ABSTRACT:
A bi-plane phased array transducer for real time medical imaging having a composite piezoelectric disk with an array of transducer-element electrodes disposed on each major surface of said disk, the array on one side being at an angle to the array on the other side and electrical connections to ground each array alternately so that real time sector imaging in two planes is obtained.
