ACUSON Sequoia™ Ultrasound System Virtual Touch 2D SWE-Small Parts | VA25 Software Release

ACUSON Sequoia ultrasound system VA25 SW release Virtual Touch 2D SWE Quick Reference Card COBY siemens-healthineers.com/ultrasound Using 2D shear wave elastography (SWE) to measure shear velocity (Vs) in meters per second (m/s) and elasticity (E) in kilopascal (kPa) | Small Parts Application Step 1 OL4 Step 3 Breast SWE • Select compatible transducer and • SWE tab is default application on exam preset1 touch screen Step 2 Step 4 Update • Press VT (Virtual Touch) located on VT • Roll trackball to reposition control panel the region of interest (ROI) • Press right or left Set key and roll trackball to resize ROI • Use minimal scanning pressure to prevent pre-compression effect • Press Update on control panel to begin acquisition 1 2D SWE imaging is compatible with 5C1, DAX: General, Abdomen; 10L4: General, Thyroid, Breast, MSK; 18L6: General, Thyroid, Breast. SIEMENS Healthineers Step 5 Step 6 Unit • When acquisition is complete, system automatically m/s • If desired, select Unit m/s to display freezes, emits one audible “beep” and activates the 2D SWE image as an elasticity Velocity or Elasticity display mode image in kPa SWE Live Dual • Adjust Min and/or Max Velocity or Elasticity • If desired, select Live Dual to display Increase range if measured value exceeds range by the SWE image in full-screen format - displaying “High” or, • If desired, select SWE to hide / display Decrease range if better visualization of velocity of - 2D SWE or, VT stiffness differences is needed • Rotate VT on control panel to change • Rotate Shear Wave to view Quality and Displacement transparency of 2D SWE displays Measurements should be taken in regions with - high quality (green to yellow-green) in the Quality display Correlate the areas in the Velocity or Elasticity - image with shear wave signal-to-noise ratio and Displacement amplitude Note: During freeze, a cooling timer indicates remaining seconds until transducer is available for image acquisition. During a short cooling time (e.g., 1–2 seconds), the timer appears and then disappears very quickly. Shear Wave Min Velocity Max Velocity Velocity 0.5 6.5 2 siemens-healthineers.com/ultrasound Measurements Shear Velocity and Elasticity -- + Measurements can be performed or viewed in the Velocity (or Elasticity), Quality or Displacement Shear Velocity display modes. 18L6 • Press Caliper on the control panel IB:0.39 TIC 0.63 6 .0.39 • Shear Velocity is default measurement tool 85% Roll trackball to position measurement ROI. In 2D • OdB/DR65 Live Dual, the measurement ROI can be placed 1446 SWE on either image. Transp: 60% • If needed, rotate ROI Diameter to resize • Shear wave measurements and measurement ROI depth and diameter are displayed near image (Fig. 1) 1 Vs Median=2.36 m/s • To display measurement in report, select E Median=16.7 kPa Depth=0.86 cm measurement label Diam=0.30 cm 2 Vs Median=1.12 m/s E Median=3.8 kPa Depth=0.87 cm • If desired, press Set key and roll trackball to Diam=0.30 cm perform additional measurements Fig. 1: Velocity display mode in Live Dual format and shear wave Select Delete on the control panel to delete the measurements of a breast lesion. • measurement • Select Report on left side of touch screen to view, store, print or transfer shear wave measurements Note: If measurement ROI value exceeds the current maximum velocity or elasticity setting, the measured results display HIGH for the shear wave value. If measurement ROI value is lower than the current minimum velocity and elasticity setting, the measured results display LOW. The measured results display X.XX (for velocity) or XX.X (for elasticity) if the shear wave was not detected within the ROI or if a measurement is performed outside the ROI. Shadow Shadow Duplicates and displays a measurement on the adjacent image for a comparison of lesion size and/or location. 1 D=0.30 cm • In Live Dual, press Caliper on the control panel • Select measurement tool • Shadow is activated as a default on the touch screen • Measure the right or left image • The Shadow measurement is displayed in the measured results Tip: Shadow may be used with the Shear Velocity tool when Live Dual is activated. siemens-healthineers.com/ultrasound 3 For the proper use of the software or hardware, please always use At Siemens Healthineers, our purpose is to enable healthcare the Operator Manual or Instructions for Use (hereinafter collectively providers to increase value by empowering them on their journey “Operator Manual”) issued by Siemens Healthineers.
