Anti Electromagnetic Superconducting MRI Phase Array Coils BSTAR-300 816 Channel

Gradient sub system

Gradient sub system directly determines 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-300 using the self-shielding gradient coil and high duty cycle gradient amplifier system, together with eddy elimination technology and design, can avoid the eddy current between the metal shielding layers, raise up the spatial encoding ability of the magnetic resonance signal and make the scan more precise, ensure high resolution image quality.

During superconducting MRI scans, the noise is much bigger, and staying in a closed environment, the patient is easy to fall into tension. Bstar-300’s gradient sub system adopts special hardware noise reduction design technology, the gradient noise is reduced to 2/3, provide patients with friendly scanning environment.

The gradient system is equipped with automatic detection function, if the temperature is too high, the system can intelligently stop the scanning, to protection of hardware from being damaged.

The system uses water chiller to produce a stable running condition.

Magnet sub system

• Bstar-300 adapts advanced active shielding superconducting magnet, has the following features,
• the magnetic field uniformity is excellent;
• good magnetic field stability;
• config with “zero liquid helium consumption” technology, the liquid helium refill time interval is more than 4 years

Water chiller set

Intelligent touch screen design, visual operation, and be convenient for maintenance.

1. automatic overheating, leaking, fault detection, safe and reliable.
2. one key recovery function.
3. config with a set of spare water chilling unit, no need to have any worry about the system downtime.

E-alarm technology

At the same time, in Bstar-300 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.

RF sub system

1. The source of MRI proton excitation energy, its efficiency directly affects the MRI relax signal.
2. RF receiver receive MRI relax signal, a good receiving coil can improve the SNR of image.
3. 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.
4. Bstar-300 uses 16/32 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.
