TL;DR: A time-frequency analysis was applied to determine the sound speed thorough the tissue with Frequency dependence of sound speed was obtained with a myocardium of a rat sliced into 10 microm.

TL;DR: A new concept sound speed microscopy that can measure the thickness and speed of sound in the tissue using fast Fourier transform of a single pulsed wave instead of burst waves used in conventional SAM systems is proposed.

TL;DR: The development of parallel fiber in cerebella cultures was clearly observed as the contrast in acoustic impedance, without staining the specimen, as the technique is believed to be a powerful tool for biological tissue characterization, as no staining nor slicing is required.

TL;DR: The pulse wave is volumetric change induced by heartbeat or inflowing blood, and significantly depends on the propagating path and stiffness of the artery, and the PWV in each phase may be used as the index for diagnosing stages of arteriosclerosis progression.

TL;DR: Ultrasonic microscopy is expected as a powerful tool for biological tissue characterization and its clinical application to histopathological examination during surgery is being considered.
