CT Scanner Service, Repair and Maintenance

Which CT Scanners Do You Service?

Service contracts, repairs and preventive maintenance are available for GE, Siemens, Philips, Canon, Fujifilm and Hitachi scanners whether or not the system was purchased from us, backed by more than 20,000 parts in stock and the engineers who rebuild our MO Select systems. What we work on most: For PET/CT, the CT half is serviced on the same terms; the contract shapes that cover the PET detectors are in how much PET/CT service costs on the PET/CT scanner cost guide. The CT half of a SPECT/CT is serviced the same way; what a nuclear medicine camera costs, by class, is in our nuclear medicine camera cost guide.

Slice count changes the workload more than the brand does, because a 64 or 128 slice system runs more studies and more scan seconds per week than a 16. Our explainer on CT scanner types by slice count and the comparison of CT scanner manufacturers cover the platforms in more depth. For a model not listed, tell us what you run; support depends on the platform and on parts availability.

How Fast Can a CT Engineer Reach Us?

Every minute a scanner is down is lost capacity, so the first response is remote and immediate. Our engineers are available 24/7 without automated phone trees: when you call (305) 885-4045 you speak to a trained professional who can start troubleshooting on the call.

• Emergency response Same-day or next-day service depending on urgency and location, with on-site diagnostics and troubleshooting to pinpoint the fault quickly
• Priority for contract clients Remote response within 30 minutes and on-site service within 2 hours for local facilities
• Component and board-level repair Restoring function without the expense of a full assembly replacement where the fault allows it
• Puerto Rico and the Caribbean Travel days and flights are part of the response time, so we plan them into the contract rather than discovering them when a system is already down
• Documentation Every repair is recorded with service logs and a post-repair summary, so your records are ready for an accreditation or regulatory review

On a CT the call that matters most is a tube fault: arcing, a loss of vacuum or an anode that will no longer spin means the scanner is off the schedule until a tube is fitted and calibrated, and the difference between one day of downtime and a week is whether the right tube is in stock. The next most common calls are detector and data acquisition faults that show up as rings or bands in the image, high-voltage generator faults, slip ring and gantry drive problems, table failures and cooling faults on a hot day.

What fails most often on a CT

The tube, and it is the single largest line item in a scanner’s life. Exposure and scan-second counts predict it far better than the year of manufacture, which is why tube condition and replacement terms are part of every quote we write. After the tube: detector modules, the high-voltage tank, the slip ring brushes, gantry and table motors, the cooling loop and the reconstruction computer.

What Does CT Scanner Preventive Maintenance Involve?

CT scanners require regular preventive maintenance and tube monitoring to stay compliant and minimise downtime. Visits run at manufacturer-recommended intervals, at night or during off hours where possible, and each one produces the documentation your accreditation body and state radiation program expect. A preventive maintenance visit on a CT covers:

• Tube and generator Tube warm-up and conditioning, scan-second and exposure counts logged against the tube’s history, high-voltage checks and cooling-oil condition
• Detector and image quality Air calibrations and detector checks, phantom tests for CT number accuracy, noise, uniformity, low-contrast and spatial resolution, and a check of the dose display against a reference
• Gantry and table Slip ring condition and brushes, gantry rotation and tilt, table drive, positioning accuracy and the laser alignment lights
• Cooling and power Chiller or air-cooling flow, filters, temperatures, line voltage and the uninterruptible power supply where fitted
• Safety and compliance Interlocks, emergency stops, warning lights, and the records your state radiation program and accreditation surveyor ask for
• Console and software Error logs, backups, protocol integrity, software patches and connectivity to PACS, the injector and the worklist

All maintenance work follows the manufacturer’s specifications with OEM parts and procedures, and the documentation proves it. That is what keeps a warranty valid, and it is what an accreditation surveyor wants to see next to the physicist’s annual report. Room requirements, shielding and power for a CT suite are covered in the CT cost guide.

What Does a CT Tube Replacement Involve?

A CT tube is a consumable with a very long life, rated in scan seconds, and replacing it is the largest single service event the scanner will have. Whether the scanner has a documented tube with most of its life left is one of the first things we check on a used system, and whether a service contract covers the tube is the first thing to check on a contract. C-arms are serviced on the same terms; what a C-arm costs to buy and what a service contract covers are in the C-arm service contract cost section of our C-arm machine price guide.

• Diagnosis Arcing, vacuum loss, bearing noise or a failed rotor are confirmed against the error logs and the tube’s scan-second count before a tube is ordered
• The tube A new or refurbished tube to OEM specification, matched to the generator and the software revision of the scanner
• Fitting Removal of the old tube, fitting, cooling-loop and high-voltage connections, then the seasoning and warm-up cycle the manufacturer specifies
• Calibration Air calibrations and phantom tests so the images and the dose display are back on specification before the first patient
• Paperwork The tube’s serial number, scan-second baseline and the calibration results, filed with the service record

On a contract, tube coverage is what separates a cheaper agreement from a complete one. A contract with tube coverage costs more per year and removes the one bill that can rival a year of service; a contract without it is reasonable on a scanner with a young tube and a known scan-second count. We write either, and we tell you which one the numbers favour. For tube life by tube class in scan seconds, the warning signs of a tube near the end and what a replacement costs in 2026, read our explainer on how long a CT tube lasts.

CT Service Contracts: What They Cover and What They Cost

There is no one-size-fits-all plan at Medical Outfitters. We listen first, then build the plan around the scanner, its age, how hard it works and what your budget can absorb. Most plans still fall into one of four shapes, and it helps to know the vocabulary before you compare quotes.

Four things are separate line items and it is worth reading them separately, because a contract can look complete and still leave the expensive parts out:

• Parts Which are included, and whether the platform is still supported by the manufacturer
• Labour On site and remote
• Travel Frequently billed separately, and the line that matters most for a remote or island site
• Response time A stated commitment, not an intention
• The tube In or out, and if in, whether it is capped by value or by scan seconds
• Software and calibration Whether annual calibration and software support are included

A service contract is priced per year as a percentage of the system value, with or without tube coverage, and the percentage moves with the platform, its age, the response time you need and where the site is. Tell us the scanner, the scan-second count on the tube and your annual volume, and we will quote the plan shapes side by side, with and without the tube.

For the cross-modality picture, including the clause that decides most CT contracts, how uptime guarantees are written and how to negotiate one, read what an imaging equipment service contract covers and costs.

CT Parts: Stock, OEM Procedures and Platform Support

Downtime is decided by parts as often as by engineers. Medical Outfitters holds more than 20,000 parts in stock for MRI, CT, X-ray and more, ready to ship same day or next day from Miami, and every repair is performed with OEM parts and procedures so your manufacturer warranty stays valid and the documentation proves the work was done to specification.

For a scanner the parts that decide a repair are the tube, detector modules, the high-voltage tank and generator boards, slip ring brushes, gantry and table motors, cooling pumps and the reconstruction computer. Ask about platform support before you sign a contract, not after a failure: a widely installed, still-supported platform has a deep parts pool, and a rare or end-of-support model can be newer and still harder to keep running.

Where Do You Service CT Scanners?

Medical Outfitters is based at 8062 NW 66th St in Miami, Florida, and services CT and PET/CT scanners with its own field service engineers across Florida, the United States, Puerto Rico and the Caribbean. Where you are decides how a contract is written, so here is how the coverage actually works.

The Florida imaging equipment page lists the projects behind that coverage, and our guide to MRI installation in Puerto Rico and the Caribbean explains what changes on an island site: customs, freight routing, crane access and the travel days that belong in the response time.

Is It Worth Repairing an Older CT Scanner?

Parts availability decides this more often than age does. A widely installed, still-supported platform has a deep parts pool and engineers who know it; a rare or end-of-support model can be newer and still be harder to keep running. When a tube is due on a scanner that also has an ageing detector and no software support, the tube quote is usually the moment to look at the replacement economics in the CT scanner cost guide.

A refurbished replacement usually costs 40 to 60 per cent less than new. Refurbished GE and Siemens scanners come through MO Select, new Fujifilm scanners through our dealership, and current stock is on the CT scanners for sale page. We also buy used CT scanners and remove them ourselves, and mobile and interim CT keeps you scanning while a room is out of use. Our guide to moving an MRI or CT scanner covers what a relocation involves. What each Siemens CT platform costs refurbished is in our Siemens CT scanner price guide. What an interim mobile CT costs to rent by slice class, and when buying beats renting, is in our mobile CT scanner rental guide. What a used scanner recovers against its band, and how to sell it, is in our guide to sell or trade in used imaging equipment.

Request CT Service or a Contract Quote

Two ways to reach the service team. If the scanner is down, call (305) 885-4045: engineers are on call 24/7. For a preventive maintenance schedule, a contract quote or a fault that is not urgent, the form below reaches the same coordinators and a specialist replies within one business day.

What to have ready shortens the first call:

• The manufacturer, model and slice count, and the system serial number
• The error messages and when they started, whether the scanner still boots and warms up, and any change in image quality
• The tube’s scan-second count if you have it, and the date of the last tube change
• Whether the system is under a manufacturer warranty or another contract
• The site address and access hours; for a contract quote, annual study volume and the response time you need

What a CT Scanner Service Contract Costs

A CT service contract cost is set per year as a percentage of the scanner’s value, and on a CT the percentage follows the tube before anything else: a contract with the tube covered is a different price from the same contract without it, because the tube is the single largest service event in the scanner’s life. After the tube come the coverage tier, the platform and its age, the detector, the response commitment and the site. Medical Outfitters does not publish a CT service contract price; every CT scanner service contract is quoted per site, in writing, with and without the tube. This section gives you the vocabulary to compare quotes: the four coverage tiers, what each includes and excludes on a CT, the lines that move the percentage, the response commitments in words, what to confirm before you sign, and an industry rule of thumb, labeled as an estimate for comparison only.

The plan shapes above are the contract forms we write; the tiers below are how the market prices them, and the questions behind a CT service search, CT service contract cost, CT scanner maintenance cost and what CT service includes, come back to the same table.

Industry rule of thumb for CT service contract cost (estimated, comparison only)

Industry rule of thumb for a CT service contract, estimated and printed for comparison only, from published trade-press and planning benchmarks; no Medical Outfitters figure is published.

How a CT service contract is priced

The percentage is applied to the value of the scanner as it stands, so a refurbished 16-slice and a new 128-slice on the same tier are different numbers, and the following lines move it up or down.

• The tube. Rated in scan seconds, replaced as the largest single service event in the scanner’s life, and the reason the two upper tiers differ; the tube replacement section above explains what a replacement involves, and the contract states whether the tube is in, out, capped or prorated.
• Slice count and volume. A 64 or 128-slice system runs more studies and more scan seconds a week than a 16, so it consumes tube life and parts faster and is priced accordingly.
• The detector and the data acquisition system. Detector modules are the next largest line after the tube and are not automatically inside a contract; they are named, capped or out.
• Platform and age. A widely installed, still-supported platform with a deep parts pool and tubes available new and refurbished prices lower than a rare or end-of-support model of the same age.
• Response and coverage hours. Weekday business hours with next-day on-site response is the base; evenings, weekends and a two-hour on-site commitment are buy-ups, and an uptime guarantee is priced as a tier.
• Site and travel. Travel is billed separately on many contracts and is the line that matters most for an island site; Medical Outfitters plans the travel days for Puerto Rico and the Caribbean into the contract rather than billing them per call.
• Term and fleet. A multi-year term and more than one scanner under one agreement lower the per-year rate.
• Software, calibration and service access. Annual calibration, software support and the manufacturer’s service keys are separate lines on some platforms, and must be inside the contract if your own engineers will work on the scanner.
• The purchase side. The CT scanner cost guide’s running-cost section sets out what each class is worth and why the service contract and the tube dominate what a CT costs to run.

Response commitments, in words

A contract states the hours it covers, how fast the first remote response comes, how fast an engineer is on site and, on the higher tiers, an uptime guarantee with a remedy if it is missed. Published manufacturer tiers in the United States run from a basic plan with next-day on-site response and an uptime guarantee in the low nineties, through a standard plan at four hours and 95 percent, to a premium plan at two hours and 98 percent, each measured during stated weekday coverage hours with evening buy-ups, and preventive maintenance labor is often billed separately even on the top tier. Uptime is counted only during the contracted hours, the clock usually starts when the call is logged, scheduled maintenance, tube replacement and site-caused downtime are excluded, and the remedy is often a contract extension rather than a refund.

The Medical Outfitters commitment is the one written into our contracts and stated on this page: remote response within 30 minutes and on-site service within 2 hours for local facilities on a contract, travel days planned into the contract for Puerto Rico and the Caribbean, and engineers on call 24/7; the response section above sets it out.

What to confirm on a CT service contract quote

Two CT service contract quotes at different prices usually differ in scope rather than in the engineers, so read these lines before comparing the numbers.

• The tube clause: in or out; if in, the cap by value, by scan seconds or by count, whether a prorated credit applies, and whether a refurbished tube is allowed.
• The detector and the data acquisition system: named inside, capped or out.
• The parts list and any cap, and whether the platform is still supported by the manufacturer.
• Coverage hours, remote response time and on-site response time, by region, with travel billed or included.
• The uptime guarantee: the percentage, which hours count, when the clock starts, what is excluded and the remedy.
• The preventive maintenance schedule against the manufacturer’s interval, tube monitoring, and a written report for every visit, because that paperwork is what the state radiation program and the accreditation surveyor ask for.
• Software support, annual calibration and service access.
• Term, renewal terms and what happens at end of support.

Tell us the scanner, the scan-second count on the tube and your annual volume, and we will quote the tiers side by side in writing, with and without the tube; the request form on this page reaches the same coordinators and a specialist replies within one business day. On a PET/CT the CT half is priced the same way and the PET detector modules join the tube as the line to read; how much PET/CT service costs on the PET/CT guide sets out the shapes.

Price Guides for the Other Modalities We Service

The engineers who service CT scanners install and service the other modalities too, and each has a price guide with refurbished and new ranges by model: the MRI machine cost and price guide, DEXA bone densitometer cost guide, X-ray machine cost guide, portable X-ray machine price guide, ultrasound machine cost guide, mammography machine cost guide and Neoprobe cost and buying guide. The 2026 Imaging Equipment Price Index puts every modality on one page.

CT Scanner Service and Repair: Common Questions

Do you service CT scanners you did not sell?

Yes. Service contracts, repairs and preventive maintenance are available for GE, Siemens, Philips, Canon, Fujifilm and Hitachi scanners whether or not the system was purchased from us. What matters is whether the platform is still supported and whether parts, including the tube, are available for it.

How quickly can a CT engineer reach us?

Emergency response is same-day or next-day depending on urgency and location. Service contract clients get remote response within 30 minutes and on-site service within 2 hours for local facilities. For Puerto Rico and the Caribbean, travel days are planned into the contract. Engineers are on call 24/7 on (305) 885-4045.

How much does a CT service contract cost?

It is priced per year as a percentage of the system value, with or without tube coverage, and the percentage moves with the platform, its age, the response time you need and where the site is. Tube coverage is the line that separates a cheaper contract from a complete one, because the tube is the single largest service event in a scanner’s life.

What does a CT tube replacement involve?

Confirming the fault against the error logs and scan-second count, fitting a new or refurbished tube to OEM specification, the seasoning and warm-up cycle the manufacturer specifies, then air calibrations and phantom tests so image quality and the dose display are back on specification before the first patient.

Do you service PET/CT?

Yes. The CT half of a PET/CT is serviced like any CT; the PET detector ring and coincidence calibration are separate work and are quoted with the platform. We de-installed a Philips TF PET/CT at Cleveland Clinic Florida and supply mobile PET/CT for interim cover.

Can you provide interim CT while ours is down?

Yes. If a scanner is down, a room is being built or a system is being replaced, mobile and interim CT keeps you scanning while the fixed suite is unavailable. We supply the unit, deliver it, service it for the term and collect it.

Which parts of Florida do you cover for CT service?

Miami-Dade, Broward and Palm Beach counties are served by our own engineers from the Miami warehouse. Naples and Fort Myers are scheduled trips. The rest of Florida, including Orlando, Tampa, Jacksonville, Gainesville and St. Augustine, is covered on service contracts, and we work nationwide, in Puerto Rico and across the Caribbean.
