Revolution Ascend

A New Standard for CT


Revolution Ascend utilizes AI technology to automatically suggest protocols and position the patient.


Clarity Operator Environment can consistently provide the optimal scan range settings, dose and image quality for each patient.


Revolution Ascend lets you choose the right image review and analysis package for your system

Manage increased CT procedure volume with faster workflow and clearer images.

We have redefined the entire CT experience with Revolution™ Ascend, a 75 cm wide-bore CT system that makes the CT process faster, more intuitive and more approachable, while also providing the image quality you expect. We use an AI-based workflow solution, a smart user interface, cutting-edge technology and access to Smart Subscription to simplify, streamline and automate the entire CT experience.

Multi-faceted in multiple applications

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

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 Revolution Ascend. As a result, Revolution Ascend 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.

Revolutionizing CT from referral to report

We seek to boost operational efficiency with the goal of making your imaging workflow feel like second nature. We studied the entire CT workflow and created solutions to simplify the process. These solutions are the core of our Effortless Workflow model.

Automatically intuitive

With the introduction of Revolution Ascend, we are moving to standardize functions by embedding the same user interface (UI) as our top-of-the-line CT system. The UI features the new Clarity Operator Environment, designed with your everyday needs in mind with features like Smart Plan for an intelligent anatomy recognition and localizer setting. Additionally, Auto Prescription adjusts scan setup by recommending scan parameters specific to the patient, enabling desired image quality and dose performance across scans, irrespective of your expertise level.

A futuristic take on classic image reconstruction

Revolution Ascend includes TrueFidelity images generated by our Deep Learning Image Reconstruction engine. It provides deep detail, remarkable contrast, texture and image clarity without compromise. TrueFidelity images are created using artificial intelligence to combine the low dose of iterative reconstruction with image appearance similar to filtered back projection.

A CT for everybody

Revolution Ascend pairs a new 75-centimeter-wide gantry design with a lower table position to increase the patient area1 inside the bore by 22 percent compared to previous generation GE CT scanners. This increase provides more space to patients for a more comfortable CT scanning experience. With this new wider bore design, Revolution Ascend provides the widest gantry aperture at the shortest geometry design of its class1, making CT available to large patients as well as trauma cases that would be too delicate to maneuver into a smaller gantry.

A CT that keeps getting better

CT application development never stops, yet traditional purchase models make it difficult for you to keep up. Smart Subscription, our new subscription-based service for CT applications, automatically keeps all of your systems up to date. For one annual fee per device, you can be sure your CT fleet is always equipped with the latest software capabilities, saving you time and money.

Additional Revolution Ascend Features


More room inside the gantry for better patient access and comfort.2


Reduction in clicks for faster and more automatic workflow.3


Image noise reduction by ASiR-V compared to FBP at the same dose, depending upon the scan technique and reconstruction parameters.4
  1. 1. Referred class is identified as CT scanners in the industry that have 38.4-40 mm detector coverage with maximum generator power which has a capability from 55 kW to 82 kW, as of July 2021.
  2. 2. Patient area defined by circular area between the top of the gantry bore and the center of the tabletop surface at lowest cradle position.
  3. 3. 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.
  4. 4. 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. Low Contrast Detectability (LCD), Image Noise, Spatial Resolution and Artifact 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.
