Virtual Touch technologies give you the ability to:

  • Go beyond standard elastography by visualizing and quantifying tissue stiffness, which is often correlated with disease progression
  • Improve diagnostic confidence by evaluating the heterogeneity of lesions and tumors and identifying lesion boundaries
  • Pinpoint biopsy locations through the identification of the stiffest areas of tissue
  • Greater in-depth analysis and consistent monitoring on a wide variety of exams – liver, breast, thyroid, and other organs
  • Achieve a more comfortable exam experience with a non-invasive ultrasound procedure
  • 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

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.

  • 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 S1000TM, ACUSON S2000TM, and ACUSON S3000TM ultrasound systems.

Caractéristiques techniques

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

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