How to Choose the Best Digital Mammography Machine

Types of mammography machine

The main types are analogue film-screen units, computed radiography systems, full-field digital mammography (FFDM), digital systems with tomosynthesis and units with contrast or dual-energy capability. In practice, new purchases in hospitals are digital, with the real choice being 2D only, field-upgradable, or tomosynthesis as standard.

A field-upgradable unit such as the Villa Melody IIID can be configured with a-Si or a-Se detectors and upgraded in the field to tomosynthesis, tomo-guided biopsy and Dual Energy. The Melody IIID TS has 3D tomosynthesis built in. For more on the technology see digital versus film mammography.

Detector, tube and image quality

The detector is the heart of the system. Ask for the detector type (a-Si/CsI or a-Se), pixel pitch, acquisition time and the dose per image on a standard phantom or equivalent breast. The Melody line offers an a-Si/CsI detector or an optional a-Se detector in Standard or Fast versions.

The tube, target and filter combination and the automatic exposure control decide how well the system manages dense tissue. Density-based automatic exposure control is listed for the Melody IIID. Judge image quality on clinical sample images reviewed by your own radiologists, not only on specifications.

• Detector type, pixel size and acquisition speed
• Tube target and filter combinations
• Automatic exposure control behaviour in dense breasts
• Dose reporting and DICOM dose structured report

Tomosynthesis readiness and biopsy options

Decide early whether tomosynthesis is required at opening or later. If later, insist that the upgrade path is described in writing with scope, downtime and cost basis. For the clinical case see digital breast tomosynthesis.

Biopsy changes the room and the workflow. A stereotactic system is optional on the Melody IIID, and the TS supports tomo-guided biopsy with the optional SBD DMD 3D device, with biopsy targeting accuracy of ±0.1 mm listed. Review the stereotactic biopsy explanation when defining your service line.

Ergonomics, compression and patient comfort

Comfort affects participation in screening. Check the compression system, the speed of motorised movements and the interface used by technologists. The Melody IIID has a fully motorised isocentric C-arm, decremental compression with Smart Micro Press and two touchscreen control panels.

Look at how easily different patient sizes and wheelchair users can be positioned, and whether the unit supports standard views such as CC and MLO plus additional projections. Include technologists in the demonstration.

Workstation, PACS and service

The acquisition station and reporting workstation determine reading speed. The Melody line connects to AESTIMAX or WorkstationONE reporting stations with optional AI tools, and the multimodality acquisition station provides full DICOM functions. Confirm compatibility with your PACS and RIS.

Finally, evaluate the supplier: installation, training, preventive maintenance, spare parts, remote support and response times in the UAE. Ask Beckfinity's specialists for a configuration that matches your volume, and read our related guides on machine cost and manufacturers.
