An adaptation of the ultrasound transducer element test for multi-row arrays

1-3 Piezoelectric Composite Ferroelectric Materials in Smart Medical Ultrasonic Diagnostic Transducers

“…Combined with the research progress at home and abroad, different scholars have made certain explorations in the finite element research of ultrasonic transducers and ferroelectric materials: Dudley N J studied A simple "connector test" was studied to diagnose the operation of the elements in the ultrasonic transducer array, and has been applied to the phased array, the purpose is to further adjust the multi-line transducer array test [1]. Westerway SC studied Australia's findings on medical ultrasound disinfection and hygiene practices, and the results emphasized that there is an urgent need to update medical ultrasound infection prevention and control guidelines [2].Hager PA proposed a configurable beam former , and proved that the entire 3-D delay and summing beamforming can be fully digitalized on a single chip, without the need for off-chip memory [3].Lee W gave an overview of medical ultrasound imaging transducers, and detailed structural components of typical transducers.…”

“…The key points of research and innovation of this article are as follows: (1) This article gives a comprehensive introduction to the ultrasonic transducer, and gives the finite element analysis of the 1-3 piezoelectric composite ferroelectric material; (2) The effect and far-reaching influence of PZT volume fraction, aspect ratio and the number of primitives on the finite element modeling of 1-3 spherical crown piezoelectric composites are discussed. Then it was verified by experiment and ANSYS performance analysis of ultrasonic diagnostic transducer.…”
