Whole-body tomography MRI system uMR 790

for brain tomographyhigh-fieldAI-assisted

Product overview
uMR 790 is a United Imaging 3.0T magnetic resonance imaging system designed for research and high‑end clinical applications. It is intended for large‑sample, multicenter brain‑science and clinical research scenarios, focusing on high‑definition imaging and stable underlying data, and integrates the uAIFI technology platform to support whole‑body clinical and research workflows.

Core features

• Research‑grade superconducting magnet with enhanced homogeneity to improve image quality and SNR.
• Exploratory gradients with high amplitude, linearity and precision to provide a stronger gradient “engine”.
• uAIFI Inside: brain‑like technology platform supporting advanced post‑processing and intelligent analysis.
• Dedicated capabilities for high‑resolution neuro and vessel‑wall imaging: supports ultra‑high b‑value diffusion (up to 35,000), head–neck unified vessel‑wall imaging at 0.4 mm voxel, and ultra‑high‑resolution neuro anatomy down to 0.1 mm.
• High‑density dedicated coils to improve resolution and SNR for deep and small structures.

Hardware platform
Designed as a research‑oriented high‑performance system: exploratory magnet and gradients provide the hardware basis required for high‑performance research imaging, addressing the design and manufacturing challenges of high‑amplitude, high‑linearity and high‑precision gradient coils to deliver improved image quality and more stable underlying data acquisition.

Neurology / brain‑science applications

• Ultra‑high b‑value diffusion imaging (enabled by the exploratory gradients, supporting b up to 35,000) with deformation control while preserving SNR.
• BrainTool intelligent brain analysis: deep‑learning based whole‑brain segmentation and multimodal quantification (for research exploration; not indicated as clinical diagnostic tool).
• Precise subregion segmentation: automatic segmentation of 106 brain substructures.
• Abnormality detection: automatic identification of atrophy/dilation based on normative database.
• Multidimensional quantification: transfer of region‑based quantitative functional parameters via segmentation and registration.

Vessel‑wall and head–neck imaging
Combined with the high‑performance system and high‑density dedicated coils, uMR 790 can acquire head–neck unified vessel‑wall imaging with 0.4 mm isotropic voxels in short scan times, significantly improving anatomical resolution and SNR of deep intracranial and cervical vessel walls.
