Abstract: A grid of phased array transducers includes a piezoelectric layer and a plurality of ground contact traces. The piezoelectric layer includes a first side and a second side. The plurality of ground contact traces is disposed on the first side of the piezoelectric layer along an elevational direction, where each ground contact trace of the plurality of ground contact traces extends along an azimuthal direction. Further, each phased array transducer of the grid of phased array transducers is disposed between an adjacently disposed pair of ground contact traces of the plurality of ground contact traces. Moreover, each phased array transducer includes at least a portion of at least one ground contact trace of a corresponding pair of ground contact traces, and where each phased array transducer includes a plurality of transducer elements.

Abstract: A transducer probe is presented. The transducer probe includes a housing having a probe surface at a first end. Further, the transducer probe includes an acoustic array having an array aperture, wherein the acoustic array is disposed adjacent the probe surface of the housing, and wherein the acoustic array is configured to transmit ultrasound signals towards a target volume. Also, the transducer probe includes a flex interconnect configured to electrically couple the acoustic array to at least one electronic unit. Furthermore, the transducer probe includes an electrical standoff disposed between the acoustic array and the flex interconnect to reduce a footprint of the transducer probe to a first value, wherein the first value is proximate to a lateral size of the array aperture.
