Tissue Strain Analytics
Siemens ACUSON ultrasound systems feature a comprehensive range of tissue strain analytic applications that enable qualitative visual or quantitative value measurements of the mechanical stiffness properties of tissue. This new dimension of information is not available using conventional sonographic imaging, and represents the most important development in ultrasound technology since the advent of Doppler imaging.
Virtual Touch tissue imaging
Virtual Touch™ tissue imaging* applications, available exclusively on the ACUSON S2000™ ultrasound system, implement Acoustic Radiation Force Impulse (ARFI) technology for evaluation of deep tissues not accessible to superficial compression elastography techniques.
Virtual Touch tissue imaging provides a relative stiffness map for a user-defined region of interest. Virtual Touch tissue quantification is the world’s first and only application for obtaining a numerical value of shear wave speed, related to tissue stiffness, at a precise image-based anatomical location.
eSieTouch elasticity imaging
eSie Touch™ elasticity imaging, available on both the ACUSON Antares™ and ACUSON S2000 platforms, enables high resolution elastography using gentle compression.
Real-time elastogram qualitative feedback assists imagers in optimizing their acquisition technique. An exclusive real-time numerical elastogram quality score** provides additional information for selecting optimal images for review.
Together, these tissue strain analytic applications provide diagnostic information that is not available through previous ultrasound technologies.
Ultrasound Tissue Strain Images
Virtual Touch tissue imaging*
Siemens exclusive implementation of Acoustic Radiation Force Impulse (ARFI) technology allows rapid visualization of relative stiffness within a user-defined region of interest. Simultaneous display of conventional sonographic and stiffness map images enables detailed evaluation of any region of interest.
Virtual Touch tissue quantification*
Using image-based localization and a proprietary implementation of Acoustic Radiation Force Impulse (ARFI) technology, shear wave speed may be quantified at a precise anatomical region. Measurement value and depth are conveniently reported.
eSie Touch elasticity imaging
Through gentle transducer compression cycles, high resolution elastographic images are generated and may be visualized using a variety of grayscale and color maps. Both superficial and endo-cavity** transducers are supported. Elastographic features are easily compared side-by-side with conventional sonographic images using automatic “shadow copy” of measurements. Visual feedback indicates images with excessive motion artifact. In addition, a real-time elastogram quality factor** is displayed to facilitate rapid identification of optimal images for review.
