Ultrasound-mediated imaging of soft materials /

Ultrasound-mediated imaging in scattering media has deeper roots than hitherto imagined, with roots in condensed matter physics. Professors Vasu and Roy discuss these in order to establish a firm connection between measurement and a host of parameters in the medium, mechanical and optical. These con...
