Excitation of ultrasonic Lamb waves using a phased array system with two array probes: Phantom and in vitro bone studies.

Highlights: [•] We experienced the use of a PA system with two probes to study guided waves. [•] We used brass plate and bone plate as samples. [•] We studied the effect of steering angle on the excitation of guided waves in plates. [•] We found the change of the phase velocity spectrum with steering angles in agreement with the source influence theory. [•] It is feasible to use the PA system with two probes to perform in vivo study. [ABSTRACT FROM AUTHOR]
