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.

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.
