An ultrasonic monitoring system is formed with a probe unit. In one example an array of transducer cells is arranged in rows and columns formed along a first plane with a first pitch along a first direction. An integrated circuit including an array of circuit cells is formed along a second plane parallel to the first plane. The circuit cells are spaced apart along the first direction at a second pitch smaller than the first pitch. A first of the transducer cells is vertically aligned, along a direction normal to one of the planes, with a first of the circuit cells and having a connection thereto. A second of the transducer cells is offset from vertical alignment with respect to the position of a second circuit cell so as to not overlie the second circuit cell. A connection subsystem is positioned between the array of transducer cells and the array of circuit cells, configured to form connection of the first transducer cell to the first circuit cell and connection of the second transducer cell with the second circuit cell.

An ultrasound monitoring system. In one embodiment, an array of transducer cells is formed along a first plane and an integrated circuit structure, formed along a second plane parallel to the first plane, includes an array of circuit cells. A connector provides electrical connections between the array of transducer cells and the array of circuit cells, and an interconnection structure is connected to transfer signals between the circuit cells and processing and control circuitry. The integrated circuit structure includes a semiconductor substrate and a plurality of conductive through-die vias formed through the substrate to provide Input/Output (I/O) connections between the transducer cells and the interconnection structure. The monitoring system may be configured as an imaging system and the processing and control circuitry may be external to the probe unit.
