Top CT Scanners [Manufacturers, Models, and Slice Counts]

Few things are more frustrating than punching in your search terms in Google and not finding what you’re looking for. When it comes to CT scanners, the search results landscape can feel frenetic, with bits and pieces of info from different sites but no cohesive, one-stop-shop for all your CT questions.

There is a buffet of refurbished CT scanner options to choose from. To be an educated buyer, you’re wanting to narrow in on specifics, like manufacturer, model, slice count, and more. The good news is, you’ve come to the right place. This guide will provide you all the necessary information you’re looking for and plenty of ways you can continue your research. If you’re looking for more information on CT pricing, check out ourguide for that as well.

Who are the top CT manufacturers and models?

The top manufacturers in the CT space are Siemens, GE, Toshiba, and Philips – all of which are manufacturers that Block Imaging carries. You’ll notice that Siemens and GE are tied for the number one spot.

Tie for #1: Siemens

Pros: Siemens has better innovation and a wider array of products.

Cons: Siemens often has higher service costs and has proprietary tubes that keep service costs higher.

Top Model(s): Flash and Force (but also the most expensive to service) especially if your studies are mostly cardiac related.

Definition Edge and Definition AS Series are great 64-slice and 128-slice options for reliability for high volumes. These models can be air or water cooled.

The Perspective 64/128 are air cooled, a practical option for smaller footprint and moderate patient volume.

The cost of tubes are the biggest draw backs for Siemens 16-slice scanners. Perspective 16’s, Emotion 16’s and Scopes are all good systems, but the tube costs may catch some facilities off guard.

Tie for #1: GE

Pros: GE’s typically have the lower service costs, they are less locked down for service, there is a higher supply of used parts, and they are more likely to have secondary tube manufacturers (for additional savings). Also, they’re air cooled, so you never need a chiller and they typically have a smaller footprints than they’re competitors’ comparable models.

Cons: GE has lacked innovation at the high end until recently. For example, each model of the 16-slice is built off the one before (Lightspeed, Brightspeed and Optima 540 often all have the same type of tube). This means the platforms are familiar to techs, and repairs are similar to engineers, but if you’re looking for advanced features you may be disappointed. Their newer version of 16-slices (Brivo/ACT) have lower end features, less power and smaller tube capacity. And they never got FDA approved.

Top model(s): GE Revolution 256 and Maxima are the latest and greatest. On paper they’re robust and impressive, however, early on there were a lot of delivery issues and extended downtimes. Very expensive to purchase (and service), so unless you have an infinite budget, may not be your best bet.

The Optima 660/Revolution EVO are practical solutions for most facilities. They are mostly 64/128 slices; newer versions can come with advanced features like Metal Artifact Reduction. This likely to be the most popular system on the secondhand market over the next 10 years.

The LightSpeed VCT 64 is still a very practical solution for a 64 slice. These are tried and true as they’ve been around for 20 years, nothing fancy with them, but a well-known reliable option and probably the best for a entry level of the 64 slice world.

Optima 540/BrightSpeed Pro: Most popular higher end 16 Slice CT Scanner. Both will have the 6.3 MHU tubes, great for moderate patient loads, that don’t do cardiac studies.

Optima 520/BrightSpeed Select: Most popular 16 for someone looking for low cost of service. Tube is a 3.5 MHU, low cost to replace, it has a lower draw on power if that is a limiting factor.

#2: Toshiba

Pros: Toshiba users report great image quality and user-friendly platform. The systems are air cooled, so no chiller is required.

Cons: These systems have a lot of service calls and downtime and they are difficult to service.

Top model(s): The Aquilion ONE (160/320/640 slices) is popular, as is the Aquilion Prime 80/160.

The Aquilion series all use a version of the Megacool, 750D tube, which has a good track record. There are also aftermarket options for other tube options.

#3: Philips

Pros: Good options for cardiac studies. The MRC tube is the most reliable tube made. While others last 1-3 years, the MRC tube can last 10 years or more.

Cons: These systems have been known for being difficult to service. There are not as many parts available and are often locked down intentionally by the OEM.

Top model(s): Ingenuity/iCT (64/128/256) is a leading model for cardiac studies. Most common model was their Brilliance 64, but they haven’t been manufactured in 15 years.

Slice Count: what is it and what one do I need?

Slice refers to the number of rows of detectors in the z-axis of a CT scanner. As shown in the below infographic, common range counts range from 16, 32, 4, and 128. You will also find counts from 256, 320, and 640 in newer models.

As slice counts increase, so do the price, up-front costs, and service costs. For typical price ranges on CT scanners and slice counts, check out our 2024 CT Scanner Price Guide.
