Digital mammography unit uMammo 870i

Overview
uMammo 870i integrates Contrast-Enhanced Mammography (CEM) and Contrast-Enhanced Guided Biopsy to enable a uCEM exam in approximately 7 minutes. The system aims to reduce waiting times for diagnosis, improve lesion characterization to differentiate benign from malignant findings more effectively, and provide a workflow suitable for both high-tier hospitals and decentralized/private settings.

Features & Benefits

• Contrast-Enhanced Mammography: fast CEM exam (≈7 minutes) offering improved differentiation between benign and malignant conditions, reducing repeat exams and unnecessary biopsies.
• Contrast-Enhanced Guided Biopsy: targets enhancing (active) lesion regions to avoid necrotic tissue, improving biopsy accuracy and reducing repeat procedures; entire biopsy process can take ~20–30 minutes depending on procedure type.
• Dual-angle Tomosynthesis: supports 15° (fast, low-dose screening) and 40° (HD diagnostic) modes for tailored imaging per lesion type.
• Workflow efficiency: on-demand switching between scan modes, reduced exam/biopsy times versus MRI-guided or traditional FFDM-biopsy workflows.
• Patient-centric design: intelligent adaptive compression that releases immediately after exposure, one-touch positioning to simplify technologist operation, and elements designed for patient comfort.

Clinical Applications

• Mass detection and characterization — improved visibility and edge clarity, especially in DBT/40° mode.
• Calcification assessment — enhanced morphology visibility in DBT and CEM subtraction images.
• Asymmetry evaluation — DBT improves depiction and spatial localization of focal asymmetries.
• Architectural distortion — tomosynthesis and CEM enhance detection of structural distortions.
• CEM (uCEM) — subtraction images highlight heterogeneous enhancement consistent with malignant lesions, aiding diagnosis and biopsy targeting.
• Biopsy — supports uStereo, uTOMO and uCEM-guided biopsy workflows for microcalcifications and enhancing lesions.

Patient Comfort & Workflow Enhancements

• Intelligent Adaptive Compression: automatic stop at the ideal moment and immediate release after exposure to minimize discomfort.
• One-touch Positioning: simplifies gantry adjustments and reduces repeated movements by technologists.
• Design elements for comfort: breathing light, patient armrest, intelligent opposite position function to assist comfortable positioning.
• uDose intelligent dose control: individualised dose algorithm with full-panel AEC pre-exposure to optimise dose for different breast types.

Biopsy Systems & Guidance

• uStereo Biopsy: ±15° one-click stereoscopic imaging with auto depth calculation and auto lesion positioning; supports ±1 mm biopsy target accuracy.
• uTOMO Biopsy: dual-angle tomosynthesis-guided biopsy (small angle for calcifications, large angle for masses) enabling faster procedures and reduced dose compared with FFDM-biopsy.
• uCEM Biopsy: contrast-guided biopsy alternative to MRI-guided biopsy, offering targeted sampling of enhancing tissue and more convenient workflow.
