Young's modulus is a relationship between elasticity, strain, and stress:
- elasticity x (change in length / original length) = (force / area)
put another way, this is
- elasticity x (strain) = stress
or
- elasticity = stress / strain
Elasticity is measured in kilopascals (kPa).
This relationship is fundamental to strain elastography and shear wave elastography.
The Young's modulus can be calculated as1
Young's modulus, E = 3 x Tissuetissue density x (Shear(shear wave velocity)2
