Designed to address today’s challenges in ultrasound imaging

Experts agree that a conventional one-size-fits-all approach to patient care falls short of addressing the challenges of demanding caseloads, patient diversity and user variability.

Healthcare providers want advanced technologies and applications that intelligently respond to both patient- and user-specific needs. Tailoring diagnosis and therapies to each patient’s individual profile helps to improve clinical, operational and financial outcomes.

The ACUSON Sequoia ultrasound system uses BioAcoustic imaging to reduce the effects of ultrasound variability between users, patients and technology delivering greater clinical insights and precision medicine.

Acoustic variability

1.9 billion overweight
650 million obese

Ultrasound users are faced with a patient population that is increasingly harder to scan.

World Health Organization (WHO), 2016

Technological variability

Ultrasound devices are complex products. Differences in technology can inhibit the user’s ability to generate accurate and reproducible measurements during an exam.

User-specific variability

Studies have demonstrated that significant intra- and inter-observer variability can pose a challenge to the standardization of care delivery.

InFocus Imaging and InTune Transducer Technology for all patients

Fully focused images in record time

The ACUSON Sequoia system’s powerful architecture eliminates the need for conventional focal zones to create a fully focused image with faster frame rates than conventional systems.

InFocus uses synthesized, retrospectively focused transmit beams throughout the field of view that focuses at all depths. More information is harvested from the usual transmit sequence, using massive overlapping multibeam groups rather than individual or close parallel beam lines as in conventional systems. Secondary beamforming is enabled with InFocus and physics-based delay technologies. Amplitude corrections can be made across transmit events to significantly sharpen the image and improve spatial resolution beyond what is typical for a given transducer frequency. 

Offering the best signal fidelity

Next generation transducers specifically designed to produce optimal acoustics for each clinical use case. The acoustic matching between transducer and patient was optimized using advanced materials science and optimized test protocols, together with the electrical signal path between the transducer and system, resulting in superior signal fidelity.

Compact-pinless connectors further improve signalto-noise ratio and feature one-handed plug and play connection.

DAX – a transducer so unique we had to give it its own name.

7L2 – deep linear transducer for additional diagnostic confidence

Image deeper

Scanning technically difficult patients can be a daily challenge for many ultrasound users. The innovative DAX and new 7L2 deep linear transducers are dedicated tools that allow you to see deeper, providing diagnostic confidence when you need it most.

InFocus imaging
Fully-focused imaging of the liver and IVC utilizing InFocus Technology that delivers image uniformity throughout the field of view.

The power of AI-enabled tools such as eSieCalcs can measure the long axis, short axis and circumference of structures like this thyroid mass above.

High frequency linear transducer
Utilizing the high frequency 18L6 transducer you can visualize structure in greater detail resolution like this supraspinatus tendon

Color flash suppression
Using smart algorithms, Color Flash Suppression Technology can automatically reduce flash artifact experienced from patient or transducer motion.

Slow flow
Using smart filters and adaptive signal enhancement, slow flow can image smaller, low-flow vessels further into tissue like this kidney with reduced flash artifact.

Doppler TEQ
Visualize clean and clear Doppler waveforms thanks to Doppler TEQ. Scale, gain and baseline are adjusted automatically with full post-processing capabilities.

Speed of sound correction
Adjusting the speed of sound improves contrast and detail resolution allowing for the most accurate representation of the tissue like this breast example.

High frequency curved transducer
Superior contrast resolution of this 21-week fetus utilizing the 9C3 palmer grip transducer for improved ergonomic work flow.

Volume imaging
3D/4D imaging allows you to visualize anatomy in new dimensions for improved confidence like this coronal view of an IUD.

Single crystal

Personalized Advanced Applications

Patient-centered approach to diagnosis

The ACUSON Sequoia was built from the ground up with dedicated hardware for exceptional performance in applications such as contrast enhanced ultrasound (CEUS) and elastography.

With its industry leading performance, the ACUSON Sequoia system enables healthcare professionals to access the clinical information needed for personalized precision medicine.

This unique patient-centric approach to diagnosis leverages the comprehensive advanced applications toolbox offered by the ACUSON Sequoia system – from quantification and characterization of tissue to interventional procedures.

Tissue characterization using CEUS imaging can lead to faster diagnosis.

Tissue quantification using shear wave elastography imaging can improve diagnostic results while reducing costs.

Virtual Touch Strain Elastography
Provide a simple and qualitative measure of lesion stiffness relative to the surrounding tissue in color and gray scale maps as demonstrated in this image of testicular torsion.

Virtual Touch pSWE
Raise the benchmark for shear wave accuracy when compared to conventional ultrasound providing tissue stiffness quantification with increased confidence in the liver.

Virtual Touch 2D SWE
Display qualitative and quantitative color maps to measure shear wave speed with precision and repeatability, like this example of the renal interface.

CEUS imaging
The ACUSON Sequoia has twice the sensitivity than previous systems for improved diagnostic confidence.

Velocity Vector Imaging
Assess myocardial motion and mechanics with global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) using semi-automated syngo VVI.

Fusion imaging
Combine imaging modalities like this example of CT and ultrasound fusion for improved diagnostic confidence.

Designed by users, for users

The variability inherent in the ultrasound scanning process can pose a challenge for users. In an effort to eliminate variability, Siemens Healthineers hosted 170 workshops with 365 ultrasound users worldwide to create an ultrasound system designed by users, for users.

Leveraging automation, machine learning and listening to ultrasound users, every detail was re-imagined to reduce complexity and improve user experience.

Preferred by users

Overall usability of an ultrasound system determines how well advanced technologies and diagnostic tools are able to expand healthcare professional’s clinical capabilities. The ACUSON Sequoia was evaluated by an independent user experience design and development company in terms of user performance and user satisfaction.

The ACUSON Sequoia earned a system usability score (SUS) of 86% and user preference score of 82%, scoring higher than the conventional ultrasound systems participating in the study
