BSTAR-070 open type superconducting MRI 0.7T good image quality
less consumption dual column strong gradient and RF shim
FAST DESCRIPTION
Bstar-070 superconductive magnetic resonance imaging system is the
world’s first open type superconductive MRI product, the system has
both superconductive magnetic resonance system’s advantage of fast
scanning speed, high image signal-to-noise ratio features, and
permanent magnet magnetic resonance system’s advantage of low
operating cost, patient comfort. It satisfies all the customer
demand for a magnetic resonance system.
Gradient sub system
Gradient sub system directly determine the spatial encoding of MRI
system, it produces the signal information, at the same time it can
perform GR series sequence scanning, it is the foundation of MRI
system’s spatial resolution ability, gradient sub system also
directly affect the scanning image thin slice scanning.
The linearity of gradient system of MRI system determine the
accuracy of spatial location information, ensuring that in any
acquisition, the image distortion is limited.
Gradient switching rate is an important factor of MRI scanning
speed. Bstar-070 using the self-shielding gradient coil and high
duty cycle gradient amplifier system, together with eddy zero
technology and design, not only can avoid the eddy current between
the metal shielding layers, but also can concentrate the eddy
current from X axis and Y axis to Z axis, then by software
algorithm, eliminate all eddy current. This technology can raise up
the spatial encoding ability of the magnetic resonance signal and
make the scan more precise, ensure high resolution image quality
When gradient system working its current is high, and switching
rate is high as well, thus the noise emitted by MRI system is easy
to make the patient discomfort, Bstar-070 using special hardware
noise reduction design technology, the original gradient noise is
reduced up to 66%, and Bstar-070 provides a friendlier scanning
environment for the patients.
The gradient system using air cooling to save maintenance cost for
the user.
RF sub system
The RF sub system is the source of MRI proton excitation energy,
its efficiency directly affects the MRI relax signal. RF receiver
receive MRI relax signal, a good receiving coil can improve the SNR
of image.
The RF sub system is similar as highway lane, the more lanes, the
faster flow of vehicles. Vice versa, the more the RF system
channels, the faster parallel acquisition, thus the system can
process the greater the amount of data in the same time, reduce the
imaging time. Bstar-070 suing 4 channel radio frequency receiving,
combined with the latest parallel sampling technology, using the
DDC digital direct sampling, can short the scan time and get
excellent image quality.
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.
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.
