What Is Included in an Imaging Equipment PM Visit?

June 9, 2026 · 6 min · Medical Imaging Specialists

A medical imaging equipment preventive maintenance visit should include a documented inspection of the system, safety and performance checks, cleaning where appropriate, review of error logs and service history, verification of key operating conditions, image-quality or function checks, and practical repair recommendations. The exact checklist depends on the modality, manufacturer, model, site conditions, and service agreement. A PM visit is not just paperwork. It should help the facility catch small issues before they become downtime.

That is the difference between a useful PM and a box-checking visit. The best preventive maintenance gives the operator, biomed team, and administrator a clearer picture of equipment risk.

What a PM visit is supposed to accomplish

The goal of preventive maintenance is simple: keep the scanner reliable, document its condition, and identify work that should happen before the next failure. For CT, MRI, PET/CT, X-ray, C-arm, DEXA, ultrasound, and cath lab equipment, the PM process should be built around the real system in front of the engineer.

That means the visit starts before a cover comes off. A qualified service team should review the modality, make, model, serial number, prior service history, recent symptoms, current usage, site conditions, and operator complaints. A high-volume CT in an emergency department does not have the same risk profile as a lightly used backup X-ray room.

If the facility is still deciding how often to schedule service, read MIS’s guide on how often medical imaging equipment should be serviced. The PM visit itself is the evidence that helps refine that schedule over time.

Inspection, cleaning, and operating-condition checks

Most PM visits include a physical inspection of the equipment and surrounding environment. The engineer is looking for wear, contamination, loose connections, damaged covers, blocked airflow, mechanical drag, fluid leaks, cable strain, overheating signs, room-condition problems, and anything that suggests the system is being pushed outside a healthy operating range.

Cleaning is modality- and model-specific. It may include filters, vents, accessible dust buildup, exterior surfaces, fan paths, workstation areas, table tracks, gantry-accessible areas, or other components where the manufacturer or service procedure calls for it. It should not mean random disassembly or improvised repair steps. Medical imaging systems include high voltage, radiation-producing components, superconducting magnets, precision detectors, and specialized electronics. PM work belongs with trained personnel using the correct procedure.

Environmental checks matter more than many facilities realize. Cooling, HVAC, humidity, power quality, dust, blocked airflow, and poor room layout can all shorten equipment life. A good PM visit should make those risks visible.

Performance checks and error-log review

The most useful PM visits connect physical inspection with system behavior. That usually means reviewing error logs, warning history, image-quality complaints, startup problems, failed calibrations, scan aborts, intermittent issues, and operator workarounds.

For CT, PM attention often includes the gantry, table movement, tube/cooling indicators, detector behavior, image quality, workstation function, power and cooling conditions, and repeated errors. A PM visit cannot guarantee a tube will not fail, but it can often identify warning patterns that deserve planning. MIS covers those risk signals in what causes CT tube failure and the CT-specific PM guide, what is included in a CT preventive maintenance visit.

For MRI, the checklist is different. The service team may review coils, table movement, gradient or RF-related complaints, cooling/chiller behavior where applicable, image artifacts, system room conditions, magnet-related indicators, and model-specific requirements. A facility planning MRI service should also understand the points in what is included in MRI preventive maintenance.

For PET/CT, X-ray, C-arm, DEXA, ultrasound, and cath lab systems, the scope changes again. The common thread is that PM should test the functions that affect operation, image quality, workflow, and uptime without pretending one universal checklist fits every modality.

Documentation the facility should receive

A PM visit should leave behind usable documentation. At minimum, the facility should know what was inspected, what was cleaned or adjusted, what checks were performed, what issues were found, what parts may be needed, and what follow-up is recommended.

Good documentation gives administrators and biomeds a record that the equipment is being maintained, creates a service history that makes future troubleshooting faster, and supports budgeting. If an engineer sees repeated cooling issues, tube-life concerns, table wear, detector problems, coil failures, or workstation instability, leadership needs time to plan repair, parts, replacement, or backup capacity.

Keep PM records practical. A certificate with no findings is less useful than a clear service note that says what was checked, what changed, and what needs attention.

What should be checked before MIS arrives?

Facilities can make a PM visit more productive by preparing the right information before the engineer arrives. Send the modality, make, model, serial number, site location, current symptoms, error messages, recent service notes, and operator complaints. Include PHI-free photos or screenshots if they help explain the issue. Do not send patient names, dates of birth, accession numbers, or images containing protected health information.

If parts may be involved, MIS’s medical imaging equipment parts team can help route the request, but diagnosis should come first when the root cause is not clear. Guessing at parts is an expensive way to keep a room down. For parts-request prep, see how to know which imaging equipment parts you need.

Common PM mistakes to avoid

The first mistake is treating PM as a calendar event instead of a risk review. If the system has active symptoms, do not wait for the scheduled PM. Call for service. Repeated errors, image artifacts, cooling alarms, unusual noise, scan aborts, worklist failures, or intermittent startup issues deserve attention before the next visit.

The second mistake is separating PM from parts planning. If a critical component is aging or hard to source, the facility should understand lead time, cost exposure, and replacement options early. MIS’s guide to refurbished imaging equipment parts availability explains why serviceability should be part of the equipment plan.

The third mistake is assuming every vendor means the same thing by “PM.” Ask what is included, what is excluded, how findings are documented, whether travel and labor are covered, how repairs are quoted, and who owns follow-up. A PM-only plan, full-service agreement, and time-and-materials relationship are different risk models. MIS explains the tradeoffs in medical imaging service contracts and on the service agreements page.

How PM feeds repair, replacement, and leasing decisions

Preventive maintenance is not only about keeping today’s system running. It also helps decide when repair still makes sense and when the facility should plan replacement, leasing, or backup capacity.

If a CT has rising tube risk, an MRI has recurring cooling issues, an X-ray room is becoming unreliable, or a PET/CT is creating repeated workflow interruptions, the PM record gives leadership evidence before the next outage. That evidence can support a repair quote, a service agreement, a parts plan, a refurbished replacement quote, or temporary capacity through mobile imaging leasing.

This is where MIS’s full-service model matters. Equipment sales, parts, service, installation, deinstallation, and leasing should not be separate conversations when uptime is on the line. A practical PM visit should point the facility toward the next right step, whether that is a simple repair, a better schedule, an inventory check, or a replacement plan through equipment quotes.

FAQ

Is preventive maintenance the same as repair?

No. Preventive maintenance is scheduled inspection, cleaning where appropriate, performance review, documentation, and recommendations. Repair addresses a known failure, active error, down system, damaged part, or image-quality problem.

How long does a medical imaging PM visit take?

It depends on the modality, model, checklist, room access, symptoms, and whether follow-up work is found. A basic X-ray PM is not the same job as a CT, MRI, PET/CT, or cath lab PM.

Should a facility wait for the next PM if the scanner still works?

Not if symptoms are appearing. Repeated errors, artifacts, cooling issues, scan aborts, unusual noises, intermittent worklist problems, or operator workarounds should be reported before the scheduled PM.

Does refurbished equipment need a different PM checklist?

The checklist should be based on the specific modality, make, model, age, refurbishment history, usage, and site conditions. Refurbished equipment does not automatically need excessive service, but it does need disciplined maintenance and good documentation.

What should I send before requesting a PM quote?

Send the modality, manufacturer, model, serial number, site location, current PM schedule, service history, symptoms, urgency, and PHI-free photos or screenshots. MIS can route the request through service, parts, service agreements, or contact.
