Abstract: An ultrasonic imaging device includes a plurality of ultrasonic transducers arranged in rows and columns. Each transducer has a lower electrode and an upper electrode. In each row, any two neighboring transducers of the row respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other and in each column, any two neighboring transducers in the column respectively have their lower electrode and their upper electrode connected to each other, or their upper electrode and their lower electrode connected to each other.

Abstract: An ultrasound imaging device includes an assembly of ultrasound transducers. The ultrasound transducers are divided into a plurality of sub-assemblies each having P ultrasound transducers. The ultrasound imaging device further includes, for each sub-assembly, K transceiver circuits and a configurable routing circuit coupling the P ultrasound transducers of the sub-assembly to the K transceiver circuits where P and K are integers greater than or equal to 2, with K smaller than P. Each sub-assembly further includes at least one mobile transducer capable of being, via the routing circuit, disconnected or connected to any one of a plurality of predefined transceiver circuits among the K transceiver circuits of the sub-assembly.

Abstract: An ultrasonic imaging device includes a plurality of ultrasonic transducers arranged in an array of a plurality of rows and a plurality of columns, the array being divided into a plurality of sub-arrays of neighboring transducers, each including a plurality of rows and a plurality of columns, the device including, for each sub-array: a single transmit and/or receive circuit; and a combiner selector and/or splitter selector circuit configurable to couple any, alone, of the transducers of the sub-array to the transmit and/or receive circuit of the sub-array, or to simultaneously couple a plurality of the transducers of the sub-array to the transmit and/or receive circuit of the sub-array. The device further includes a control circuit adapted to individually controlling the combiner selector and/or splitter selector circuits of the different sub-arrays.

Abstract: An ultrasound imaging device includes a plurality of ultrasound transducers arranged in an array of rows and columns. Each of the transducers has a first electrode and a second electrode. The first electrodes of the transducers of a same row are interconnected and the second electrodes of the transducers of a same column are interconnected.
