Acoustical Imaging 18

Technology allows humans to "see" with sound, (something that bats, whales, and dolphins can do unaided); and advances in that technology have produced sophisticated techniques that defy categorization into the three fundamental types of acoustic imaging pulse-echo, phase-amplitude, and amplitude mapping. Papers from the 18th International Symposium on Acoustical Imaging held in Santa Barbara, California, Sept. 1989, address biomedical applications, imaging systems, advanced imaging techniques, nondestructive evaluation, acoustic microscopy, seismic imaging, parameter estimation and detection, multidimensional imaging, underwater imaging, and transducers.
