Ultra-low Noise Design

With highly integrated architecture, Z-Detector not only achieves overall noise reduction, but also helps to ensure high image quality with low radiation dose.

High-performance Material

The high conversion efficiency of GOS boosts X-ray conversion rate while maintaining quick response time.

Fine Sampling

The very fine sampling voxels acquire massive information, bringing exquisite visualization of fine anatomic details.

Low Dose

High sensitivity boosts data acquisition and enables low-dose PET scans.

Intuitive Workflow for Efficiency

Automatic Quality Control Workflow

No radioactive source is required for automatic daily QC, reducing radiation exposure to the operator. Periodic full QC supports both liquid 18F and solid 68Ge sources with lower storage condition requirements. A fast NEMA tool makes the workflow convenient and efficient.

Head Motion Correction

Without the requirement for external devices, the data-driven motion correction algorithm detects motion from list-mode data during patient scans and corrects motion blurring accordingly.

Intelligent Motion Artifact Reduction

Without an external gating device, the intelligent digital self-gating technology automatically detects respiratory motions. MAC helps reduce metal artifacts and keep the important surrounding structural details.

Integrated Oncology Application

The uMI 550 offers a comprehensive solution package for tumor diagnosis and post-therapeutic evaluation on the operation console.
