Comprehensive Applications

High-definition diffusion imaging

DWI (Diffusion Weighted Imaging) is to show Brownian motion of water molecules by applying diffusion sensitive gradient on the basis of EPI (Echo Plane Imaging) sequence.

In OPENMARK 5000 system, we supply EPI (Echo Planar Imaging) with Single Shot and Multi Shot technology for high-definition diffusion weighted imaging. In one scanning, you can obtain 4 images of DWI: DWI images with high b-value, DWI images with 0 b-value, ADC-map, eADC-map.

In addition, LSDWI (Liner Shot Diffusion Weighted Imaging) can also provide a high b-value DWI images in low filed MRI system.

DWI is a necessary function for the examination cerebral infarction, brain tumor, malignant lesions (body) and bone tumor, etc.

High-resolution angiography imaging

 TOF (Time-of-Flight) 2D/3D is based on the enhancement effect of blood flow, and is mainly used for the examination of cerebral blood vessels, neck blood vessels, and lower limb blood vessels. The newly optimized sequence and parameters can control the MRA scanning time to about 5 minutes or even less in low field MRI, while improving the image resolution.

MTC (Magnetization Transfer Contrast) technology and TONE (Tilted Optimized Non-saturation Excitation) pulse to improved Contrast to Noise Ratio of images.

Fast recovery technology

For the traditional T2WI based on FSE sequence, we always need set a long TR (Time of Repetition) to avoid the introduction of T1 relaxation signals, and get a good T2 weighted image. However, in daily scanning, due to the limitation of scanning time and hardware performance, it is always difficult to get good contrast T2 weighted image.

In the new imaging platform, we have introduced fast recovery technology and optimized the traditional FSE sequence, which can greatly shorten the TR time, while eliminating the T1 relaxation signal, providing better T2-weighted imaging, and the scanning time is also significantly shortened, can provide better image quality in nerves, abdomen and other parts.

K-space data share technology

In traditional MRI scans, the patients are always required to stay still, to avoid image artifacts, but it’s still unavoidable for breathing, heartbeat, pulse, etc., Especially for abdominal scanning, low- field MRI is difficult to obtain an ideal image even if it is scanned in a gated trigger mode due to the long scanning time and difficult patient cooperation.

K-space data share technology is a new technology that can share the K-space data between each slice in a scanning, in this way, the K-space data that needs to be collected will be reduced, so the scan time will be greatly shortened. For example, for a whole liver T1-GRE scanning, total scan time is less than 15s, can be finish in a single breath-holding for most patient, which also provide a good contrast image without any breath artifact.

PROP data filling technology

PROP (Periodically Rotated Overlapping Parallel) data filling technology is another method of MRI data collection and reconstruction, which will reduce the motion artifact of images without information loss, to greatly improve the scan success rate of restless patients.

Advanced Dixon imaging

DIXON (Water and Fat Separation) technology, based on the chemical shift effect, by adjusting different echo times, to obtain T1-weighted image, water image, fat image, in-phase image, and out of-phase images in one scanning. The combined application of the two-point method and the three- point method can guarantee the success rate of scanning each part.

AI technology for MRI imaging

With the development of computer technology, Artificial Intelligence (AI) technology has been more and more widely used in some high-tech fields. Especially in the field of medical imaging, AI technology is also increasingly used in process optimization, image processing, and auxiliary diagnosis, etc. which can greatly improve work efficiency and reduce the workload of medical workers. As one of the top leading high-tech medical imaging manufacturers, ANKE has always been committed to the research on the application of AI technology in MRI.

AI-Auto Localization technology

 AI-Auto Localization technology uses AI to separate the tissues of the vertebral body, then find the corresponding intervertebral disc based on the vertebral body and place the cross- sectional positioning line parallel to the long axis of the intervertebral disc and perpendicular to the sagittal plane of the spine. This can greatly reduce the complexity of the operation, also, it can save time and avoid position and angle errors caused by manual operation.

AI-Image Enhancement

Compact design

Integrated patient table

Integrated patient table, ultra-wide table and suspension design, will ensure the comfort of patients and operators while saving space.  Touched LCD screen and automatic positioning function, will improve your working efficiency.

Integrated cabinet

Newly designed integrated electronic cabinet, integrated with Isolated power module and automatic air-cooling system, will greatly improves the space utilization. One-key ON/OFF switch function further simplifies daily operations.
