Quick Answer: A CT scan machine typically costs $90,000 to $900,000 on the secondary market in 2026, and most facilities land in the $90,000–$400,000 range. The biggest factor is slice count: refurbished 16-slice CT machines commonly run $90,000–$170,000, 32/40-slice systems $130,000–$200,000, 64-slice workhorses $250,000–$400,000, and 128- to 256+-slice advanced scanners $400,000–$900,000. Buying refurbished typically saves 30–70% compared to new, which is why so many hospitals, imaging centers, and urgent care groups choose a certified pre-owned system from platforms like the GE LightSpeed and Revolution, Siemens Emotion and Definition, or Canon (Toshiba) Aquilion. This guide walks through how CT machines work, which slice count fits which caseload, and what the total investment really looks like.
How a CT Scan Machine Works, in Plain Language
A CT (computed tomography) scan machine is essentially a rotating X-ray system paired with a very fast computer. An X-ray tube spins around the patient inside the doughnut-shaped gantry while a bank of detectors on the opposite side measures how much radiation passes through the body from every angle.
As the table moves the patient through the gantry, the system captures thousands of these projections. The computer then reconstructs them into cross-sectional images — thin “slices” of anatomy — that can be stacked into detailed 3D views of bone, soft tissue, blood vessels, and organs.
Two numbers matter most when you compare CT scan machines as a buyer:
- Slice count — how many rows of detectors capture data in a single rotation. More slices mean faster scans, thinner images, and better coverage of moving organs like the heart.
- Rotation speed — how quickly the tube completes one revolution. Sub-half-second rotation is what makes cardiac imaging practical on 64-slice and higher systems.
Everything else — tube capacity, reconstruction software, dose-reduction packages — supports those two fundamentals. That is why the market organizes CT machines by slice count, and why pricing follows the same logic.
Types of CT Machines by Slice Count
Slice count is the single most useful way to sort CT machines for sale, because it maps directly to clinical capability. Here is how the tiers break down and who each one is right for.
16 Slice CT — General and Routine Imaging
A 16-slice CT scanner handles the bread-and-butter work that makes up the majority of CT volume at most facilities: head, chest, abdomen, pelvis, spine, sinus, and extremity studies. Scan times are longer than higher-tier systems, but image quality for routine diagnostic work is excellent.
Best fit: urgent care centers, orthopedic and general practices, veterinary facilities, rural hospitals, and imaging centers with modest daily volume. If you do not need cardiac imaging, a 16-slice system is often the smartest dollar-for-dollar buy in the entire CT market.
32/40 Slice CT — The Step-Up Middle Tier
The 32- and 40-slice tier delivers noticeably faster scans and thinner slices than 16-slice systems, which helps with trauma work, larger patients, and higher daily throughput. It is a practical middle ground for facilities that have outgrown a 16-slice machine but do not need full cardiac capability.
Best fit: busy outpatient imaging centers, community hospitals, and multi-specialty groups scanning a steady mix of routine and complex cases.
64 Slice CT — The Workhorse: Cardiac Capable and ER Ready
The 64-slice CT machine is the industry workhorse for a reason. It is the entry point for reliable coronary CT angiography and calcium scoring, and its speed suits emergency departments where trauma protocols, stroke workups, and pulmonary embolism studies cannot wait.
Best fit: hospitals with an ER, cardiology practices, and imaging centers that want one scanner to cover essentially every referral that walks in the door. On the secondary market, 64-slice systems offer the strongest balance of capability, parts availability, and resale value.
128 Slice CT — High Throughput and Advanced Protocols
A 128-slice system adds faster coverage, improved temporal resolution for cardiac work, and headroom for advanced applications like perfusion imaging. Facilities running high volumes or competitive cardiac programs often step up to this tier.
256+ Slice CT — Advanced Cardiac and Research
At 256 slices and beyond, a single rotation can capture the entire heart in one heartbeat. These scanners serve dedicated cardiac programs, academic medical centers, and research institutions where motion-free coronary imaging and specialized protocols justify the investment.
Slice Count at a Glance
| Slice Count | Best For | Cardiac Capable? | Typical Buyer |
|---|---|---|---|
| 16 Slice | Routine head, chest, abdomen, spine, extremity imaging | No (calcium scoring only on some configurations) | Urgent care, orthopedics, veterinary, rural hospitals |
| 32/40 Slice | Higher throughput, trauma, larger patients | Limited | Outpatient imaging centers, community hospitals |
| 64 Slice | Full-service imaging, ER/trauma, coronary CTA | Yes | Hospitals, cardiology, full-service imaging centers |
| 128 Slice | High-volume cardiac, perfusion, advanced protocols | Yes — improved temporal resolution | Larger hospitals, competitive cardiac programs |
| 256+ Slice | Single-heartbeat cardiac imaging, research | Yes — best in class | Academic centers, dedicated cardiac and research programs |
Portable and Mobile CT Machines
Not every CT lives in a fixed scan room. Two distinct categories serve facilities that need flexibility:
- Portable CT scanners are compact units that roll to the patient — typically used for head and neuro imaging in ICUs, operating rooms, and stroke units where transporting a critical patient is risky.
- Mobile CT trailers are full-power scanners built into a transportable coach. Hospitals use them during construction, equipment replacement, or seasonal volume spikes, and rural networks use them to share one scanner across several sites.
Portable units trade image coverage and power for mobility, so they complement rather than replace a fixed CT scan machine. Mobile trailers, on the other hand, carry standard 16- to 64-slice systems and can shoulder a facility’s full caseload on an interim basis — more on mobile CT rentals later in this guide.
Major CT Platforms: GE, Siemens, Canon, and Philips
Four manufacturers dominate the CT machines you will see on the secondary market. All four build excellent scanners; the practical differences for buyers come down to parts availability, service network depth, and which platform your technologists already know.
GE HealthCare
The GE LightSpeed family (including the LightSpeed PRO) has been a secondary-market staple for years thanks to enormous installed volume and deep parts availability. The GE Optima CT-660 is a popular 64-slice step-up with strong dose-reduction features, and the GE Revolution line represents GE’s premium tier for cardiac and high-end applications.
Siemens Healthineers
The Siemens Emotion series (6- and 16-slice) is known for reliability and low operating costs, making it a favorite for routine-volume facilities. The Siemens Definition family — including dual-source configurations — anchors the premium end with exceptional speed for cardiac and trauma imaging.
Canon (Toshiba) and Philips
The Canon (Toshiba) Aquilion line spans 16 to 320 slices and is well regarded for image quality and generous tube warranties in its service programs. Philips rounds out the big four with strong dose-management technology and competitive mid- and premium-tier scanners.
Our advice: choose the slice count and condition first, then pick among platforms based on local service coverage and the quotes in front of you. Our medical imaging buyers guides cover platform-specific considerations in more depth.
CT Scanner Price Tiers in 2026: New vs. Refurbished
So how much does a CT scanner cost in 2026? Across the full market, CT scan machines run $90,000 to $900,000 refurbished, while comparable new systems commonly range from roughly $250,000 to well over $2 million. Most facilities land between $90,000 and $400,000, and refurbished pricing typically saves 30–70% versus new.
| Investment Tier | Typical Slice Count | New (Typical Range) | Refurbished (Typical Range) |
|---|---|---|---|
| Entry | 16 Slice | Roughly $250,000–$450,000 | $90,000–$170,000 |
| Intermediate | 32/40 Slice | Roughly $350,000–$600,000 | $130,000–$200,000 |
| Premium | 64 Slice | Roughly $500,000–$1,000,000 | $250,000–$400,000 |
| Ultra-Premium | 128–256+ Slice | Often $1,000,000–$2,000,000+ | $400,000–$900,000 |
These are bounded estimates — actual pricing depends on configuration, tube condition, software licensing, and current market conditions. For a deeper breakdown by model and tier, see our 2026 CT scanner pricing guide.

What Else Drives a CT Scanner Price
Two used CT scanners for sale with the same slice count can differ by tens of thousands of dollars. Here is where that spread comes from.
Tube Condition — the Big Consumable
The X-ray tube is a CT machine’s most expensive wear item, and replacements commonly run well into five figures depending on the model. Tube life is measured in scan seconds or mAs, so always ask for the current tube count and how it compares to expected life. A scanner with a recently replaced tube is genuinely worth more; a system priced attractively but nearing end of tube life may cost more overall within a year or two.
Detector Rows and Hardware Configuration
Within a platform family, detector configuration, gantry rotation speed, table weight capacity, and generator power all affect price. Bariatric-capacity tables and faster rotation typically add cost but expand the patient population you can serve.
Software Licenses
Software is one of the most overlooked line items. Cardiac scoring, coronary CTA packages, dose-reduction (iterative reconstruction) licenses, lung screening, and perfusion tools are often licensed separately. Confirm exactly which licenses transfer with the system — adding them later can be expensive.
Workstation and Accessories
An advanced-visualization workstation, injector, phantoms, and coil-equivalent accessories may or may not be bundled. A complete package can be a better value than a bare gantry-and-table quote that looks cheaper up front.
Step-by-Step: How to Buy a CT Scan Machine
Buying a CT does not need to be complicated. Here is the walkthrough we guide buyers through every week:
- Define your volume and use cases. Estimate daily scan volume and list the studies you must perform — routine body imaging only, or trauma and cardiac too? This single step determines most of what follows.
- Choose your slice count. Match the use cases to the tiers above. Routine work points to 16 slice; ER and cardiac point to 64 slice or higher. Buy the capability you need, not the maximum you can finance.
- Decide new vs. refurbished. If a certified pre-owned system meets the manufacturer’s performance specifications and carries a warranty, the 30–70% savings usually wins. New makes sense mainly when you need the latest ultra-premium technology.
- Plan the site. CT rooms need adequate space, floor loading, power, HVAC, and radiation shielding signed off by a physicist. Start this early — our CT site planning guide covers the requirements room by room.
- Request quotes and compare complete packages. Compare tube condition, included software licenses, warranty terms, and installation scope — not just the sticker price. Ask every vendor the questions in our CT scanner buying FAQ.
- Schedule installation and training. Coordinate rigging, delivery, installation, calibration, and applications training for your technologists. A good vendor handles this end to end, from site planning to shipping, installation and technical servicing.
Timelines vary, but many refurbished CT projects go from signed quote to first patient in a matter of a few months once site work is underway.
Total Cost of Ownership: Beyond the Purchase Price
The purchase price is the headline number, but a smart budget accounts for the full cost of owning a ct machine over its service life. Plan for these categories:
- Service contracts. Comprehensive coverage commonly runs a meaningful annual percentage of the equipment’s value — often in the high single digits to low teens depending on coverage level, response time, and whether the tube is included. Tube-inclusive contracts cost more but remove the largest surprise expense.
- Tube replacement reserves. If your contract excludes the tube, set aside a reserve. Tubes are consumables; how long one lasts depends heavily on scan volume and protocols.
- Electricity and HVAC. CT scan machines draw significant power during scanning and require consistent climate control. Costs vary widely by region and utilization, so estimate with your local rates rather than a generic figure.
- Staffing and accreditation. Certified CT technologists, physicist oversight, and ACR or equivalent accreditation carry recurring costs that belong in the pro forma.
- Insurance and connectivity. Equipment insurance plus PACS/RIS integration and ongoing IT support round out the picture.
As a rough planning posture, many facilities budget total annual operating costs at a moderate percentage of the purchase price. The full CT pricing guide walks through these operating numbers in more detail. Custom quotes always make sense — a generic number rarely reflects what your specific project will cost.
When a Mobile CT Rental Bridges the Gap
Sometimes the right answer is not buying — at least not yet. A mobile CT rental delivers a fully operational scanner in a trailer to your site, keeping revenue and patient care uninterrupted while your long-term plan comes together. Common scenarios:
- Construction or renovation. Your scan room is being rebuilt or shielded, but referrals keep coming.
- Equipment replacement. The gap between de-installing an old CT scan machine and going live on the new one can stretch weeks — a rental bridges it.
- Unexpected downtime. A failed tube or major repair takes your fixed scanner offline longer than your patients can wait.
- Volume testing. A new service line or satellite location wants to prove CT demand before committing capital to a purchase.
Rentals are turnkey — delivery, setup, and service coverage are handled for you — and terms scale from short interim needs to longer engagements. If demand proves out, many facilities transition from rental to a refurbished purchase with a clear picture of exactly how much scanner they need.
How Amber Diagnostics Refurbishes CT Machines
Amber Diagnostics has been buying, refurbishing, and selling medical imaging equipment since 1994. Our goal with every CT is simple: transform imaging equipment back into like-new condition so you can keep your costs down and imaging capabilities high.
Every refurbished CT scan machine we sell goes through a documented process: a multi-point inspection of the gantry, tube, detectors, and table; replacing and repairing worn parts; electrical refurbishment; cosmetic restoration; and final calibration with QA (phantom) testing to confirm the system meets the manufacturer’s performance specifications before it ships.
Because we handle everything from site planning to shipping, installation and technical servicing, you work with one team from the first quote to first patient — with warranty coverage and financing options available. And because Amber also buys equipment, we can structure your upgrade so the sale of your current scanner offsets the new purchase, with our team managing de-installation and logistics.
Frequently Asked Questions
How much does a CT scanner cost in 2026?
Refurbished CT scanners typically cost $90,000 to $900,000 in 2026, and most facilities land between $90,000 and $400,000. Entry-level 16-slice systems commonly run $90,000–$170,000, intermediate 32/40-slice systems $130,000–$200,000, premium 64-slice scanners $250,000–$400,000, and ultra-premium 128- to 256+-slice systems $400,000–$900,000. New systems commonly cost roughly two to three times more at each tier, which is why refurbished purchases typically save 30–70%. Final pricing depends on tube condition, software licenses, and configuration, so a custom quote is the only reliable number for budgeting.
What is the difference between a 16-slice and a 64-slice CT machine?
Slice count is the number of image rows the scanner captures per rotation. A 16-slice CT machine handles routine head, chest, abdomen, spine, and orthopedic imaging very well and costs significantly less. A 64-slice system scans faster, produces thinner slices, and — most importantly — supports coronary CT angiography and demanding ER protocols like stroke and trauma workups. If your caseload is routine outpatient imaging, 16 slices is usually enough; if you serve an emergency department or cardiology referrals, 64 slices is the practical baseline.
Is a used CT scanner for sale a safe investment?
Yes — provided it comes from a reputable refurbisher. A properly refurbished CT goes through multi-point inspection, replacement of worn parts, electrical refurbishment, and final calibration with QA phantom testing to confirm it meets the manufacturer’s performance specifications, and it should ship with a warranty. The keys are verifying tube condition (ask for tube usage counts), confirming which software licenses transfer, and buying from a vendor with a real service capability. Done right, a used CT scanner delivers years of reliable clinical service at 30–70% below the cost of new.
How long does a CT scan machine last?
A well-maintained CT platform commonly serves 10 years or more, and refurbished systems routinely deliver many years of additional clinical life. The tube is the main consumable — expect one or more tube replacements over the scanner’s life depending on volume. Parts availability matters more than age alone: high-volume platforms like the GE LightSpeed family and Siemens Emotion series remain serviceable for a long time because parts and engineers who know them are plentiful. A service contract and disciplined preventive maintenance are the biggest factors in reaching the long end of the lifespan range.
What do I need to install a CT scanner at my facility?
Plan for four things: space, structure, power, and shielding. You need a scan room large enough for the gantry and table plus a control room, floors rated for the system’s weight, dedicated electrical service per the manufacturer’s specifications, and lead shielding designed and signed off by a qualified physicist to meet state radiation regulations. HVAC capacity for consistent temperature and humidity matters too. Site work often runs in parallel with equipment refurbishment, and starting early keeps the project on schedule.
