Your patients get a CT because they need answers, quickly. But a challenge with conventional CT today is that doctors see the anatomy, but may be unable to characterize disease due to lack of fine detail or lack of tissue composition such as calcium, iodine, blood or fat. This can often lead to additional follow-up tests to make the diagnosis. As a result, CT needs to evolve: from anatomy to function, from structure to chemical composition, and from high sensitivity (detection) to high specificity (disease characterization).
Our Revolution™ brand of CT systems is built from our passion to provide you with extraordinary technologies that will allow you to reach the right diagnosis, effortlessly. To push the boundaries of what you expect from your CT, enabling you to see beyond anatomy and explore new areas of care.
Our Revolution family of CT systems is known for its breakthrough imaging technology. Revolution Frontier was designed to take this technology to the next level for your high-performance clinical needs.
Its all-new imaging chain features the powerful PerformixTM HD Plus X-ray tube, which significantly reduces the wear that is typical with conventional ball bearing technology. The result is a shorter tube warm-up time between patients as well as two times longer tube life.
It also includes our GemstoneTM Clarity detector modules. Built with the proven Gemstone material known for its high primary speed and low afterglow, the miniaturized design of each detector module shortens the distance information has to travel. The result is a significant reduction in electronic noise, impressive spatial resolution and spectral imaging capabilities. For the most challenging cases, you can easily implement High Definition mode to further improve spatial resolution to 0.23 mm.
As a provider in a high-performing clinical environment, you constantly look for opportunities to adopt the latest in imaging technologies, like spectral imaging. However, you can't afford to adopt this technology if it has limited utility or doesn't fit into the processes you already have in place. We addressed this challenge with GSI Pro.
GSI is our proven spectral imaging application that uses the Gemstone detector and rapid kV switching to acquire dual energy samples from a single source. By rapidly switching between two different kV energies at a rate of up to 0.25ms with sub-millimeter Z-axis registration, its temporal registration is over 165 times faster than other dual energy technologies. And the advantage of its single source architecture is the ability to generate material decomposition images over the full 50 cm field of view.
We addressed and improved the GSI experience to seamlessly integrate with AW applications and to significantly reduce reconstruction times. It's a breakthrough in spectral CT technology that effortlessly processes gigabytes of data at a time, making the clinical benefits of GSI routinely accessible.
The clinical benefits of GSI Pro include up to a 50 percent improvement in beam-hardening artifact due to bone, metal and other high-contrast materials such as iodine. It also has the ability to deliver non-contrast-like images by subtracting detected iodine from an image. By incorporating the latest in iterative reconstruction technology, ASiR-VTM,1 enables dose neutrality, lower image noise and improved low contrast detectability for patients of any size.
With over 300 publications on GSI, example findings* by the academic community include: liver lesion detection by 17% and kidney lesion characterization by 12%, reducing the need for unnecessary follow-upsa,b, reduce contrast by at least 50%, benefitting patients with renal functionc,d,e and 6 times reduction in non-interpretable scans with GSI MARf,g. (see GSI Infographic)

Revolution Frontier was designed around the principle that no two examinations are ever the same. Choice is what allows you to adapt your CT to your patient and not the other way around.
With Revolution Frontier, we have made sure that you can address individual clinical needs, by moving seamlessly from one scan mode to the next. You can image with a stunning 0.23 mm spatial resolution
and then switch to rapid kV switching for full 50 cm FOV spectral imaging of the entire body. Choose up to six times reduction in motion artifact using SnapShotTM,2 Freeze for coronary artery CTA and reduce all-round dose with our next-generation iterative reconstruction, ASiR-V.
This level of clinical versatility is supported by key service solutions to keep your CT up and running. Reducing the downtime needed to replace your x-ray tube is just one way we can help. As an original
equipment manufacturer, we know more about our systems than anyone else. We are proud to offer a complete package of predictive and proactive service solutions to ensure your system stays at peak performance.
