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.
