TWO-DIMENSIONAL Pb(ZrxTi1-x)O3 CERAMICS ARRAYS FOR A HIGH-SPEED THREE-DIMENSIONAL IMAGING SYSTEM USING A CODED WAVEFRONT

A 2-D matrix Pb(ZrxTi1-x)O3 (PZT) ceramics array has been developed to evaluate the principle of an imaging system using a coded wavefront. Fabrication of a PZT 40 x 40 element array for transmitter and receiver is described. Signals modulated by the Walsh functions were used for driving the transmi...

Zusammenfassung:A 2-D matrix Pb(ZrxTi1-x)O3 (PZT) ceramics array has been developed to evaluate the principle of an imaging system using a coded wavefront. Fabrication of a PZT 40 x 40 element array for transmitter and receiver is described. Signals modulated by the Walsh functions were used for driving the transmitter array elements. 3-D images were obtained for a standard ultrasonic phantom. This method is applicable in medical diagnosis. 7 refs.
