You and your patients continue to demand lower dose, but not at the expense of diagnostic image quality. Revolution* HD delivers on both imperatives with a number of clinical benefits:
Low dose made possible by ASiR* and Veo*
Typically, lowering dose has increased noise and image artifacts, creating a difficult balance between higher image quality and lower dose. ASiR, which comes standard on Revolution HD, is the industry’s most-used iterative reconstruction technology with over 47 million patients benefiting from its use to date.
In addition, Revolution HD offers Veo as an option, the ultimate advancement in CT image reconstruction technology and the world’s first model-based iterative reconstruction product enabling imaging under 1 mSv with profound clarity. With Veo, lower noise and higher resolution can be achieved within a single image. At the same time, significant dose reduction capabilities are now available, opening up new possibilities for challenging cases and sensitive patients. This breakthrough is changing the way physicians use CT imaging, delivering a combination of high-performance images and low dose that was previously unthinkable1.
The highest resolution in cardiac CT
Revolution HD has best-in-class cardiac CT spatial resolution. At 18.2 lp/cm2, the system provides up to 66% greater spatial resolution than comparable systems. Offered as an option, SnapShot* Freeze is designed to reduce blurring artifacts due to motion in coronary vessels that cannot be addressed by gantry speed alone. Providing up to 6x improvement while maintaining high spatial resolution, the reduction in motion artifacts is equivalent to a 0.058s equivalent gantry rotation speed with effective temporal resolution of 29 msec3.
Greater coverage makes advanced techniques possible
Revolution HD has features that enable the performance of advanced diagnostic techniques. VolumeShuttle is a feature that offers acquisition coverage of 80 mm. As a result, clinicians can perform CT perfusion in a single scan, with a single contrast injection. Volume Helical Shuttle is a continuous bi-directional scan mode that extends z-coverage and improves temporal sampling. The result is more than 300 mm of high-resolution volume coverage, equivalent to a 500-slice image, and the ability to perform 4D-CTA studies.
Focus less on the system and more on your patients
The Xtream display prominently shows the patient name, making exams more personal. It also includes
a number of educational videos that explain CT procedures or can be used as a distraction
technique for younger patients. In addition, with one-stop ED mode, you can select and confirm patient, protocol and scan settings at the gantry.
Upgrade to Gemstone* Spectral Imaging (GSI), the first quantitative dual-energy technology on the market
GSI is a unique dual energy technique that uses fast kV switching to acquire and generate material density data, enabling clinicians to identify the chemical composition of body materials and aids in the characterization of tissue and materials. Learn more about Revolution GSI.
1. In clinical practice, the use of ASiR and Veo 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.
