摘要

Abstract

The use of pulsed acoustic microscopy (50–200 MHz) makes it possible to analyze the three-dimensional microstructure and uniformity of the elastic properties of hydrated composite biomaterials. This paper proposes a method for local assessment of acoustic properties in spongy polymer samples, based on visualizing the microstructure, measuring attenuation, and sound velocity. This approach is relevant to the study of biopolymer composite materials and their structures, as it allows for in situ observation of structural degradation under external influences, as well as investigation of the evolution of native tissue replacement, if necessary.
