Buying Guides & Maintenance Tips

Ultrasound systems vary enormously in price and capability, and the "best" machine depends entirely on what your department actually scans. Before comparing quotes, work through these five factors.

1. Probe compatibility

Confirm the console supports the specific probe types your clinicians need — convex for abdominal/obstetric work, linear for vascular and small-parts imaging, endocavity for gynecological studies. A system that only ships with one probe port will limit you later.

2. DICOM and PACS integration

If your facility already runs a PACS (Picture Archiving and Communication System), verify the ultrasound machine outputs standard DICOM 3.0 — otherwise images will need manual export, which slows down reporting and increases the chance of lost studies.

3. Doppler capability

Color and power Doppler are essential for cardiology and vascular work but add unnecessary cost if your department only performs general abdominal or obstetric scans. Match the Doppler tier to your actual case mix.

4. Battery backup

In facilities with unreliable grid power, an internal battery that can complete an in-progress scan during an outage isn't a luxury — it protects both the exam and the patient from having to be rescanned.

5. Training and after-sales support

The most capable machine is only as good as the staff operating it. Ask your supplier what installation and training is included, and what the response time looks like if the probe or console needs repair.

Reactive repairs cost more than planned maintenance — both in parts and in the clinical downtime of a machine going unexpectedly offline. A basic preventive maintenance (PM) rhythm covers three cycles.

Daily / per-use checks

• Visual inspection for physical damage, loose cabling or unusual noise
• Confirm alarms and safety interlocks respond correctly before use
• Clean external surfaces and probes/handpieces per the manufacturer's protocol

Monthly checks

• Battery backup test — does the unit hold charge and switch over cleanly during a simulated outage?
• Filter and vent cleaning on any equipment with active cooling
• Verify consumables (paper, gel, disposables) are in-date and stocked

Quarterly / annual checks

• Formal calibration against manufacturer tolerance (critical for diagnostic and monitoring equipment)
• Electrical safety testing (earth leakage, insulation resistance)
• Full service by a certified biomedical engineer, with a written service report kept on file

Keeping a simple logbook per machine — even a spreadsheet — makes it far easier to spot a unit that's trending toward failure before it actually fails during a procedure.

ISO 13485 is the internationally recognized quality management standard specifically for medical device manufacturing and distribution. When a supplier claims this certification, here's what it should actually mean — and what to verify.

What it covers

The standard requires a documented quality management system across design controls, risk management, traceability of components, and corrective/preventive action processes. It's broader than a one-time product test — it certifies the process behind how equipment is made, stored and handled.

What it doesn't guarantee

ISO 13485 certifies a management system, not every individual unit's performance. It should be paired with product-specific regulatory clearance relevant to your country (in Nigeria, that's typically NAFDAC registration) before you treat a claim as complete.

Questions to ask your supplier

• Can I see the certificate, and does it list a certificate number I can verify with the issuing body?
• Is the certification held by the manufacturer, the distributor, or both?
• What local regulatory registration (e.g. NAFDAC) applies to this specific product?

A supplier confident in their paperwork will have no issue sharing certificate numbers and documentation on request — treat hesitation here as a red flag during procurement.
