Research Abstract:

The Laboratory for Ultrasonics within the Physics Department investigates the anisotropic elastic and viscoelastic properties of cardiovascular tissue and of bone. Experimental studies of hearts, arteries, and bones are carried out using ultrasonic techniques developed in our laboratories. Guided by our experimental data obtained from ultrasonic phase velocity, attenuation and scattering measurements, we develop and test models of the physical properties of tissue. We measure the components of the fourth-rank viscoelastic stiffness tensor as part of these investigations. Of particular interest is the role of specific proteins in determining the elastic and viscoelastic properties of tissue. One application of this research is the use of quantitative ultrasonic imaging (“tissue characterization”) to evaluate myocardium, as an extension of clinical echocardiography. Another application is the physics underpinning bone sonometry, a tool for understanding the progression and potential reversal of osteoporosis.
