Abstract

This paper investigates multiple-resonance transducers using 1-3 composite materials based on a thin piezoelectric transducer bonded with a thick plate resonator. The application of the transducer to clinical diagnosis involves speckle reduction using a compound-frequency method. Imaging experiments using pork liver, meat, and a phantom were conducted and demonstrated that flat, broadband characteristics are important in a multiple-resonance transducer used for multiple-frequency imaging.
