Improve patient management with reproducible, reliable measurements that work to increase speed of diagnosis
Experience elastography technologies that are easy to operate and provide additional information for diagnoses

Manual Elastography Using eSie Touch Elasticity Imaging

eSie Touch™ elasticity imaging uses gentle compression to provide a high-resolution elastogram, depicting relative tissue stiffness. It forms the elastogram by computing relative tissue deformation globally and displaying the information within a user-defined region of interest. Axial detection pulses are continuously transmitted throughout the field of view to provide information about the state of tissue deformation along each axial line at a specific point in time. Using this technique, stiff and soft tissue may be differentiated even when the tissues appear isoechoic on the B-mode exam.

eSie Touch Elasticity Imaging
By producing high-resolution elastograms that assess tissue stiffness resulting from disease, eSie Touch™ elasticity imaging provides important qualitative information about disease progression.

Manual Elastography Benefits

Quality Factor – Provides real-time qualitative feedback to assist users in optimizing their acquisition technique. The real-time numerical elastogram quality score provides additional information for selecting optimal images for review.
Elastographic Maps – High-resolution elastographic images may be visualized using a variety of grayscale and color maps.
Shadow Measurements – Measurement calipers are automatically applied to both images in a side-by-side display for comparison of elastograms.
Transducer Support - eSie Touch elasticity is supported on linear, endocavity and curved array transducers.

eSie Touch elasticity imaging is available on the ACUSON S1000^TM, ACUSON S2000^TM, and ACUSON S3000^TM ultrasound systems.

Clinical Use

Siemens’ elastography imaging technologies deliver new insights that redefine the way you assess and treat disease. Along with offering exceptional assessments of tissue characteristics, they cover a wide range of exam types, ensuring you have the right solution for every patient.

Small Parts Imaging with Virtual Touch IQ

Designed to improve targeting for biopsy locations, Virtual Touch™ IQ gives you the ability to visualize quantifiable differences in tissue elasticity. In addition, this technology offers a high level of resolution, equipping you to assess and monitor lesions as small as 3 mm.

Liver Imaging with Virtual Touch Quantification

Virtual Touch™ quantification can be utilized to obtain a baseline stiffness value in patients with signs or symptoms of liver disease. A change from this baseline stiffness value during routine follow up can indicate disease progression/regression.

Advanced Abdominal and Small Parts Imaging with Virtual Touch Imaging

Offering enhanced border definition and the ability to identify the stiffest portion of a lesion, Virtual Touch™ imaging works to improve the accuracy of your diagnostic measurements. When paired with superior image quality, this technology promotes a higher level of diagnostic understanding.

Abdominal and Small Parts Imaging with eSie Touch Elasticity Imaging

Combining manual compression with real-time, qualitative conventional ultrasound, eSie Touch™ elasticity imaging provides a more complete view of tissue stiffness. This additional clinical information works to enhance the accuracy of disease assessment and monitoring.

Technical Details

How Virtual Touch Works

Through the use of Acoustic Radiation Force Impulse (ARFI), Virtual Touch™ technologies are able to penetrate deep tissue with speed and precision. Available on the ACUSON S2000 and ACUSON S3000 ultrasound systems, these tools deliver detailed information that supports improved disease assessment and monitoring, helping you avoid unnecessary biopsies. The result is enhanced diagnostic capabilities driven by the ability to explore tissue stiffness in greater detail.

A Simple, Four-Step Process

An acoustic push pulse is applied to compress tissue in a user-defined region of interest
This push pulse displaces tissue and generates shear waves that propagate perpendicularly to the push wave
A Siemens-exclusive algorithm automatically measures the velocity of these shear waves
You are then able to view qualitative assessments and/or quantitative measurements of the mechanical stiffness of tissue
