Procurement Starting Point
Vacuum plant procurement for pump redundancy, receiver capacity, alarms, infection-control safeguards, and PM.
Use measured/projected clinical demand and diversity; verify redundancy, receiver and filter sizing, exhaust safety, alarms, maintenance isolation, emergency connection, commissioning and service access.
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.
Clinical use should define modality-specific cases, patient volume, reporting workflow, emergency use, contrast workflow where relevant, and image storage/retrieval expectations.
Define Before Buying
- Clinical use should define modality-specific cases, patient volume, reporting workflow, emergency use, contrast workflow where relevant, and image storage/retrieval expectations.
- Review patient scheduling, preparation, acquisition, image reconstruction/review, DICOM transfer, reporting, archiving, repeat-image handling, cleaning, and downtime response.
- Confirm power, UPS policy, HVAC, shielding or MRI safety zoning, room size, control area, floor loading, delivery route, network drops, PACS/RIS readiness, and service clearance.
- Replace or expand when demand/redundancy is inadequate, vacuum or changeover is unstable, pumps/controls/alarms are unsupported, contamination/drainage issues recur, or overhaul and energy costs exceed renewal.
User Requirement Checklist
- Review patient scheduling, preparation, acquisition, image reconstruction/review, DICOM transfer, reporting, archiving, repeat-image handling, cleaning, and downtime response.
- Radiology users should test positioning, protocol selection, image review, dose or safety indicators, report/export workflow, contrast workflow where applicable, and ergonomic impact during peak lists.
- Demonstrate normal operation, alarm condition, changeover/bypass, emergency shutdown/isolation, service access, recordkeeping, and handover to facilities/biomedical teams.
- Review calculations, drawings, and commissioning test results with clinical area representatives.
Mandatory vs Preferred Specifications
Mandatory requirements
