Digital. Accessible.

The uMI 550 makes digital PET/CT accessible to all. Built with uEXPLORER® PET technology inside, the uMI 550 enables academic level image quality in oncology, cardiology, and neurology scanning. Born with AI this system utilizes AI-empowered workflow and image reconstruction based on total-body data. This air-cooled system is designed to fit in your room with minimal infrastructure investment and is available for mobile units.

The large 24 cm axial digital PET field of view (FOV) provides exceptional image quality with 2.9 mm NEMA resolution that improves quantitative accuracy and small lesion detectability.

Improve Patient Care

The uMI 550, born with AI, enables high-speed scanning without sacrificing image quality by combining the advanced AI iterative reconstruction engine trained with uEXPLORER® total-body PET data and a predictive AI-empowered workflow.

Expand Clinical Efficiency

With automated quality control programs, multiple radiopharmaceutical support and United Imaging's unique collaborative lifecycle approach, we are "All-In" to meet your needs today and in the future.

Founded on Innovation

PET Detector

Integrated-Light-Guide Digital PET Detector

The Integrated-Light-Guide improves light collection efficiency and spatial resolution to achieve exceptional image quality.

80-slice CT with Z-Detector

The ultra-low noise design of the Z-Detector helps produce high image quality with low radiation dose.

AI is only as good as the data you train it with. The CNN-based iterative reconstruction engine trained with uEXPLORER total-body PET data, uAI HYPER DPR uses a pre-trained neural network to predict low noise PET images and improve image contrast.

uMI 550 bed positions 

Long Axial Field of View

The long axial 24 cm FOV and high system sensitivity enables whole-body scanning in 4 bed positions within 8 minutes. 

Mobile Goes Digital

A fully configured, air-cooled digital PET/CT with a mobile-specific workflow maximizes patient throughput to enable the ability to scan at multiple locations in the same day.

Innovation that Delivers
Designed for Operational Excellence

The air-cooled uMI 550 digital PET/CT maintains a stable temperature environment for consistent detector performance with minimal infrastructure investment. The digital detector design with low-voltage power uses less energy than the traditional PMT-based design with high voltage power.

Redefining Clinical Flexibility with CT

This fully configured 80-slice diagnostic CT produces high image quality with low radiation dose that can be used as a standalone or back-up CT for Radiology procedures.

Reduction of Repeat Exams

The data-driven head motion correction algorithm detects motion from list-mode data during patient scans and corrects motion blurring, accordingly, limiting the need to repeat scans.

Quality Control Made Easy

No radioactive sources are required for automatic daily QC, reducing radiation exposure to the operator. Periodic full QC supports both liquid 18F and solid 68Ge sources.
