Specifications

Product Details

1. 75 cm Ultra-Wide Bore

The defining feature of the uMR Omega is its 75 cm ultra-wide bore, which is significantly wider than the conventional 60–70 cm MRI bore.

United Imaging describes the uMR Omega as the world's first ultra-wide-bore 3T MRI system with a 75 cm aperture. Compared with a 70 cm bore, the larger aperture provides approximately 15% more patient space.

The wider opening can improve accessibility for:

· Obese patients

· Elderly patients

· Patients with limited mobility

· Patients who are uncomfortable in confined spaces

· Patients requiring special positioning

· Patients undergoing large-area or whole-body imaging

The wide bore also opens up possibilities for specialized applications such as radiotherapy MRI simulation and potentially intraoperative MRI.

2. High Patient Weight Capacity

The uMR Omega supports patients weighing up to 310 kg (681 lbs).

The patient table measures:

· 262 cm in length

· 64 cm in width

· 88 cm in height

This combination of a wide bore and high table load capacity is designed to expand MRI accessibility for larger patients.

The system also supports a maximum FOV of 60 × 60 × 50 cm³, providing flexibility for large-area imaging.

3. High-Performance Gradient System

Despite its ultra-wide bore, the uMR Omega maintains high gradient performance.

The system provides:

45 mT/m maximum gradient amplitude

and

200 T/m/s maximum slew rate

These specifications provide the gradient performance required for advanced diffusion imaging, high-resolution anatomical imaging and accelerated MRI applications.

The high-performance gradient system is particularly useful for:

· DTI

· DWI

· High-resolution 3D imaging

· Vascular imaging

· Neurological MRI

· Fast orthopedic MRI

· Whole-body MRI

4. High Field Homogeneity

The uMR Omega combines its 75 cm bore with a highly homogeneous 3.0T magnetic field.

United Imaging lists a typical field homogeneity of:

0.029 ppm @ 30 cm DSV

The high homogeneity is particularly important for wide-FOV imaging because variations in the magnetic field can negatively affect image uniformity and fat suppression.

The system is designed to provide consistent image quality across a large field of view and support skin-to-skin fat saturation for wide-field imaging.

5. uAIFI AI Imaging Platform

The uMR Omega is built around the uAIFI Technology Platform, which integrates AI throughout the MRI imaging chain.

The platform combines AI technologies for:

· Data acquisition

· Image reconstruction

· Patient sensing

· Scan acceleration

· Workflow automation

· Post-processing

Two of the most important technologies are ACS and DeepRecon.

United Imaging describes this combination as a Dual AI Engine, with ACS operating during acquisition and DeepRecon enhancing reconstruction.

6. ACS AI-Assisted Compressed Sensing

ACS (AI-assisted Compressed Sensing) is United Imaging's AI-powered MRI acceleration technology.

It combines multiple acceleration approaches, including:

· Compressed Sensing (CS)

· High-frequency information

· Parallel Imaging (PI)

· Deep learning

The objective is to balance scan speed and image quality.

According to United Imaging, ACS can allow users to:

· Improve image quality without significantly increasing scan time

· Reduce scan time while maintaining image quality

· Acquire higher-resolution images within shorter examinations

· Reduce motion artifacts

· Increase patient throughput

The official page also describes body-part acquisitions within approximately 100 seconds under specified conditions. Actual scan time varies by protocol and examination.

7. DeepRecon AI Reconstruction

DeepRecon is the AI reconstruction component of the uAIFI platform.

It is designed to improve image quality by using deep learning during image reconstruction.

When combined with ACS, the system creates an AI-powered imaging chain extending from acquisition to reconstruction.

This can help achieve:

· Higher image quality

· Improved image sharpness

· Better visualization of small anatomical structures

· Shorter scanning times

· Reduced motion artifacts

United Imaging specifically highlights ACS + DeepRecon for rapid brain imaging, high-resolution 3D imaging and accelerated whole-spine examinations.

8. EasySense Contactless Respiratory Sensing

EasySense is a contactless respiratory monitoring technology based on a dual-source millimeter-wave radar system.

Unlike traditional respiratory belts, EasySense does not require a belt to be attached to the patient.

It can monitor respiratory movement during MRI examinations and support respiratory-gated imaging.

This is particularly useful for:

· Abdominal MRI

· Free-breathing imaging

· Pediatric examinations

· Elderly patients

· Patients who have difficulty holding their breath

The uMR Omega uses EasySense to support high-resolution abdominal MRI without breath-holding.

9. QScan Quiet MRI

MRI examinations can produce significant acoustic noise, particularly during gradient-intensive sequences.

The uMR Omega incorporates QScan, a quiet scanning technology designed to suppress acoustic noise at its source.

United Imaging reports background noise of around 60 dBA on its uMR systems, while the actual noise-reduction percentage depends on the examination and usage conditions.

The quieter scanning environment can improve patient comfort and is particularly beneficial for:

· Pediatric patients

· Elderly patients

· Claustrophobic patients

· Patients requiring long examinations

· Patients undergoing repeated MRI scans

10. SuperFlex Coils

The uMR Omega uses the SuperFlex Coil family of RF coils.

Unlike rigid conventional coils, SuperFlex coils are designed in a flexible, blanket-like form that can conform to different patient body shapes.

This provides several advantages:

· Improved patient comfort

· Flexible positioning

· Better anatomical conformity

· High RF element density

· Support for challenging examination positions

United Imaging specifically demonstrates SuperFlex Coil applications for the shoulder, elbow, hand, knee and other orthopedic examinations.

The flexible coil design is also intended to simplify pre-scan positioning and reduce the operational burden for technologists.
