Abstract
An improved biplane phased array transducer for real time medical imaging in at least two sector planes having a composite piezoelectric plate with an array of transducer elements disposed on each major surface of said plate, the array on one side being at an angle to the array on the other side, said transducer elements being defined by dicing each major surface of said composite plate through the conductive electrode surface and into a portion of the composite piezoelectric material, and electrical connections provided whereby each array may be grounded alternately so that real time sector imaging in two planes is obtained.
