uMR 680

System Overview

• 1.5T wide-bore system with "3.0T-like" performance empowered by uAIFI Technology
• High-performance hardware and software innovations for uncompromised clinical imaging
• Based on 3.0T-like hardware and uAIFI Technology — high-end clinical application solutions
• Designed for hospitals and imaging centres requiring advanced MR capability on 1.5T

Ultra-uniform Wide Bore & Patient Experience

• 70 cm wide bore reduces claustrophobia — comfortable for children, pregnant women, and obese patients
• Ultra-uniform magnet design for accurate off-centre and high-resolution anatomical imaging
• Magnetic field homogeneity: @50 cm DSV 0.831 ppm, @30 cm DSV 0.033 ppm (typical)
• Human-centered design integrating oriental aesthetics with minimalism and ergonomic comfort

3.0T-like Hardware Platform

• 45 mT/m gradient field strength and 200 T/m/s slew rate (simultaneous on each axis)
• 2.05 MW high-performance gradient power amplifier (GPA)
• 72+ independent RF receiver channels with new-generation high-density coils
• uCS 2.0 reconstruction — up to 16× acceleration, zero time-delay real-time reconstruction, 2.0 sec/phase temporal resolution

uAIFI DeepRecon, uCS & QScan

• DeepRecon — AI deep learning reconstruction for intelligent noise removal and fidelity imaging
• 1.5T system with 3.0T-like performance — high resolution, high SNR, and high speed simultaneously
• uCS × DeepRecon 2.0 — high-quality clinical images in significantly less time
• QScan — up to 97% reduction in acoustic noise; uCS × QScan 2.0 for silent imaging at same or shorter scan time
• Zero-deformation high b-value DWI up to b10000 and 256-direction DTI

Intelligent Workflow

• EasySense — dual-source millimeter-wave radar for contactless respiratory motion sensing (0.1 mm, 20 ms)
• EasyScan — intelligent automatic positioning for head, shoulder, cardiac, spine, abdomen, and knee
• EasyPlan — one-click multi-step scan planning and whole-body image stitching
• "PET-like" whole-body DWI imaging with EasyPlan — 0.6×0.6×5 mm³ in ~2:08 min

Advanced Neuro, Vascular & Body Imaging

• High-resolution 3D isotropic intracranial vessel wall imaging — 0.7 mm³, uCS 2.0
• Intelligent vessel wall post-processing — automatic centerline extraction, stenosis analysis, structured reports
• Supports cerebrovascular disease prevention, diagnosis, and prognosis evaluation
• Advanced body imaging including whole-body DWI, STIR fusion, and high-SNR abdominal protocols

Advanced Cardiac & Research Applications

• EasyScan Cardiac — automatic 7 standard planes; reduces positioning from 10 breath-holds to 1
• uCS Cine — single breath-hold whole-heart cardiac cine (SAX 16.7 s)
• T1/T2 mapping, automated ventricular contour extraction, bull's eye maps, and flow quantification
• Scientific research support — DTI (256 directions), DKI, UTE lung imaging, and Multiband
