TL;DR: In this paper, a transducer is configured to transmit a series of ultrasonic signals at a plurality of corresponding locations along soft tissue of a jaw and receive a number of echo signals.

TL;DR: In this paper, the effects of phase aberration are broadening of the system point spread function that deteriorates the image resolution, and increasing the off-axis response leading to multiple images for the target.

TL;DR: In this paper, the effect of subdicing depth and width on the dispersion and resonance behavior of elastic guided wave propagation in 1D array transducers was theoretically analyzed, where the transducer is modeled as a periodic structure with the representative cell composed of one element and a semi-analytical finite element (SAFE) method was derived to obtain the disper sion curves, group velocity and resonance mode shapes of a piezoelectric structure with arbitrary cross-section and periodic boundary conditions.

TL;DR: Flow-mediated vasodilatation measurement in brachial and other conduit arteries has become a common method to asses the endothelial function in vivo, and automatic measurement techniques have been implemented.

TL;DR: Results show that a rectangular wave is effective in improving the visibility of microbubbles, and use of rectangular pulses with 4 and 2 harmonics showed no significant difference in backscatter behavior, indicating that a two-frequency excitation may be sufficient to induce nonlinear behavior of the microbubble at modest incident pressures.
