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:
Confidence boosting clarity
Spatial and temporal resolution, signal-to-noise ratio, low-contrast detectability and artifact reduction are all fundamental to CT image quality. Revolution HD offers a true diagnostic breakthrough with best-in-class spatial resolution of 0.23 mm across the full two meter scan length1, 29 msec of temporal resolution2 and Smart MAR is designed to reveal anatomic details obscured by metal artifacts, helping clinicians diagnose disease with greater confidence.
Low dose made possible by iterative reconstruction
Typically, lowering dose has increased noise and image artifacts, creating a difficult balance between higher image quality and lower dose. To help you overcome these challenges and keep you on the cutting edge, Revolution HD offers three advanced iterative reconstruction technologies, ASiR-V (option)3.
Gemstone™ Spectral Imaging (GSI) helps you make a more confident diagnosis
GSI enables you to take CT beyond classical anatomical assessment to quantitative tissue characterization and advanced functional imaging. More than 15 applications are now in routine use including oncology, cardiology, neurology, spine, urology and musculoskeletal. To learn more about GSI clinical benefits, visit the GSI image gallery and the GSI education center.
Best-in-class cardiac CT
Revolution HD has best-in-class cardiac CT spatial resolution. At 18.2 lp/cm4, 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 msec2.
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.

3. In clinical practice, 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.
