YOUNGS MODULUS MEASUREMENTS OF SOFT-TISSUES WITH APPLICATION TO ELASTICITY IMAGING

Ultrasound elasticity imaging is a promising method that may eventuall y allow early detection of many tissue pathologies. However, before el asticity imaging can be applied to its numerous potential clinical app lications, the quantitative accuracy of tissue elasticity measurements must be established. Simple 1-D ultrasound elasticity measurements we re performed on muscle and liver and compared with independent and est ablished mechanical measurements to investigate both the accuracy and consistency of ultrasound elasticity measurements. In addition, some i nteresting properties of soft tissue and aspects of the measurement pr ocess which should be considered in elasticity measurements are discus sed.
