Elastography

Elastography (or tissue elasticity imaging) is an imaging modality that detects

relative differences in tissue stiffness. This technique is derived from tissue

palpation, which is performed during traditional physical examinations to detect

tissues of different relative stiffness or strain. The magnitude of estimated strain is

depicted in the form of a color or grayscale display. Differences in estimated

relative strain between tissues may be demonstrated within the field of view via

different colors assigned to those tissues based on the estimated strain

measurement.

WARNING: Tissue elasticity is an estimation of the relative strain and at this time

is not a quantifiable parameter.

Elastography is an optional capability available on ZONARE L8-3, L10-5, L14-5sp,

and L14-5w transducers. It may be activated by pressing a programmable mode

button configured for Elastography on the

SmartCart/SmartCart sp or via Menu

Control on the undocked

Scan Engine.

Configure Mode/Function Key

If a SmartCart/SmartCart sp programmable Mode or Function button is not

preconfigured for Elastography imaging, you can configure a button as follows:

1. Go to: Setup button | System Setup | Keys

2. Choose the desired Mode or Function button and select Elastography from its

pull-down menu.

3. Then select Apply at the bottom of the Keys page to exit and return to live

imaging. The button is now configured for Elastography. (See also

“Programmable Keys” on page 7-9.)

Display Formats

The default display format for Elastography mode is Dual. The B-Mode image

displays on the right and the Elastography image displays on the left.
