Mammography Decommissioning
End-of-life retirement of a mammography unit. Smaller scope than CT or MRI decommissioning, but with its own discipline: a-Se detector hazmat handling, MQSA accreditation closeout, and paddle / accessory inventory that often gets overlooked. Annual MQSA physicist survey records form part of the regulatory file.
Disposal items
- Amorphous selenium (a-Se) flat-panel detector — selenium is toxic; flat panels also contain other heavy-metal coatings. Do not dispose in general waste. Use a certified medical-equipment recycler with selenium-detector experience. Some manufacturers (Hologic, Siemens) operate take-back programs. See Clarity HD detector for the modern Hologic example.
- CsI / a-Si flat-panel detectors (older or non-Hologic platforms) — cesium iodide scintillator on amorphous silicon; recycle through certified medical-electronics recycler.
- X-ray tube — lead-filled housing, hazmat. Resale value if exposures / heat-units are low and the tube is current-generation. Mammography tubes (Mo / Rh / W targets) are a smaller refurb market than CT but exist.
- Compression paddle inventory — full set of paddles (CC, MLO, spot, magnification, biopsy, true-lateral, fenestrated) typically retained for the next system or sold separately. Cracked paddles discarded — keep documentation for MQSA file.
- Acquisition workstation + review monitor — data sanitization per HIPAA. Mammography review monitors (5MP grayscale) retain meaningful resale value if calibration history is clean.
- Stereotactic biopsy attachment (if equipped) — Affirm / equivalent biopsy package has independent resale value; document separately.
- Generator + cabinet — recyclable, low individual resale value.
Data sanitization
- HDDs / SSDs on the acquisition workstation, review workstation, and CAD / AI server destroyed or certified-erased per HIPAA.
- DICOM cache wiped; PACS retention obligations satisfied via migration before removal.
- CAD database (e.g., R2 ImageChecker, ProFound AI legacy) archived per state law.
Regulatory + accreditation
- MQSA facility deregistration at unit retirement is the central regulatory event. The MQSA accreditation file (annual physicist survey, daily / weekly QC binder, lead-apron survey, paddle inspection records, image-quality phantom records) is retained per FDA requirements after closure.
- State X-ray-machine registration amended at decommissioning.
- ACR accreditation — separate accreditation file (where applicable) updated.
- 3D / C-View / biopsy / contrast-enhanced (CEM) license tier — software entitlements typically transfer with the unit on resale; document for the file.
Resale and parts recovery
- Working units with current detectors and 3D / C-View licensing have meaningful refurb resale value globally; community and developing-market demand absorbs the supply.
- Detector age and condition is the price-determining variable. Detectors >5 years old or showing artifacts may not transfer with the unit.
- Paddle inventory is sometimes worth more separately than with the unit, depending on buyer.
- Stereotactic biopsy attachment has its own market.
Operational reality
- Decommissioning is fast compared with CT / MRI / linac — units are physically smaller, no shielding teardown beyond the lead-glass operator window, no activation cool-down.
- MQSA paperwork takes longer than the equipment removal in most cases.
- Refurb pipeline absorbs most retired units; outright scrap is unusual unless the detector has failed.
