Abstract: PROBLEM TO BE SOLVED: To manufacture an array converter easily and inexpensively, without giving big damages to a converter ceramic by coupling a projection curved converter array with a packing member formed to be a curve and cutting the coupled array into small cubes to obtain conversion elements. SOLUTION: Gold coating is applied to a floor face 142 of a packing block 40, where ends 54 of conductive parts 52 of a flexible circuit 50 are arranged in a line to connect the ends 54 electrically. Gold coating is applied to both sides of a bar 150 of a composite array at which an angle between a pattern and a calf of a composite array is 10 deg., the bar is placed on the floor 142, an acoustic matching layer sheet 160 is placed on the bar 150 and the gold coating surface of the floor face 142 and that of the bar 150 are connected electrically through press bonding. Then the bar 150 is cut into cubes by a cube cutter 164 to obtain a converter array element 110. Thus, an array converter with high performance, suppressing unwanted resonance mode and low acoustic impedance is easily manufactured at a low cost.

Abstract: A backing block (10) for an ultrasonic array transducer comprises a flex circuit embedded in a body of acoustic backing material, with conductive traces on the flex circuit (20) terminating at the surface (12) of the body (10) at which an array transducer is mounted and extending out from the rear (14) of the body (10) for connection to electrical circuitry. The array transducer is formed of a composite material in which the pattern of the composite material is oriented at an oblique angle to the kerfs of the transducer.
