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 length2, 29 msec of temporal resolution3 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 (standard), ASiR-V (option) and Veo (option)1.
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 msec3.
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.
Modern imaging intelligence
Revolution HD features Smart Technologies, a suite of intelligent CT tools designed to help you achieve your imaging goals with improved efficiency and expanded applications, all while delivering diagnostic confidence with lower levels of radiation.
Smart Dose with kV Assist provides automated kV and mA recommendations allowing users to tailor protocols to each patient, clinical indication and each scan area. Smart Cardiac with SnapShot Assist helps you optimize cardiac scanning for individual patients based on their specific parameters. Smart Spectral with GSI Assist helps you optimize GSI protocols to your patient and clinical needs.

Deliver better care at the right dose
More than ever you are being asked to focus on lowering and managing radiation dose for every patient. Governments are enacting new laws that require everything from including the dose in interpretive reports to establishing committees and processes to manage protocols. Accrediting bodies are proposing and adopting new standards that require changes to credentialing and setting up regular protocol reviews. Professional organizations are establishing new diagnostic reference levels and guidelines for protocol management teams. All focused on ensuring that the lowest reasonable dose is used for every patient, every clinical situation, every time.
With this in mind, GE creates CT technologies to help you meet your challenges and goals today and tomorrow.
Imaging under 1 mSv with profound clarity1
Veo™, offered as an option on RevolutionTM HD, makes it possible for you to change the rules of CT imaging, acquiring high-quality images at doses that were previously unthinkable. Patients will benefit from your ability to use Veo to adapt both image quality and dose reduction for each specific clinical task. Using Veo you may be able to:
- Improve resolution at lower doses to evaluate patients with intravascular stents, suspected joint injuries or diseases and other clinical applications where seeing finer details is important.
- Reduce artifacts like beam-hardening from bones, enabling you to see underlying structures more clearly in brain and other exams.
- Reduce doses to less than 1 mSv for many of your most sensitive patients including follow-up exams, lung imaging and for pediatric patients.
Built to work the way you do
Your days are busy. You don't have extra time to spend after each exam setting up additional reconstructions and reformats. Which is why we've built the capabilities you'll need right into the protocols. With Veo, you can prescribe and save thick slice reconstructions and coronal and sagittal reformats in each protocol.
1. In clinical practice, the use of 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. In clinical practice, the actual level of LCD and spatial resolution and low signal artifact improvement may vary. Consult with a radiologist and a physicist.
