Elastography
CAUTION:
It is provided for reference, not for confirming a diagnosis.
Strain Elastography
Strain Elastography is a separately purchased option. Elastography must be
configured to a programmable function before use. These keys can be configured in
Setup/Keys.
Once configured, elastography is invoked by pressing the configured function key. By
default the image goes to a dual display, with the elastography image on the left and a
reference image on the right. Pressing the
Dual key will toggle to a display only showing the
elastography image.
Elastography is available for the following transducers: L8-3, L10-5, L14-5w, L14-5sp, L20-5.
Elastography supports three types of strain acquisition. The softkey OLEDs can be used to
choose between these:
•
Relative (normalized) strain: This generally has similar sensitivity to hard and soft tissue.
•
Absolute strain: Strain is displayed without normalization.
•
Cross-correlation: This assesses the quality of the acquisition by comparing
frame-to-frame correlations.
While in Elastography dual display, generic measurements can be done on either image. A
measurement performed over the strain image will also display on the reference B-mode
image.
ARFI (Acoustic Radiation Force Impulse Imaging)
