Selenia Dimensions 2D3D

Breast Imaging for Today and Beyond.The Selenia Dimensions 2D system is the ideal choice for centers that want a flexible digital breast imaging platform with state-of-the-art image acquisition and display features.Digital Mammography and Breast Tomosynthesis from Hologic.Selenia Dimensions starts with technology similar to that of our celebrated Selenia full-field digital mammography system. With its large amorphous selenium detector, it too can “direct capture” conventional digital mammograms with the same extraordinary clarity you’ve come to expect from Selenia. And incorporating a tungsten tube means we can do it with even less patient radiation dose than before. But Selenia Dimensions takes you to the next step in detection: fast, low-dose, high-quality tomosynthesis images of the breast.

Benefits

• Tomosynthesis Benefits
• Removes overlapping structures
• Increases lesion visibility
• Facilitates margin analysis
• Helps localize structures
• Tomosynthesis Outcomes
• Reduces recall rate (increased specificity)
• Potential to increase cancer detection (increased sensitivity)
• Image Resolution
• Reconstructed pixel size of 90µm is superior to original detector resolution
• Images are acquired at 140µm
• Resolution optimized for display on tomo-enabled workstations
• Image quality proven through multi-center clinical trials

Features

• Proven Technologies
• Direct Conversion Detector – Optimal Pixel Size
• Preserves image sharpness by completely eliminating the image-degrading effects of light diffusion
• 70 Micron pixel pitch, the most effective pixel size for visualization and characterization of smallest microcalcifications
• Ongoing detector optimization program ensures enhanced stability and longevity
• HTC Grid
• Cross-hatch design reduces scatter in X & Y direction
• Allows 70-80% transmission of primary beam
• Grid automatically retracts for magnification and tomo views
• Goes from screening to diagnostic or tomo to 2D imaging in ~ 2 seconds
• Grid never has to be handled, eliminating potential for damage
• Optimized Tube Technology
• Bi-angular tungsten (W) x-ray tube
• Rhodium (Rh) filtration for most breast types
• Silver (Ag) filtration for breasts over 7 cm (compressed)
• Tungsten dose: 1.0 – 1.2 mGy
• W-Ag combination optimal for larger breasts*
• Reduced dose without increasing exposure time
• Decreases likelihood of patient motion
• Innovative AEC
• Intelligent tissue selection using two sensing areas for optimum technique selection
• 15 cm travel from chest wall
• Accommodates imaging of larger breasts
• FAST Paddles
• Provides proper and consistent compression across the entire breast without over-compression at the chest wall
• Reduced motion artifacts
• More uniform compression
• Maximum patient comfort
• Smart Paddle System
• Smart Paddle System and fully automatic collimation allows small breasts to be imaged on large detector
• When paddle is shifted, AEC and collimation automatically moves to proper position
• Optimized Detector always ready to acquire images
• Latest, innovative selenium detector technology
• Stable, long lasting detector
• Ultrafast electronics for instant image read
• Self-contained cooling system for independent temperature control
• Independent power cycle for instant-on operation
• High Patient Throughput without compromising patient care
• High resolution preview image available 4 – 6 seconds following end of exposure
• Rapid detector recycle time
• Move from image to image without delay
• Flexibility to accept, reject, or pend images
• Ergonomic Design for enhanced patient comfort
• Slim tubehead for easier, more comfortable positioning
• 70 cm SID to facilitate interventional procedures
• Easy access for wheelchair or stretcher
• Recessed area on each side of C-arm for natural positioning of hands
• Compression Paddle Innovations streamlined workflow
• Lightweight, plastic-only paddles install directly on compression carriage; simply change plastic to move from paddle to paddle.
• Each paddle registers through miniscule, surface-mounted electronics
• Efficient Display
• SecurViewDX 400 workstation optimized to view tomosynthesis images
• Supports tomo, 2D, combined 2D+tomo, and tomo projections
• Multiple display options to facilitate efficient review
• Slices, stacks, cine, slabbing
• Co-registered 2D + tomo display toggling
• 2D CAD displayed on tomo slices
• Networking Considerations
• 100 Mbps may be acceptable, depending on overall traffic
• 1 Gbps switched network is more than adequate for handling this volume of data
• Web-based PACS clients may not be able to handle the transmission and display of tomo data
