Journal ArticleDOI
Theory and operation of 2-D array piezoelectric micromachined ultrasound transducers
TL;DR: Piezoelectric micromachined ultrasound transducers are a new approach for the construction of 2-D arrays for forward-looking 3-D intravascular (IVUS) and intracardiac (ICE) imaging.
Patent
Piezoelectric micromachined ultrasonic transducer with air-backed cavities
TL;DR: In this article, a piezoelectric micromachined ultrasonic transducer comprising a substrate and a first dielectric film formed on the substrate is presented.
Patent
Enhanced ultrasound imaging probes using flexure mode piezoelectric transducers
TL;DR: In this paper, a method of generating an enhanced receive signal from a piezoelectric ultrasound transducer is described, which consists of providing an acoustic signal by the PEO element, applying a DC bias to the PIO element prior to receiving the acoustic signal and/or concurrently with receiving the audio signal, and generating an enhancement of the received acoustic signal as a result of receiving the PA signal.
Journal ArticleDOI
