Procurement Starting Point
Angiography procurement should be treated as a procedure room purchase. Detector, tube, table, monitors, injector, hemodynamics, shielding, ceiling structure, UPS, DICOM, and staff protection all affect whether the room works after installation.
Use this buying guide after the hospital has reviewed the main Angiography System 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
- Procedure mix: diagnostic cath, PCI, electrophysiology support, peripheral vascular, neurointervention, stroke thrombectomy, EVAR, TAVI, or embolization
- Monoplane versus biplane requirement and detector size by procedure type
- Required software: DSA, roadmapping, bolus chase, cone beam CT, dose reporting, vessel analysis, or 3D fusion
- Room integration scope: table, monitors, booms, injector, hemodynamic system, UPS, shielding, HVAC, and PACS/RIS
User Requirement Checklist
- Interventional users confirm procedure mix and patient access workflow
- Technologists confirm table, C-arm movement, pedals, monitors, image store, and dose display
- Biomedical engineering reviews tube, detector, C-arm movement, table, UPS, service, and downtime risk
- IT confirms DICOM, dose report export, hemodynamic interface, network, and cybersecurity
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 size, C-arm geometry, table capacity, generator/tube performance, and cooling suitable for approved procedure mix
- Pulsed fluoroscopy, DSA, roadmapping, collimation, last-image hold, and dose display/reporting
- DICOM storage, worklist, dose report export, and integration with injector and hemodynamics where required
- Room responsibility matrix covering shielding, ceiling support, power, UPS, HVAC, monitors, booms, and third-party interfaces
Preferred or scored requirements
- Biplane, cone beam CT, 3D roadmapping, fusion imaging, or advanced dose analytics where procedures justify the cost
- Large display walls, advanced monitor suspension, or hybrid room options when clinical workflow requires them
- Remote diagnostics and predictive service where cybersecurity and support contracts allow it
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 |
|---|---|---|
| Monoplane angiography | General interventional radiology, peripheral vascular, routine cardiac work | May limit neuro or complex procedures that benefit from simultaneous planes. |
| Biplane angiography | Neurointervention, stroke thrombectomy, complex pediatric or structural workflows | Higher room, ceiling, service, tube, detector, and shielding cost. |
| Cath/interventional room package | Cardiac cath, vascular, IR, or mixed service line | Integration gaps with hemodynamics, injector, monitors, and PACS can delay go-live. |
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 size, pixel size, DQE claims, frame rate, tube heat capacity, and cooling
- DSA, roadmapping, bolus chase, CBCT, fusion, and dose reporting package clarity
- Table movement, C-arm parking, monitor layout, pedal workflow, and emergency patient access
- Tube and detector replacement price, uptime commitment, critical spare strategy, and after-hours escalation
Questions to ask during demonstration
- Show a complete PCI, peripheral, or neuro workflow based on the tender scope.
- Show DSA, roadmapping, dose display, dose report export, and image transfer.
- Show table/C-arm movement, collision avoidance, monitor positioning, and emergency patient access.
- Show integration points for injector, hemodynamics, PACS/RIS, and remote service.
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 monoplane versus biplane against actual procedure mix.
- Score tube and detector risk using warranty, replacement price, and lead time.
- Score dose workflow and radiation protection accessories as part of the clinical package.
- Score room integration evidence before commercial ranking.
| 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.
- Table accessories, pads, arm boards, radiation shields, ceiling shields, monitor suspension, large displays, pedals, and sterile covers
- Injector interface, hemodynamic interface, DICOM/worklist, dose reporting, CBCT, DSA, roadmapping, and analysis licenses
- UPS, room control, lead glass, shielding, ceiling support, HVAC, electrical works, and network points
- Tube price, detector price, PM kits, critical spare parts, and post-warranty service
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 integration | Layout, table, C-arm, monitor booms, ceiling support, shielding, control room, and equipment room needs | Civil/structural design, shielding consultant, construction schedule, and user sign-off |
| Power and UPS | Electrical load, UPS scope, grounding, emergency power, and shutdown behavior | UPS ownership, generator connection, panel capacity, and maintenance scope |
| Third-party systems | Injector, hemodynamic system, DICOM, dose report, and integration responsibility | Vendor coordination, interface licenses, network readiness, and acceptance witnesses |
| Radiation safety | Shielding inputs, staff PPE, ceiling shields, dose tools, and QA requirements | Radiation safety officer review, PPE procurement, and occupational monitoring process |
Warranty, Service and TCO Comparison
Warranty and service comparison
- Separate warranty for tube, detector, table, C-arm movement, generator, monitors, pedals, workstations, and software.
- Clarify tube and detector replacement cost, lead time, and image-quality verification after replacement.
- Require emergency response, after-hours escalation, uptime reporting, critical spare list, and PM windows.
- Compare comprehensive service pricing because angiography downtime can cancel urgent procedures.
Total cost of ownership items
- Tube and detector replacement exposure
- Software packages, monitor upgrades, injector/hemodynamic integration, and dose software
- Radiation protection accessories and PPE replacement
- Downtime cost for cath lab, IR, stroke, and vascular procedure capacity
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, tube, table, C-arm, monitors, software packages, injector/hemodynamic interface, and accessories.
- Record image-quality baseline, dose baseline, DSA/roadmapping performance, safety checks, and movement tests.
- Test DICOM, worklist, dose report export, PACS transfer, hemodynamic interface, and remote service controls.
- Complete user, biomedical, IT, facilities, and radiation safety handover before final payment.
Common Buying Mistakes
- Buying the imaging chain without buying the room integration package.
- Selecting detector size without matching procedure mix.
- Leaving hemodynamic, injector, dose report, or PACS integration undefined.
- Underweighting service response even though downtime directly affects procedure capacity.

FAQ
When should a hospital buy biplane angiography?
Biplane is usually justified for neurointervention, stroke thrombectomy, complex pediatric work, and procedures where simultaneous two-plane imaging reduces contrast, time, or risk.
What should be included in an angiography vendor comparison?
Compare detector, tube, table, C-arm movement, dose tools, DSA/roadmapping, CBCT if required, injector/hemodynamic integration, room scope, warranty, service response, and TCO.
What costs are often missed in angiography tenders?
Hospitals often miss monitors, booms, shields, UPS, lead glass, ceiling support, injector/hemodynamic interfaces, software licenses, tube price, detector price, and room construction responsibilities.
How should angiography acceptance be written in the tender?
Acceptance should require configuration verification, movement and safety checks, image and dose baseline, DSA/roadmapping tests, DICOM/dose export, integration tests, training, and handover.
Why is service support heavily weighted for angiography?
Angiography rooms support urgent cardiac, vascular, and neuro procedures. Tube, detector, table, or integration downtime can quickly cancel high-priority cases.
