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-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.
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-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.
Rich Coil Configuration
The Receiver coil, together with parallel acquisition technology, improve the signal-to-noise ratio and image quality. The customer can choose according to the clinical needs (specific configuration of the coil number and types will be subject to final contract).
  • AIT coil set

    Bstar-150 provides the power, coils and sequences for fast, intuitive, high quality spine imaging, from routine views to advanced stitching studies.

    K_Rotat artifact erasing technique, by using stripped K space rotating filling method to complete acquisition, can completely erase the effect of movement artifact on images and greatly improve SNR at the same time to provide guarantee for accurate diagnosis.

    Bstar-150 provides a versatile suite of imaging capabilities for body imaging to meet the growing demands of abdominal, pelvic, and breast exams. Including MRU/MRCP/MRM imaging, and other advanced imaging sequences. Rich post-processing software can optimize images in case necessary to help in complex diseases diagnosis, excellent image quality and abundant imaging techniques.

    Workflow is critical to the efficient operation of an MRI. It impacts patient satisfaction, image quality and cost effectiveness. Bstar-150 provides full preset of clinical diagnostic scan protocol, based on rich clinical experience, corresponding arrangement and optimization have been made per related clinical application features for the scan procedure and sequence parameters of the preset scan method. With unmatched clinical capability, Bstar-150 provides an unprecedented ability to acquire complete exams with a motion compensated scan technique.

    For restless patients and those who can’t cooperate, the preset extremely fast scan sequence can be used, which is very appropriate for fetus, newborns and infants.

    High resolution isotropic diffusion imaging, based on powerful gradient system and amplifier system, Bstar-150 realizes faster and more reliable DWI images with high resolution, anatomic structure of head is clear, diffusion image features is obvious, very convenient for lesion location lock and lesion nature diagnosis.

    HD susceptibility-weighted imaging, imaging based on the differences of magnetic susceptibility in different tissues, is a contrast enhancement technique which reflects magnetic properties of tissue. It is extremely sensitive to bleeding or deoxidation part in blood, can provide accurate information on bleeding, arteriovenous malformation, iron deposit to realize faster and more accurate diagnosis, even the very small lesion can be quickly diagnosed too.

    Fast high-resolution abdomen diffusion imaging, under the support of brand-new parallel acquisition technique, realizes abdomen diffusion imaging with high spatial resolution, high time resolution and high contrast resolution, providing excellent tool of abdomen cancer diagnosis.

    Extremely HD 3D TOF blood vessel imaging, optimized K space acquisition and filling method, suppression uniform of obtained images background, no artifact, clear blood vessel trend, can display tertiary vascular or above.


    scDWI (optional)

    In DWI, acquisition of low-b-value has better tissue SNR, but is not sensitive enough to water proton;

    Acquisition of high-b-value has better DW sensitivity of water proton, but reduces the tissue SNR as well as the lesion location function;

    By using special computation method, scDWI only needs one single DWI sequence to complete the calculation of multi-b-value within certain range, min. 100s/mm².

    Meanwhile, comparing to direct acquisition of DWI images, scDWI technique greatly improved the SNR of high-b-value DW image, avoid distortion of high-b-value images, very good for lesion diagnosis.
