Abstract

Acoustic micrographs of unstained specimens of mouse kidney were produced at frequencies of 100 MHz and 220 MHz with resolutions of 20μ m and 9μm, respectively. The acoustically revealed structure has been examined in relation to established microanatomy. High contrast details corresponding to connective tissue boundaries of supporting elements of the nephron are exhibited. In addition, various regions of the kidney such as the cortex and the three medullary regions can be differentiated. At these frequencies, the acoustically exhibited structures are considered to result from scattering at connective tissue interfaces, resulting from local acoustic impedance discontinuities, rather than from intrinsic acoustic absorption within the microstructures of the tissue.
