For nearly 50 years, CT has proven to be a vital imaging tool used by clinicians to detect cancer, stroke, heart conditions, and other diseases. However, as CT procedure volume grows – reaching an all-time highvii ahead of the COVID-19 pandemic – so too does the need to optimize CT protocols and expand patient positioning options to help expedite exams and accommodate more patients.
“The most time-consuming part of the CT experience isn’t the scan itself, but the steps that fall outside the scan,” explains industry expert
Revolution Ascend helps address these challenges with GE Healthcare’s Effortless Workflow, a new suite of AI solutions that personalize scans accurately and automatically for each patient while requiring significantly less effort from the CT technologist. It starts with the technologist using the system’s attached bar code reader to scan the patient’s chart or tag and personalize each exam: automatically pulling up the patient’s information and suggesting relevant protocols. With one click, the CT technologist can then initiate Auto Positioning, which uses real-time depth-sensing technology to generate a 3D model of the patient’s body and a deep learning algorithm to determine the correct table elevation and cradle movements to align the center of the scan range with the isocenter of the bore. Once the patient is ready to be scanned, intelligent tools embedded in the new Clarity Operator Environment provide optimal scan range settings, dose, and image quality for each individual, helping to deliver greater efficiency and more personalized medicine across clinical care areas.
Altogether, Effortless Workflow’s AI-based features streamline the entire CT process by automatically:
-
Positioning patients with
94% auto centering accuracy within +/- 2 cmviii; -
Suggesting protocols with
90% accuracyix; -
Automating and expediting workflows with a
66% reduction in clicksi; -
Saving
56% of time for scan settings and21% for the entire examx; -
Reducing up to
91% image noise at the same dosexi, xii; and - Improving spatial resolution up to 2x at the same image qualityxi, xii.
“Having Revolution Ascend is like having an extra set of hands – which are much needed in today’s healthcare environment,” says
Revolution Ascend also uses a dedicated deep neural network to generate TrueFidelity CT Imagesiii to help improve reading confidence in a wide range of clinical applications – such as head, whole body, and cardiovascular, for patients of all ages. Compared to even the most advanced iterative reconstruction technology, TrueFidelity CT Images can elevate every image to a powerful first impression with impressive image quality performancexiii, and preferred image sharpnessv and noise textureiv – all without compromising the low dose levels to which clinicians have grown accustomed.
Furthermore, Revolution Ascend’s 75 cm wide-gantry design with a lower table position increases the patient area inside the bore by
“We designed Revolution Ascend with accessibility in mind,” explains
Revolution Ascend’s Effortless Workflow, as well as additional advanced applications, are offered as an upgrade to existing GE Healthcare CT systems or by acquiring Smart Subscription – an Edison service – which provides access to the latest CT device software across a hospital system’s entire CT fleet. This common access to GE Healthcare’s digital ecosystem of applications helps increase staff efficiency, reduces training, and improves satisfaction by ensuring there is one set of capabilities for healthcare workers to learn, operate and read.

i The required clicks are defined as clicks required to execute a scan from selecting a new patient til 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.
ii The data was based on comparison between GE’s legacy products (16ch and 64ch 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.

xi Image quality as defined by low contrast detectability.
xii 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,
xiii Image quality comparisons between DLIR and ASiR-V, were evaluated by phantom tests of MTF, SSP, axial NPS, standard deviation of image noise, CT Number accuracy, CNR, and artefact analysis. Additionally, LCD was demonstrated in phantom testing using a model observer with the head and body MITA CT IQ Phantoms (CT191, CT189
