The magnetic field uniformity of superconducting magnets has reached the international first-class level, with a background magnetic field of 3.0T and a spherical uniform field value of less than 5ppm for 16CM.
The escape scene is small. Adopting a self shielded superconducting magnet design, the magnetic field 5Gs is less than 3m, which is 2/3 to 1/2 of the traditional 3T full body type, saving installation space and floor space.
(1) 3.0T ultra-high field
(2) Magnetic field uniformity < 5ppm (P-P)
(3) Magnetic field stability < 0.05ppm/h
(4) Restricted dimensions with inner diameter ≥ 300mm and length ≤ 620mm
(5) Low liquid helium, zero volatilization

High gradient strength and high switching rate. High performance gradient system design, with gradient field strength and switching rate 2 to 3 times higher than traditional 3T whole-body magnetic resonance imaging. Higher b-values can be applied for diffusion-weighted images to improve contrast; At the same time, it can also perform high-resolution imaging and 3D imaging at the micrometer level.
(1) High gradient field strength of 110mT/m
(2) Super climbing rate of 700T/m/s
(3) 170mmDSV, > 2% nonlinearity
(4) > 1% eddy current (eddy current suppression technology)
(5) Can achieve active homogenization

Low RF power and small SAR absorption effect. The RF power is 1/5 of the traditional 3T whole-body type, and the optimized RF coil design eliminates SAR hotspots, making scanning safer. At the same time, sequences with high excitation pulses such as FSE can be scanned normally without entering controlled mode.

(1) Small aperture, large effective volume, uniformity of all RF coils ≥ 90%
(2) High signal-to-noise ratio
