Akustisk sonde med flere elementer indbefattede en fælles jordelektrode

摘要

A method of manufacturing a multiple-element acoustic probe including piezoelectric transducers and an array of interconnections connecting the transducers to an electronic signal processing and control device. The probe also includes a continuous ground electrode integrated between the transducers and the acoustic matching elements, facing the piezoelectric transducers, the acoustic matching elements being totally uncoupled from one another mechanically. This probe may be used in medical imaging or underwater imaging.
