5-2-8-9 Elastography
Elastography shows the spatial distribution of tissue elasticity properties in a region of interest by
estimating the strain before and after tissue distortion caused by external or internal forces. The strain
estimation is filtered and scaled to provide a smooth presentation when displayed.
With Elastography active, the image will show a color map/bar indicating the level of elasticity detected
by the system. The Elastography image is achieved by pulsating the probe manually while you are
scanning the anatomy of interest.
5-2-8-9-1 Shear Wave
With the Shear Wave option, the scanner creates the distortion by generating shear waves in tissue
using a diagnostic ultrasound transducer. Shear waves "push" the tissue at a low frequency in either a
single burst of high amplitude, long duration pulses or a series of such pulses.
