Abstract
A transducer useful for medical imaging ultrasonic transducers comprises a front impedance matching layer, a piezoelectric array, and a rear layer. The front impedance matching layer may include a return connection region electrically coupled to a distal end of the piezoelectric array and a front metal layer with a return signal portion for routing the return signal from the distal end of the transducer to a flex circuit of the rear layer at a proximal end of the transducer. In an embodiment, the rear layer may include a return connection region that is electrically coupled to the piezoelectric array at a distal end of the transducer and also electrically coupled to the signal return lines of a flex circuit at the distal end of the transducer.
