Ultrasound-mediated imaging in scattering media has deep roots in condensed matter physics. This book explores these roots and provides a comprehensive review of imaging with light and ultrasound, focusing mainly on recovery of mechanical contrasts. It is suitable reference material for graduate students and practitioners in the field.
Ultrasound-mediated imaging in scattering media has deeper roots than hitherto imagined, roots in condensed matter physics. Vasu and Roy discuss this in order to establish a firm connection between measurement and a host of parameters in the medium, mechanical and optical. These connections are verified through the recovery of parameters using simulations and experiments. Explaining their research, inter alia, the authors explore problems such as noise-assisted small-signal amplification, stochastic search schemes for optimization and anisotropic particle diffusion. For graduates and researchers in the field, this book will highlight key features of the developing science and will enable practitioners to adopt the simulation algorithms and experimental modalities presented.
