Appendix A Technical Description
Instructions for Use A - 17
Virtual Touch IQ Option
(Available only on the ACUSON S2000 system and the ACUSON S3000 system)
 Compatible transducer: 9L4
Supported studies: Breast, Thyroid
 Uses acoustic radiation force impulse (ARFI) technology of diagnostic ultrasound to induce
tissue displacement
 Qualitatively depicts shear velocity for a selected region of interest on a 2D image
 Provides quantitative measurements of shear velocity (Vs) and elasticity (E) for selected
points within the region of interest
 Provides shear velocity and elasticity measurement labels for the breast and thyroid exams
 Supports all basic measurements in either a full-screen format or a dual-screen format
3-Scape Real-Time 3D Imaging Option
WARNING: To avoid technique-related artifacts, you must be thoroughly familiar with the
techniques of 3D and 4D imaging. Read the entire 3D and 4D imaging chapter before using the
3-Scape real-time 3D imaging or fourSight 4D ultrasound imaging technology.
 The 3D imaging feature is a system option that allows the acquisition of three-dimensional
ultrasound images. MultiPlanar Rendering (MPR) provides a view of each segment of the
volume as an arbitrary slice.
 Real-time reconstruction after free-hand acquisition
 MultiPlanar Rendering demonstrates imaging planes not accessible with normal scanning
techniques
