About Strain Graph

The strain graph displays the variation over time of tissue strain caused by compression in real time. Pressing the tissue which you want to image so that the periods and amplitudes of the Strain Graph are constant makes it possible to create a stable Elasto Mode image.

Pressing probe (applying pressure to tissue) → Positive value Withdrawing probe (releasing pressure from tissue) → Negative value

* Stronger pressure increases the amplitude. Gentler pressure reduces the amplitude.
