Acoustic waves : devices, imaging, and analog signal processing

TL;DR: The fabrication and experimental testing of 1-D 23-element capacitive micromachined ultrasonic transducer arrays that have been fabricated using a novel wafer-bonding process whereby the membrane and the insulation layer are both silicon nitride are reported.

TL;DR: The PMN-PT single crystal ultrasonic transducer shows considerably improved performance in sensitivity over the PzT and PZT-based 1-3 composite ultrasonic Transducers.

TL;DR: In this article, the authors discuss the channelization function, the parallel signal processing techniques used in channelizers, the signal processing functions, and the critical channelizer parameters, and tradeoffs at the receiver and channelizer technology levels.

TL;DR: In this article, an ultrasound catheter is described for providing substantially real-time images of small cavities, which is characterized by separate and distinct materials for backing the transducers and for carrying the electronics components.
