Overview
DEXA scanner procurement for bone mineral density, T-score/Z-score reporting, positioning, phantom QA, dose, and service.
Evaluate precision, reproducibility, supported examinations, patient positioning, QA and calibration, analysis software, reference data, reporting integration, and local service—not only scan speed.
Separate mandatory clinical applications from optional software packages. Require site-planning documents, high-cost component warranty, DICOM testing, and acceptance image-quality baseline before award.
WHO procurement and technical-specification principles are used as the baseline: intended use, level of care, functional requirements, utilities, accessories, consumables, spare parts, environmental requirements, training, warranty, maintenance, documentation, standards, regulatory evidence, and decommissioning cautions should be addressed where relevant.
Required Specifications
- State exact intended use for dexa scanner, clinical location, workload, user group, required patient/application range where applicable, and level of care.
- Specify fan- or pencil-beam geometry, detector and scan field, supported sites and patient limits, precision and calibration workflow, body-composition capability if required, analysis software, reference databases, dose reporting, and DICOM/report export.
- Image-chain configuration, clinical application package, dose or safety controls where relevant, workstation/reporting workflow, DICOM/PACS/RIS connectivity, cybersecurity, and site planning requirements should be specified.
- High-cost components such as tube, detector, probe, coil, workstation, injector head, chiller, software licenses, and service tools should have clear warranty and replacement pricing.
- Clinical use area, workload, image acquisition configuration, reconstruction/display workflow, DICOM send/storage, modality worklist where required, cybersecurity update policy, and user access controls.
- Room readiness requirements including power, HVAC, radiation protection or safety zoning where applicable, network, equipment clearances, delivery path, and acceptance image-quality baseline.
- Service evidence covering PM frequency, calibration or QA tools, critical spare parts, local engineer response, downtime escalation, and software support.
- Name, category, and coding: generic name, specific type or variation, local naming/coding where available, and keywords linked to service area.
- Purpose of use: clinical or operational purpose, level of care, clinical department/ward, user group, and overview of functional requirements.
- Technical characteristics: critical measured or delivered parameters, ranges, displayed parameters, user-adjustable settings, alarms, compatibility, and interoperability.
- Physical and utility requirements: dimensions/mobility, electrical supply, battery, water, gas, drain, network, environmental operating/storage limits, humidity, dust, and transport/storage conditions.
RFQ wording examples
Use these examples to convert vague tender wording into measurable vendor responses. Adapt final clauses to the exact model, hospital workload, and local procurement rules.
Mandatory compliance
Weak wording
Equipment should be high quality and latest model.
Stronger RFQ clause
Bidder shall provide a clause-by-clause compliance matrix with comply, partially comply, not comply, or optional; each response shall include documentary evidence and cost impact.
Vendor evidence: Official datasheet, user manual extract, compliance matrix, itemized offer, and deviation list.
Evaluation note: Score measurable compliance and evidence. Do not score unsupported claims, brochure adjectives, or brand preference.
Lifecycle cost
Weak wording
Vendor should provide good service after warranty.
Stronger RFQ clause
Bidder shall submit five-year lifecycle cost including PM kits, consumables, major spare parts, batteries/sensors/probes where applicable, labor/travel, software support, and post-warranty rates.
Vendor evidence: Lifecycle price schedule, PM checklist, spare-parts list, service report sample, and escalation contacts.
Evaluation note: Compare total ownership cost and downtime risk, not purchase price alone.
Optional Specifications
- Advanced clinical applications, dose analytics, additional workstations, automated reporting/export tools, remote support, or uptime package where clinically justified.
- Additional detectors, probes, coils, accessories, software licenses, or room integration items priced separately.
Accessories
- Include calibration/QA phantom, positioning blocks and straps, table pad, workstation and printer/export, body-composition or orthopedic applications if required, DICOM license, and radiation-safety accessories.
- Price QA phantoms, positioning aids, probes/coils/detectors where applicable, injector accessories, software licenses, workstations, UPS/chiller items, DICOM licenses, and startup consumables.
- Patient positioning aids, workstation/licenses, DICOM/network accessories, QA phantoms or test tools where applicable, warning/signage items, and required startup consumables.

Compliance Requirements
- The bidder shall provide a clause-by-clause compliance matrix with documentary evidence for each mandatory and scored requirement.
- The bidder shall submit an itemized scope of supply, including main equipment, accessories, consumables, software/licenses, installation, commissioning, training, warranty, PM, spare parts, and exclusions.

- The bidder shall provide an acceptance and handover plan covering configuration verification, safety/performance inspection, user training, biomedical handover, inventory data, manuals, warranty certificate, PM schedule, and service contacts.
- The bidder shall identify the generic device name, specific type or variation, intended level of use, clinical department, and functional purpose so the Hospital Administration/Procurement/Biomedical Dept can confirm the offered device matches the actual service need.
- The bidder shall list utility requirements, environmental operating/storage limits, accessories, consumables, spare parts, packaging/labelling requirements, applicable standards, regulatory approval/certification, and decommissioning/disposal cautions.
