Procurement Starting Point
Mammography procurement should protect image quality, dose control, patient comfort, reporting workflow, and QA documentation. The detector and workstation package matter as much as the acquisition unit.
Use this buying guide after the hospital has reviewed the main Mammography knowledge hub. The main page explains clinical use, workflow, components, maintenance, failures, lifecycle planning, and site-readiness background; this page converts that background into procurement decisions, RFQ clauses, scoring prompts, and vendor clarification questions.
The procurement file should make one thing clear before commercial comparison begins: what configuration is required, what is optional, what the vendor must prove, and what the hospital must prepare before installation.
Define Before Buying
- Screening, diagnostic, tomosynthesis, biopsy, or mixed breast imaging service
- Expected daily volume and reporting workflow with priors
- Need for stereotactic biopsy, contrast mammography, or tomosynthesis
- QA, accreditation, dose documentation, and workstation requirements
User Requirement Checklist
- Radiologists confirm reporting and tomosynthesis needs
- Technologists test positioning, compression, paddle workflow, and patient comfort
- Biomedical reviews detector, compression, QA, PM, and service support
- IT confirms PACS, priors, workstation, and storage capacity
Mandatory vs Preferred Specifications
Mandatory specifications should describe patient safety, minimum clinical capability, compatibility, uptime protection, and site fit. Preferred specifications should be scored separately so hospitals do not reject acceptable bids for features that are useful but not essential.
Mandatory requirements
- Detector performance, compression control, dose display, image processing, and QA tools
- Paddles, positioning accessories, workstation, DICOM/PACS, and priors workflow
- Tomosynthesis if approved as mandatory service
- Warranty/service for detector, compression system, workstation, and software
Preferred or scored requirements
- Biopsy option where service line is approved
- Contrast mammography where radiology protocol and infrastructure exist
- Advanced workstation tools where reporting volume justifies cost
Configuration Choices
Ask vendors to price the base configuration and the optional packages separately. This prevents a low base price from hiding software, accessories, site work, or service items that will be needed after award.
| Choice | When to Select | Procurement Risk |
|---|---|---|
| 2D digital mammography | Basic screening or diagnostic service | May limit modern breast imaging pathway. |
| Digital breast tomosynthesis | Screening and diagnostic programs needing 3D workflow | Higher storage, workstation, and licensing cost. |
| Biopsy-capable mammography | Diagnostic breast center with intervention | Needs accessories, training, QA, and room workflow. |
Vendor Comparison and Demonstration
Run the same demonstration script for every shortlisted vendor. The demonstration should be scored by users, biomedical engineering, IT/PACS, facilities, and procurement where relevant.
Vendor comparison points
- Detector, compression control, paddle set, patient comfort, dose, and image quality
- Tomosynthesis package, workstation, storage, priors, and reporting workflow
- QA tools, accreditation documentation, and service support
- Detector warranty, compression system warranty, software updates, and post-warranty cost
Questions to ask during demonstration
- Show screening and diagnostic workflow including priors and PACS transfer.
- Show compression controls, paddle change, positioning, and patient safety features.
- Show tomosynthesis review and workstation tools if included.
- Show QA procedure, detector calibration, and service report format.
Technical Evaluation Criteria
The technical evaluation should reward evidence, not brochure wording. Each bidder should identify the exact datasheet page, user manual section, service statement, or site planning document that supports its response.
- Score image quality and dose with breast imaging users.
- Score workstation and priors workflow.
- Score QA documentation and detector support.
- Score biopsy option only if clinically required.
| Scoring Area | Evidence to Request | Why It Matters |
|---|---|---|
| Clinical fit | User sign-off from scripted demonstration and application list | Prevents buying a configuration that looks strong on paper but slows the department. |
| Technical compliance | Clause-by-clause response with datasheet or manual evidence | Makes vendor responses comparable and reduces post-award disputes. |
| Service readiness | Local engineer count, spare-parts plan, response time, PM schedule, escalation route | Protects uptime after warranty begins. |
| Lifecycle cost | Five-year price schedule for options, consumables, service, software, and major parts | Shows the real cost beyond the base purchase price. |
Accessories, Consumables and Options to Price
The quoted package should show what is included, what is optional, what is reusable, what is consumable, and what has a replacement interval. This is where many radiology tenders lose cost control.
- Paddles, compression accessories, biopsy kit, phantoms, QA tools, workstation, monitors, DICOM, storage
- Tomosynthesis, contrast, biopsy, reporting, and CAD/AI licenses where needed
- Detector replacement, software maintenance, PM, and service contract
Site Responsibility Matrix
Do not award until responsibility for room works, utilities, network, shielding, HVAC, delivery, third-party interfaces, and safety approvals is written down. A missing responsibility matrix usually becomes a variation order.
| Responsibility | Vendor Must State | Hospital Must Confirm |
|---|---|---|
| Room workflow | Patient privacy, positioning space, control area, and accessory storage | Clinical layout and infection-control process |
| IT/storage | DICOM, priors, workstation, tomosynthesis storage, reporting | PACS capacity and reporting workflow |
| QA and radiation safety | Phantoms, dose documentation, calibration, and QA records | Medical physics and quality team review |
| Service | Detector, compression, workstation, software support | Biomedical service plan |
Warranty, Service and TCO Comparison
Warranty and service comparison
- Separate detector, compression mechanism, workstation, monitors, software, and biopsy accessories.
- Clarify detector replacement cost, calibration, software updates, and QA support.
- Ask for PM and image-quality verification after service.
- Compare post-warranty service including workstation and software.
Total cost of ownership items
- Detector, workstation, tomosynthesis storage, biopsy accessories, QA tools, software, PM, and downtime
- Storage growth from tomosynthesis can affect PACS cost.
Acceptance Requirements Before Award
Acceptance conditions should be part of the tender, not negotiated after installation. Link final payment to configuration verification, safety checks, image or performance baseline, integration tests, user training, biomedical handover, documentation, and warranty start date.
- Verify detector, paddles, compression, workstation, software, accessories, and QA tools.
- Test image quality, dose baseline, compression function, DICOM/PACS, priors workflow, and training.
- Record QA baseline, warranty, PM schedule, and documentation.
Common Buying Mistakes
- Buying tomosynthesis without storage and workstation planning.
- Omitting paddles, biopsy accessories, phantoms, or QA tools.
- Ignoring detector warranty and replacement cost.
- Not testing priors workflow.
Buyer Checklist
- Read the main Mammography equipment page before finalizing technical clauses.
- Confirm workload, user group, room, utilities, IT integration, accessories, consumables, service model, and budget approval.
- Require clause-by-clause compliance with evidence and declared deviations.
- Score configuration, demonstration, site readiness, service, warranty, lifecycle cost, and acceptance evidence before opening commercial preference.
- Attach acceptance requirements and final payment hold points to the purchase order.
