BSTAR-070 open type superconducting MRI 0.7T good image quality
less consumption dual column strong gradient
Evolution Compared To Conventional Permanent Magnet MRI:
In the magnet structure, Bstar-070 uses liquid helium get the
superconductive environment, and equipped by multiple Helmholtz
superconducting coil charging with current to generate the magnetic
field, the magnetic field strength is 0.7T.
The Helmholtz coil is made of a number of same radius coil, the
coils are coaxial concatenated placed. The coil array can generate
up to dozens tesla's magnetic field.
Special Characteristic of This Product:
A, very large open space;
B, very good magnet stability without the interference of magnet
temperature.
C, very good magnet field homogeneity.
D, Liquid helium only 120L, much better than any 1.5T MRI system.
E, 46cm magnet gap, even better than permanent MRI system.
F, perfectly support the MRI intervention operations.
Rich coil configuration
The Receiver coil, together with parallel acquisition technology,
improve the signal-to-noise ratio and image quality. The customer
can choose according to the clinical needs (specific configuration
of the coil number and types will be subject to final contract).
head coil
neck coil
body coil(s)
body coil(soft)
knee coil
breast coil

E-alarm technology
At the same time, in Bstar-070 configuration there is a special
monitoring system, it is simple and easy to operate, it can
real-time monitoring the magnet internal pressure, temperature and
liquid helium level, if the magnet condition is abnormal, the
monitoring system can automatically send alarm information to the
user's phone, it can greatly reduce the risk of magnet quenches.
Interactive systems
Bstar-070 provide comprehensive scan kit and scanning sequence,
with rich clinical application of the full body, with a full range
of scan plan, assist the customer’s clinical diagnosis. Advanced
scanning sequence are provided as well as all routine scan, the
system also can take vascular imaging, MRU/MRCP/MRM imaging, DWI
imaging and other advanced imaging sequences. Rich post-processing
software can optimize images in case necessary to help in complex
diseases diagnosis.
