Two types of transducers for small ultrasound probes were fabricated. Titanium or epoxy resin were 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 16μm, a frequency bandwidth of 69MHz in the range of 39 to 98MHz, and a fractional bandwidth of 86% at the epoxy resin backing probe.
