1. In clinical practice, the use of ASiR, ASiR-V 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.

Benefits

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 Metal Artifact Reduction (MAR). 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)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.

Technology

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.

The Gemstone Detector
Gemstone™ is the essential innovation that drives the high definition breakthrough. Comprised of our proprietary CT scintillator material, its exclusive garnet structure enables high-definition imaging during sub-second scanning and fast kV switching. Gemstone’s recovery time is four times faster than comparable detectors and its primary speed is 100 times faster than competitors.

Gemstone Spectral Imaging (GSI)
GSI’s unique and fast-kV switching technology offers 0.25 msec temporal sampling of 140 kV and 80 kV at full 50 cm field of view (FOV) with near perfect anatomical registration – even at dose levels the same as single standard acquisition. This acquisition allows for reconstruction and viewing of monochromatic images from 40 keV to 140 keV.

Iterative Reconstruction
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.

ASiR-V™ is offered as an option and is designed to reduce noise levels, improve low contrast detectability and reduce dose by up to 82% in routine imaging for all exams and all patients1,2.

Veo™ is offered as an option and is the ultimate advancement in CT image reconstruction technology. It’s also the world’s first model-based iterative reconstruction product enabling imaging less than 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 Data AcquisitionSystem
Volara™ DAS technology reduces electronic noise for outstanding image quality in both high and low signal areas of the anatomy. It’s also an integral part of the system’s improved spatial resolution across the entire field of view and delivers 2.5 times more views per rotation to improve x and y axis resolution and reduce artifacts.

Tube
The Performix™ HD Tube enables the visualization of more detail with increased data sampling, ultra-fast kV switching and a maximum mA of up to 570 mA on the small focal spot and 835 mA on the large focal spot.

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.

2. Low contrast detectability (LCD), image noise, spatial resolution and artifacts were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625 mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method.

Veo

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 Revolution™ 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.

Discovery CT750 HD FREEdom Edition- Veo

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.
