Increasing transducer bandwidth and signal to noise ratio (SNR) is fundamental in improving the quality of medical ultrasound images. A multilayer PZT/polymer composite hybrid array that will not require post alignment is developed. This structure consists of a layer of 5 MHz 1-3 composite material on top of conventional 5 MHz PZT which will provide greater SNR relative to conventional composites and increased bandwidth over multilayer PZT. Finite element simulations show that for a 2 MHz linear array element, the 2 layer hybrid structure increases the pulse echo SNR by 7.5 dB over that from a single PZT layer PZT element.
