ABSTRACT

Over the past decades, ultrasound imaging technology has satisfied outstanding improvement in obtaining significant diagnostic information from patients in a fast, noninvasive approach. Piezoelectric transducers are important elements of various broadband ultrasonic systems, either pulse-echo or through-transmission, used for imaging and detection purposes[1]. In ultrasonic broadband applications such as medical imaging, or non-destructive testing, piezoelectric transducers should generate/receive ultrasonic signals with good efficiency over a large frequency range. This implies the use of piezoelectric transducers with high sensitivity, broad bandwidth and short-duration impulse responses.High sensitivity provides large signal amplitudes which determine a good dynamic range for the system and the short duration of the received ultra-sonic signal provides a good axial resolution. This paper presents the simulation of 8-element linear array transducers with center frequency 10 MHZ,using Field-II GUI program for ultrasonic measurements.
