· Magnet Strength: 0.5T(Upper) / 0.35T


· Classic
 Vet MRI combined many pioneering MRI imaging technology and human-based humanized design concept, making it achieve high.  Vet MRI led a technical revolution in the permanent MRI field. It provides clear images and stable system quality, the system is used for rabbits, cats, monkeys, dogs, it can make an accurate diagnosis of pet animal diseases with a reliable basis, in order to facilitate the veterinarian hospitals in the diagnosis and treatment. The system is applicable to the laboratory, pet hospital, etc.

Vet 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, a breakthrough in the industry field and achieved:

· Eddy Zero Technology
Make sure the imaging quality achieved qualitative improvement.
The shimming algorithm technology (ensure field strength with high uniformity and stability), ensure the MRI system operates 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.  Vet MRI system not only breakthrough the bottleneck historically, and achieved the “high stability, high performance, high imaging quality and high efficiency”. And with the specially designed high power gradient magnet field for Vet MRI, it achieved as an all-new concept Vet MRI system. 

· Much Open, Easy for The Operator
More space for surgery. Affinity C-shape magnets, creating a maximum of openness, offer a maximum vision for doctors, especially leaving much space for operation.


· High-performance Gradient System
Gradient system helps to provide higher resolution pictures,  Vet MRI’s gradient system（X、Y、Z） gradient intensity is 15mT/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 maintains 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.

Eddy Zero Technology:
a)Magnet design uses breakthrough anti-eddy current technology

b)The gradient coil using self-shielded active anti-eddy current technology
c)Implementation of precision eddy current compensation algorithm, completely eliminate the impact of eddy current
The eddy current together with the high gradient and high slew rate coming from the ultra-fast sequence was resolved completely, guaranteeing to get the best clinic image.

· Advanced RF System
Fast 2 channels RF system. All phased array coils provide the best SNR pictures.
