Abstract
The invention relates to a multiple-element acoustic probe comprising piezoelectric transducers (Tij) and an array of interconnections connecting the acoustic transducers to an electronic signal processing and control device. This probe further comprises a continuous ground electrode (P) integrated between the transducers and acoustic matching elements, facing the piezoelectrical transducers, the acoustic matching elements being totally uncoupled from one another mechanically.
Claims13
An acoustic probe comprising acoustic matching elements (Aij), elementary piezoelectric transducers (Tij) and an array of interconnections connecting the acoustic transducers to an electronic signal processing and control device characterized in that said probe comprises a continuous ground electrode (P) inserted between the elementary acoustic transducers (Tij) and acoustic matching elements (Aij).
