A 128 element transducer array with 64 PZT ceramic transmitter elements and 64 PVDF polymer receiver elements is described. The array is working at a frequency of 4 MHz and it has been constructed with the requirements of the ultrasound holographic B-scan (UHB) imaging in mind. The most important of these requirements are high sensitivity and a wide angular response in the azimuth plane. The sensitivity of the PVDF receiver elements of the prototype array, however, was found to be nearly 7 dB less when the response from an electrically tuned PVDF element was compared to the response from an untuned PZT element of the same array as a receiver.
