This is the first helium liquid free MRI developped in China. Recently, Basda has announced the launch of the helium-free 1.5T superconducting MR that helps solve the problem of global liquid helium shortage. Generally, a conventional 1.5T superconducting MRI requires nearly 1,000 Liter of liquid helium to operate normally. Our product hence becomes China's first MR system to enable helium-free operations, reducing the chance of potentially lengthy, costly, and even deadly disruptions, and virtually eliminating the dependency on a commodity with an unpredictable supply.

1) There is no liquid helium in the machine meaning there is no liquid helium loss under any circumstances.
2) There is no risk of frostbite or suffocation for doctors and patients.
3) The system is equipped with the functions of automatically dropping the field when the power is cut off, and automatically raising the field when the power is restored.
4) Using cloud interconnection technology, the status of the magnet can be viewed remotely through a mobile phone, and the system can be remotely operated such as lifting and lowering the field.
5) It can be installed in any country and region, completely isolated from the influence of liquid helium supply;
6) There is no need to configure a quench tube like the traditional 1.5T superconducting MRI, which protects the safety of patients and surrounding residents to the greatest extent.
7) Lower service tower height makes site selection easier;
8) Available with shipping, air transportation and land transportation which greatly minimizes the difficulty of magnet transportation;
9) The new magnet architecture platform adopts modular design with higher integration. After quenching under blackout, the magnet field can be automatically restored in a short period of time without the need for professional engineers to arrive on site.
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-150 suing 8 / 16 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.
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-150 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 than permanent MRI systems, and staying in a closed environment, the patient is easy to fall into tension. Bstar-150’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 use water chiller to produce a stable running condition.

Have you heard of the liquid helium crisis?
Unfortunately, liquid helium, which is not only used in MRI machines but also in research, aviation, rocketry, weather balloons, and more, is one of the rarest elements on Earth. And in retrospect, a lot of the finite Helium reserve was wasted by selling it at a very low price.
Currently, more than 80% of the world's liquid helium supply comes from the United States, and China only accounts for about 0.2%. As a scarce strategic resource, liquid helium is very expensive. China’s liquid helium has long been dependent on imports from the United States, Qatar and other regions. Over the years, liquid helium became less available and the lack of helium supplies in the world increases the prices of liquid helium and worries people in the medical industry. Starting from 2019, global liquid helium production capacity will continue to decline for 3 consecutive years. In 2021, global annual production will drop to 2/3 of 2019. Therefore, the global liquid helium shortage is one of the urgent problems to be solved in the foreseeable future.
In response to the problem of liquid helium shortage, Basda Medical has made great efforts in R&D, adopting the breakthrough Green-Cool ultra-low temperature transmission technology that does not require liquid helium, and successfully develops a 1.5T superconducting MRI with literally "no liquid helium", in other words "zero consumption" MR system.
Basda come to the market since 2000, got great improvement in service, gradually establish a set of mature service strategy, including
