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.
Introducing Revolution Frontier. From Innovation to Outcomes... Everyday.
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 Performix™ 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 0.25 ms 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,2
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
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

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,3 Freeze for coronary artery CTA and
reduce all-round dose with our next-generation iterative
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

1. Revolution Frontier is not CE marked. Not available for sale in all regions.
2. The use of ASiR-V may reduce CT patient dose depending on the clinical task, patient size, anatomical location and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task.
