Spatial Distribution of the Speed of Sound in Biological Materials with the Scanning Laser Acoustic Microscope
TLDR
In this article, an automated technique for determining the speed of sound using the scanning laser acoustic microscope (SLAM) has been developed, which can be used to develop indices that quantify the spatial gradient of the tissue's speed.Abstract:
Abstmct-An important ultrasonic propagation property for tissue characterization is the speed of sound. The scanning laser acoustic microscope (SLAM) provides the capacity to determine the speed of sound in tissue specimens or portions of specimens on the submillimeter scale. This capability potentially can be utilized to develop indices that quantify the spatial gradient of the tissue’s speed of sound. An automated technique for determining the speed of sound using the SLAM has been developed. It is now possible to study quantitatively the degree of tissue heterogeneity from SLAM measurements of the speed of sound distribution. Tread more

Relation of Ultrasonic Backscatter and Acoustic Propagation Properties to Myofibrillar Length and Myocardial Thickness
TL;DR: Ulasonic backscatter and propagation properties are directly related to sarcomere length and myocardial thickness and may be responsible for cardiac cycle-dependent variation in back scatter.

TL;DR: As the wounds healed there appeared to be an increase in both speed and attenuation coefficient although the wound age at which these increases started and the length of time for which they continued varied from one dog to the next.

Acoustics: An Introduction to Its Physical Principles and Applications
TL;DR: Pierces as mentioned in this paper is a classic text on acoustics with a rich history and development of the field of sound and acoustical engineering. But he organizes it superbly and writes intelligently with a wonderful way of integrating the history and evolution of the science and the graphics are exceptionally clear and communicative.

Acoustic microscope operating at 100 MHz.
TL;DR: As acoustic microscopy relies on mechanical vibration, rather than electromagnetic radiation, it may be possible to visualize features of a specimen which go undetected by conventional methods.
