GE Healthcare today unveiled Revolution Ascendvi with Effortless
Workflow, offering clinicians a collection of artificial
intelligence technologies that automate and simplify time-consuming
tasks to increase operational efficiency and free up time for
clinicians to deliver more personalized care to more patients. The
computed tomography (CT) system’s new 75 cm wide-gantry, 40 mm
detector coverage, and lower table position are designed to
accommodate high body mass index (BMI) patients as well as trauma
cases that would otherwise be too delicate to maneuver in a smaller
size gantry.
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 Timothy P. Szczykutowicz, Ph.D., director of
clinical operations and the CT Protocol Project at the University
of Wisconsin School of Medicine and Public Health as well as author
of The CT Handbook: Optimizing Protocols for Today's Feature-Rich
Scanners. “Within a typical 10–30-minute CT exam, the scan itself
only takes a few minutes and the remainder of the time is dedicated
to patient prep – including positioning the patient and identifying
the correct protocols and settings, plus image reconstruction and
report time. Historically, these have been manual processes,
putting them at risk of human error; however, AI offers new
opportunities to automate workflows and expedite exams with the
same or better results.”
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 and 21% 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
Gladys Farias, Imaging Services Manager at Baptist Health in Miami,
Florida – one of the first installation sites for Revolution
Ascend. “Not only do the system’s intelligent solutions help us
expedite exams, but they also enable us to deliver a more
comfortable and personalized experience for each patient.
Technologists love it for its simplicity. Clinicians love it for
its results. And patients love it for its fast exams and
comfort.”
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
22%xiv to provide patients additional space for a more comfortable
CT scanning experience. This new wider bore design represents the
widest gantry aperture at the shortest geometry design in its
class.
“We designed Revolution Ascend with accessibility in mind,”
explains Jean-Luc Procaccini, President & CEO, Molecular
Imaging & Computed Tomography, GE Healthcare. “Not only does
the system’s hardware help accommodate more patients with various
physical limitations, but its cutting-edge AI also helps expedite
exams so healthcare system schedules can accommodate additional
patient scans. Altogether, Revolution Ascend with Effortless
Workflow helps empower clinicians to reach the right diagnosis as
efficiently and precisely as possible for more patients.”
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. iii TrueFidelity CT Images on

different exam descriptions, collected from 4 different medical
evaluation site. x The data was based on comparison between GE’s
legacy products (16ch and 64ch scanner) and Revolution Ascend in

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, The
Phantom Laboratory), using model observer method. 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
The Phantom Laboratory). DLIR and ASiR‐V reconstructions were
performed using the same raw data. xiv Patient area defined by
circular area between the top of the gantry bore and the center of
the tabletop surface at lowest cradle position.
