Abstract
Considerable interest in the elastic properties of soft tissue has developed in medicine due to their clinical relevance for monitoring the progression of various diseases as well as a biomarker for cancer. Most newly developed imaging modalities use shear wave to estimate the elasticity of tissue. A novel surface wave method has been developed by us for noninvasively estimating the elasticity of tissue. In this paper, we have extended this method for measuring viscoelastic material properties of pig lungs. A small force is generated by a mechanical shaker on the lung. The surface wave on the lung is measured by laser. The viscoelasticity of a 14 Kg pig lung is measured for different pressures.
