinese soil! Let's raise a glass and celebrate!


Xingaoyi's cryogen-free superconducting magnets are 100% liquid helium-free with direct conduction cooling by a cryocooler. Compared with other manufacturers' low liquid helium technology, our magnets are completely free of liquid helium and therefore have a series of advantages as follows.
1. Easy to use and not limited by geographical location
2. Low manufacturing and maintenance costs
3. Small size, light weight and low site requirements  
4. Easy to install, no emergency helium outlet required
5、Simple operation and maintenance, high safety
6、It can be rotated 360°.


The main performance specs. of Xingaoyi cryogen-free superconducting magnets are comparable with mainstream products, especially in terms of weight and cost.

The world's first, made in China. The cryogen-free technology will definitely overturn the traditional magnetic resonance industry, change the international superconducting technology industry ecology, lead the technical change of superconducting magnetic resonance system, open up a new era of magnetic resonance technology, and generate huge social and economic benefits.
