Whether you need to boost image definition or add spectral detail, Revolution FrontierTM
will advance the clinical value of CT.
Explore new areas of care
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 RevolutionTM 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.
Outcomes
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 least50%, benefitting patients with renal functionc,d,e and 6 times reduction in non-interpretable scans with GSI MARf,g. (see GSI Infographic)
*The example findings cited are limited to the referenced studies only and may not be broadly applicable to your clinical practice.
