Evaluation of small ultrasonic probe using lead zirconate titanate poly-crystal film deposited by hydrothermal method

Two types of transducers for small ultrasound probes were fabricated. Titanium or epoxy resin was used for the backing material of the transducers. The piezoelectric material was lead zirconate titanate (PZT) that was deposited by the hydrothermal method. These transducers were built into a small ul...

Zusammenfassung:Two types of transducers for small ultrasound probes were fabricated. Titanium or epoxy resin was used for the backing material of the transducers. The piezoelectric material was lead zirconate titanate (PZT) that was deposited by the hydrothermal method. These transducers were built into a small ultrasound probe and the characteristics were evaluated. As a result, we succeeded in the fabrication of a wideband ultrasound probe with a distance resolution of 16 μm, a frequency bandwidth of 69 MHz in the range of 39 to 98 MHz, and a fractional bandwidth of 86% at the epoxy resin backing probe. © 2012 Wiley Periodicals, Inc.
