Abstract

An intravascular forward-looking ultrasonic probe has been fabricated using batch fabrication. This probe consists of eight separated elements ring array 1-3 composite transducer and a backing made from conductive epoxy. The conductive epoxy backing works not only acoustic dumping material but also electrical interconnection. Almost same impedance properties and pulse-echo waveform from each of the eight elements have been measured. Reflected pulse-echo by an acrylic plate placed at appropriately 4.5 mm front of the probe has been detected from each of the eight transducer elements in water.
