Overview
uMR 680 is a research‑oriented large‑bore 1.5 T MRI system based on the uAIFI Technology platform. It combines DeepRecon deep‑learning reconstruction, EasySense contactless respiratory sensing and a 70 cm bore with gradient performance of 45 mT/m and 200 T/m/s to support advanced clinical and research protocols while enabling efficient exam workflows.

Core technologies / key capabilities

• uAIFI Technology: an integrated platform grouping reconstruction, sensing and workflow innovations to improve image fidelity and scanning efficiency.
• uAIFI DeepRecon: deep‑learning image reconstruction that increases SNR and apparent resolution, targeting "3.0T‑like" image characteristics on a 1.5 T system.
• uAIFI EasySense: contactless respiratory synchronization using dual‑source millimeter‑wave radar, enabling free‑breathing exams without belts (time resolution up to 20 ms, detection precision ~0.1 mm).
• QScan workflow: whole‑body quiet scanning workflow applicable to multi‑bed spine and whole‑body protocols.
• High performance gradient system: 45 mT/m amplitude and 200 T/m/s slew rate (simultaneous on axes) to support high SNR and high‑resolution protocols.
• High‑density RF channels: RF receiver architecture designed for high channel counts using dense surface coil arrays (page content lists up to 96 channels; technical table lists 72 channels).

Clinical applications and image examples

• Examples on the product page include Shoulder PDW FS (0.29×0.29×3 mm³), Knee PDW FS (0.35×0.35×3 mm³), Spine T2W STIR (1.11×1.11×4 mm³) and Cardiac T2W DB SPAIR (0.78×0.78×4 mm³), demonstrating comparable or improved acquisition times and spatial resolution versus conventional methods.
• Supports advanced research protocols such as 256‑direction DTI and ultra‑high b‑value DWI (e.g., b=10000) through optimized gradients and reconstruction.

Additional technical information

• Intelligent Noise Reduction: noise suppression integrated with DeepRecon to preserve diagnostic detail.
• Improved Image Sharpness: reconstruction and hardware improvements to enhance edge definition and detail.
• High Fidelity: quality verification in image and k‑space domains to ensure reliable results.
• Broad Field‑of‑View: supports large coverage exams including whole spine and multi‑bed whole‑body scanning.
