3.0T MRI Superconducting Magnet

Scope of Application：

The 3.0T superconducting magnet for MRI systems designed and developed by our company achieves a magnetic field strength of 3.0T, with a magnetic field uniformity of <2ppm (vrms) within a 45cm spherical volume, a magnetic field stability of <0.05ppm/h, and zero liquid helium evaporation. This provides core component support and essential conditions for developing 3.0T MRI systems that enable new imaging technologies in the field of precision medicine.

Due to its advantages in signal-to-noise ratio, resolution, and scan time, high-field MRI not only shortens patient examination time but also enables research in spectroscopy and functional imaging, making it the new mainstream in the current market. It serves as an advanced dual platform for both clinical and scientific research, representing the fastest-growing segment in the future MRI market.

Technical Features

◆ With a magnetic field strength of up to 3.0T, the imaging system holds a clear advantage over 1.5T in terms of signal-to-noise ratio, resolution, and scanning speed. Additionally, it enables research in spectroscopy, molecular imaging, and functional imaging, making it an advanced dual platform for both clinical and scientific applications.

◆ Zero Helium Evaporation: Based on the 1.5T MRI magnet, the cryogenic system design has been optimized to achieve complete zero evaporation for the 3.0T magnet, significantly reducing operating costs and maintenance expenses.

◆ High magnetic field uniformity: After passive shimming, the uniformity within a 45 cm spherical region can reach <2 ppm (vrms), meeting the requirements for high-quality imaging.

◆High Magnetic Field Stability: Inheriting the advanced manufacturing process of 1.5T superconducting joints, the magnetic field stability is reliably ensured, extending the effective magnetic field retention time, reducing maintenance costs and frequency, and guaranteeing imaging clarity, consistency, and reproducibility.

◆The magnet monitoring module is fully functional: it effectively monitors operational data such as the magnet's 4K pressure and liquid level, ensuring the safe operation of the magnet.

◆ Advanced Low-Temperature System Design: The highly efficient low-temperature system reduces the power requirements of the cold head for the magnet, significantly extending the cold head's service life.

◆5G's small coverage range: It can effectively avoid signal interference from the external environment.
