Ultrasonic guided waves in bone
TL;DR: The promises and challenges related to bone characterization by ultrasonic guided waves are discussed, with a strong potential over the standardized bone densitometry as a tool for bone assessment.
Journal ArticleDOI
Mode separation of Lamb waves based on dispersion compensation method.
TL;DR: A method of dispersion compensation is proposed for the purpose of mode separation by compensating the individual dispersive waveforms into temporal pulses, which thereby become nearly un-overlapped in time and frequency and can thus be extracted individually by rectangular time windows.

A method and device for the non-invasive assessment of bones
TL;DR: In this paper, an ultrasonic wave is introduced into a bone in such way as to produce one or more guided wave modes within the bone, and the signals emerging from the bone are stored and analyzed to determine the propagation characteristics of the guided wave/s.
Patent
Method and device for the non-invasive assessement of bones
TL;DR: In this paper, an ultrasonic wave is introduced into a bone in such way as to produce one or more guided wave modes within the bone, and the signals emerging from the bone are stored and analyzed to determine the propagation characteristics of the guided wave/s.

TL;DR: In this article, an affordable laser diode array can selectively launch either the S0 or A0 ultrasonic wave mode at a chosen center frequency into a polymer plate, and a predetermined time delay matching the selected mode and frequency was employed between the output of the elements.
