Siemens ACUSON Sequoia

The Siemens ACUSON Sequoia is a fully featured
Ultra-Premium ultrasound system delivering clinical
excellence across ultrasound specialties.
The Crown Edition expands the platform with innovative imaging,
exclusive technologies, and specialty transducers designed to
improve diagnostic accuracy in nearly every clinical use case.
Built to intelligently respond to patient- and user-specific needs,
it reduces variability across patients, systems, and users,
helping to improve clinical, operational,
and financial outcomes while enabling personalized precision medicine.

Powered by BioAcoustic imaging technology
The ACUSON Sequoia is powered by BioAcoustic imaging technology,
which maximizes the sensitivity and depth of scans for deeper,
clearer images and greater diagnostic confidence.
Next-generation hardware and InTune transducer technology work together
to overcome the variability that has historically limited ultrasound’s potential.

Next-generation hardware with the ability to store up to 6x more energy.
InTune transducer technology delivering up to 2x deeper penetration.
InTune Pulser transmitting and receiving signals with up to 10x higher acoustic fidelity.
InFocus imaging technology providing up to 3x more sensitivity.

Intelligent Imaging
InFocus Imaging Technology: eliminates the need for conventional focal zones, creating a
fully focused image at all depths with faster frame rates. It uses synthesized,
retrospectively focused transmit beams and massive overlapping multibeam groups,
with secondary beamforming and physics-based delay technologies plus
amplitude corrections to sharpen the image and improve spatial resolution beyond
what is typical for a given transducer frequency.
AutoFlash Color Suppression Technology: reduces color flash artifacts without
user interaction for improved color sensitivity and performance,
even when a patient is actively breathing.
Slow Flow Color Doppler: uses smart filters and adaptive signal enhancement
to image smaller, low-flow vessels further into tissue with reduced flash artifact.
Speed of Sound Adjustment: improves contrast and detail resolution
for the most accurate representation of different tissue types.
Single Crystal Technology for highly detailed resolution.
Dynamic MultiHertz and TEQ imaging technologies.

Automation and AI-enabled tools
Auto Doppler: reduces the number of exam keystrokes by more than 25%.
Auto Spectral: automatically optimizes Doppler for gain, baseline, scale,
and wall filter, keeping operator adjustments to a minimum.
AutoCalcs (eSieCalcs): delivers comprehensive measurements of
complex lesions using a machine-learning algorithm that instantly calculates length,
AP, and circumference, improving measurement efficiency and reducing variability.
1-touch registration: machine-learning technology automatically selects the
correct transducer and exam type for a seamless workflow.
Gesture-detecting transducers: tap anywhere on the transducer to
quickly activate and start scanning via unique sensor technology.

Expanded Insights: advanced applications
Built from the ground up with dedicated hardware for
exceptional performance in contrast-enhanced ultrasound (CEUS)
and elastography, the system offers a comprehensive advanced-applications
toolbox from tissue quantification and characterization through to
interventional procedures.

Ultrasound Derived Fat Fraction (UDFF): noninvasive assessment of
hepatic steatosis (NAFLD), setting a new benchmark in liver-fat quantification
with a simple, clear cutoff value of greater than 5%.
Available on three abdominal transducers (5C1, 9C2, and DAX) for
nearly any patient body habitus.
Next-Generation Breast 2D-SWE: next-gen breast elastography to
characterize lesions as benign or malignant with greater sensitivity in
detecting and visualizing malignant breast lesions.
Auto pSWE (point shear-wave elastography): rapidly reduces liver elastography acquisition
time by up to 75%, acquiring up to 15 valid pSWE measurements in less than 5 seconds.
CEUS Imaging with Cadence Pulse Sequencing (CPS): contrast-enhanced ultrasound
with twice the sensitivity of previous systems for improved diagnostic confidence.
syngo Velocity Vector Imaging (VVI): semi-automated assessment of myocardial motion
and mechanics with Global Longitudinal Strain (GLS), Global Circumferential Strain (GCS),
and Global Radial Strain (GRS).
Fusion Imaging: combines imaging modalities such as CT and ultrasound for
improved diagnostic confidence.
Modality Compare: import and view previous patient studies alongside
real-time ultrasound images to pinpoint regions of interest and improve procedural efficiency.
3D/4D Volume Imaging: visualize anatomy in new dimensions.
Cardiac Imaging: exceptional tissue definition, valvular detail, and blood-flow visualization.
Virtual Touch elastography technologies.

InTune transducers
Next-generation transducers are specifically designed to produce optimal acoustics for each clinical use case, with acoustic matching optimized through advanced materials science.
Compact pinless connectors further improve signal-to-noise ratio and feature one-handed plug-
and-play connection.

User-Driven Design
Designed by users for users: Siemens Healthineers hosted 170 workshops
with 365 ultrasound users worldwide to re-imagine every detail and reduce complexity.
In an independent study, the ACUSON Sequoia earned a System Usability Score (SUS)
of 86% and a user-preference score of 82%, scoring higher than the conventional systems
