An ultrasound transducer (100) includes an array (114) of PZT elements (115) mounted on a non-recessed distal surface of a backing block (110). Between each element and the backing block is a conductive region (125, 126) formed as a portion of a metallic layer sputtered onto the distal surface. Traces (104, 105) on a longitudinally extending circuit board (102) - preferably, a substantially rigid printed circuit board, which may be embedded within the block - connect the conductive region, and thus the PZT element, with any conventional external ultrasound imaging system. A substantially "T" or "inverted-L" shaped electrode is thereby formed for each element, with no need for soldering. At least one longitudinally extending metallic member (120, 121) mounted on a respective lateral surface of the backing block forms a heat sink and a common electrical ground. A thermally and electrically conductive layer (125), such as of foil, transfers heat from at least one matching layer mounted on the elements to the metallic member. |
