Acoustic and elastic wave propagation is being investigated in media such as the ocean, the earth, biological tissues and solid materials. In these different areas, many specific imaging techniques have been developed which differ in the wavelength of the sound, its polarisation and the instrumentation used. In this interdisciplinary book, leading experts in underwater acoustics, seismology, acoustic medical imaging and non-destructive testing present basic concepts as well as the recent advances in imaging. The different subjects tackled show significant similarities. This volume gives an up-to-date-overwiew of the field and is intended for scientists and graduates alike.
