Book 1975y 4-7, 1975. The title of this symposium differs from that of the first four by the addition of the word "Imaging", reflecting an increase in emphasis on nonholographic methods of acoustical visualization. For convenience, no change has been made in the title of this published series. The 38 papers

Auditory and Vestibular Researchs. Selected clinical results, including in vivo images of several near term fetuses, are presented and discussed. Finally, we comment on through-transmission acoustical holography as a modality for soft tissue diagnosis.

Sokolowskins within the tissue specimen with a resolution of 64 by 64 elements (< 2 mm square), The disadvantage of TOF reconstruction is that transmission scanning is required. Advantages over B- and C-scan imaging are: 1) dynamic changes in gain of receiver are not required, 2) attenuation occurs on only on

Applications (III) – Noise Measurementwill present and discuss two schemes for implementing the PST approach. A key element in each of the schemes is an acousto-optic transducer which is activated by a light pattern. Scanning can be achieved either electronically or mechanically by putting the light pattern into motion. Focusing can be
