A Revolution in CT efficiency

Introducing the Revolution™ Ascend platform- our latest CT offering that is designed for efficiency to match your imaging demands. Whether you require a highly efficient system with 20mm of coverage for routine scanning, or a more advanced system with 40mm of coverage that improves low contrast detectability, you can choose exactly what you need. Since the Revolution Ascend platform is scalable, you can decide which system is right for you today and easily upgrade when you need it in the future.

Multi-faceted in multiple applications

The Revolution Ascend platform has features for most environments including routine, cardiac, large patient, ER, and interventional.

Enhance what matters

True Enhance DL¹ is designed to increase contrast resolution for confident diagnosis- especially for challenging oncology cases or pulmonary embolism evaluation. True Enhance DL uses a dedicated Deep Neural Network (DNN) to generate deep learning-based monochromatic-like images from single-energy X-ray. This technology is engineered to provide you with a simple workflow and incredible image quality without a radiation penalty.

Deep learning for a deeper understanding

TrueFidelity DL⁵ is our exceptional image reconstruction technology that uses a Deep Neural Network (DNN) to generate high-definition, low-noise CT images. TrueFidelity DL produces images with exceptional sharpness, low-contrast performance, and your preferred noise texture⁸, at the same dose⁵.

Simplified scanning from start to finish

Available on all Revolution Ascend platform configurations, Effortless Workflow intelligently automates your CT workflow from pre-scan protocoling to post-scan processing. It uses AI-based features to help transform the entire CT experience and helps maximize efficiency, accuracy, clarity and consistency. This enables technologists to automatically and accurately personalize scans for each patient with significantly less effort. The end result is a beautiful CT image acquired in less time.

Scale as you need to

Revolution Ascend platforms’ carefully optimized configurations allow you to invest in the clinical capabilities you need today and allow for your CT to grow with you. Revolution Ascend Select can be upgraded to Plus or Elite. And Revolution Ascend Plus can be upgraded to Elite. All of the configurations are paired with Effortless Workflow and Smart Subscription for a remarkably efficient CT experience.

Revolution Ascend platform configuration

Revolution Ascend Select

High performance for routine and basic coronary analysis for now and later.

Revolution Ascend Plus

With a faster workflow from referral to report.

Revolution Ascend Elite

Remarkable detectability and diagnosis.

Redefining clinical performance

The most time-consuming part of the CT experience isn’t the scan itself, but the steps that fall outside the scan such as patient prep and recon to report time. We analyzed all of the pre-scan and post-scan steps in the CT experience and incorporated our key findings into the design of the Revolution Ascend platform.* As a result, the Revolution Ascend platform solves common concerns like the ability to efficiently accommodate high BMI patients and interventional procedures. It also enables easy two button scanning for all imaging.

A CT for everybody

The Revolution Ascend platform pairs a 75-centimeter-wide gantry design with a lower table position to increase the patient area³ inside the bore by 22 percent compared to previous generation CT scanners. This increase provides more space to patients for a more comfortable CT scanning experience. With this wider bore design, the Revolution Ascend Platform provides the widest gantry aperture at the shortest geometry design of its class², making CT available to large patients as well as trauma cases that would be too delicate to maneuver into a smaller gantry.

Access to the latest CT capabilities

The Revolution Ascend platform offers Smart Subscription, our industry’s first subscription-based service for CT. This helps you keep your computing platform, clinical software applications, and workflow innovations up to date across your entire fleet.

  1. 1. True Enhance DL is 510(k) pending in the U.S. FDA. Not available for sale in the United States.
  2. 2. Referred class is identified as CT scanners in the industry that have 38.4-40mm detector coverage with maximum generator power which has a capability from 55 kW to 82 kW, as of July 2021.
  3. 3. Patient area defined by circular area between the top of the gantry bore and the center of the tabletop surface at lowest cradle position.
  4. 4. The required clicks are defined as clicks required to execute a scan from selecting a new patient until start scan. All associated clicks for and in clinical practice, number of the required clicks may vary depending on the circumstances, including but not limited to, the clinical task, exam type, clinical practice, and image reconstruction technique.
  5. 5. 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 physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. Low Contrast Detectability (LCD), Image Noise, Spacial Resolution and Artifact were assessed using reference factory protocols comparing ASiR-V and FBP. The LCD measured in 0.625mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using model observer method. AI enabled.
  6. 6. The data was based on comparison between GE’s legacy products (16 ch and 64 ch scanner) and Revolution Ascend in the three institutions using a pilot product and selected routine head and body. The data set of this comparison was 838 exams for legacy products and 1387 exams for Revolution Ascend. The time saving value may not be effective for all institutions depending on the clinical practice. Defined the scan setting time is from “Open new patient” to “Confirm setting for Scout”.
  7. 7. The data was based on comparison between GE’s legacy products (16 ch and 64 ch scanner) and Revolution Ascend in the three institutions using a pilot product and selected routine head and body. The data set of this comparison was 838 exams for legacy products and 1387 exams for Revolution Ascend. The time saving value may not be effective for all institutions depending on the clinical practice. Definition of entire exam time is from “Open new patient” to “Last primary recon completed” for Revolution Ascend and “Close exam” for legacy products.
  8. 8. As demonstrated in a clinical evaluation consisting of 40 cases and 6 physicians, where each case was reconstructed with both DLIR and ASiR-V and evaluated by 3 of the physicians. In 92% of the reads, DLIR’s noise texture was rated better than ASiR-V’s. This rating was based on each individual reader’s preference.
  9. 9. Image quality comparisons were evaluated by phantom tests of MTF, SSP, axial NPS, standard deviation of image noise, CT Number accuracy, CNR, and artifact analysis. Additionally, LCD was demonstrated in phantom testing using a model observer with the head and body MITA CT IQ Phantoms (CT191, CT189 The Phantom Laboratory). DLIR-H and ASiR-V reconstructions were performed using the same raw data.
