- Contrast Enhanced 2D (CE2D) with I-View software, alone or combined with 3D Diagnostic
- Stereotactic and tomosynthesis biopsy with the Affirm system
- Direct-capture amorphous selenium detector and HTC cellular grid that retracts for 3D and magnification views
- Split C-arm with vertical motion and motorized rotation
- Quantra breast density assessment and CAD with ImageChecker (2D, C-View and 3D)
- Ergonomic packages with motorized height adjustment, fingerprint login and barcode reader (depending on package)
Description
Selenia Dimensions is Hologic's digital mammography system, designed from the ground up for breast tomosynthesis, offering high image quality, high productivity and a range of advanced applications. The Genius 3D MAMMOGRAPHY exam is designed for earlier detection of breast cancer, clearer images of lesions, and fewer recalls and biopsies.
The platform is available in several packages (Avia 3000 for 2D only, 6000 and 9000) and can be upgraded as the facility's needs grow, from low-dose 3D imaging and 3D biopsy to Contrast Enhanced 2D co-registered with tomosynthesis.
