Product Description

The uMammo 890i is an advanced low-dose 3D digital breast tomosynthesis system designed for early detection and accurate diagnosis of breast cancer. The system integrates a high-definition CMOS detector, intelligent dose control technology, and dual-angle tomosynthesis imaging to deliver exceptional image clarity while minimizing radiation exposure.

The system provides both 3D tomosynthesis imaging and synthesized 2D mammography, enabling radiologists to visualize breast structures at different depths and detect small lesions, calcifications, and architectural distortions more effectively.

With an intelligent workflow design, AI-assisted diagnostic tools, and a stereotactic biopsy system, the uMammo 890i supports a complete breast imaging solution from screening to diagnosis and biopsy guidance.

Key Features

1. HD CMOS Detector

The high-resolution CMOS detector provides 10.1 lp/mm spatial resolution and 49.5 μm pixel size, enabling clearer visualization of micro-calcifications and small lesions.

2. Low-Dose 3D Tomosynthesis

Dual-angle tomosynthesis technology captures multiple low-dose projection images to reconstruct high-resolution 3D breast images while maintaining radiation dose comparable to conventional FFDM.

3. Dual-Angle Imaging Modes

Two tomosynthesis scanning modes are available:

• 40° wide-angle mode for diagnostic imaging

• 15° narrow-angle mode for rapid screening

This flexible imaging capability improves both diagnostic confidence and workflow efficiency.

4. uDose Intelligent Exposure Control

The full-panel automatic exposure control (AEC) analyzes the entire breast gland area to determine the optimal radiation dose, improving image quality while reducing unnecessary exposure.

5. AI-Assisted Diagnosis

AI algorithms assist in breast density analysis, lesion detection, and report generation, improving radiologists’ diagnostic efficiency and consistency.

6. Integrated Stereotactic Biopsy System

The optional uStereo biopsy system provides precise needle guidance with positioning accuracy up to ±1 mm, supporting accurate tissue sampling for pathological diagnosis.

7. Patient-Centric Design

The system includes:

• Intelligent adaptive compression

• One-touch positioning

• Curved armrest and breathing guidance light

These features improve patient comfort and simplify operation for technologists.
