BTI-050 permanent MRI system, not only had accumulated the products’ technical essence from major companies home and abroad, but also followed the developing trend, and with constant innovation, breakthrough in the industry field and achieved:
Eddy zero technology
Make sure the imaging quality achieved qualitative improve.
The shimming algorithm technology (ensure field strength with high uniformity and stability), ensure the MRI system operating stably with high quality and high performance.
The high magnetic uniformity, high stability, fast and accurate position operation are always the hard breakthrough technical bottleneck. BTI-050 permanent MRI system not only breakthrough the bottleneck historically, and achieved the “high stability, high performance, high imaging quality and high efficiency”. And with the special designed high power gradient magnet field for BTI-050, it achieved as an all-new concept permanent MRI system.
Much open and comfort
More patient comfort and more space for surgery. Affinity C-shape magnets, creating a maximum of openness, offer a maximum vision for patients, especially leave much space comfort for obese patients, minimizing claustrophobia of patients and providing more space for MR intervention surgery.
Very good gradient system
Gradient system helps to provide higher resolution pictures, BTI-050 gradient system(X,Y,Z) gradient intensity is 25mT/m,Higher the gradient intensity, faster imaging speed, shorter of scanning time; Higher the gradient intensity, thinner of imaging slice, higher of image resolution.
The new technology
4D shimming:
Use of advanced active shimming algorithm for real-time automatic shimming on each examination to ensure the magnetic field always maintain the highest uniformity. Magnetic field homogeneity and stability of the MRI images always are the most important guarantee of the high-resolution, high SNR and high contrast. They are the important indicators of the level of magnet design, the better the smaller the value, directly determines the SNR of the image, like a car chassis, stability is essential, the magnetic field uniformity is maintained at <2.5ppm in 40cm the DSV Vrms, the system can complete a wide range of scanning (40cm).
Eddy Zero Technology:
- Magnet design uses breakthrough anti-eddy current technology
- The gradient coil using self-shielded active anti - eddy current technology
- Implementation of precision eddy current compensation algorithm, completely eliminate the impact of eddy current
- The eddy current because of the high gradient and high slew rate come from ultra-fast sequence was resolved completely, which guarantee to get the best clinic image
