A system comprising a probe comprising a flexible substrate including signal lines; and a plurality of tiles each coupled to the flexible substrate, each tile (300) of the plurality of tiles including: a plurality of piezoelectric transducer elements (310); and a base (305) supporting the plurality of piezoelectric transducer elements on a first surface of the base. The base includes an integrated circuitry comprising a control logic (350) to configure a respective first operational mode (S1) of a tile; a pulse logic (320) to activate, in response to the control logic, a selected subset of the plurality of piezoelectric transducer elements; and a demultiplexer logic (340) to receive image information based on the activation of the selected subset of the plurality of piezoelectric transducer elements and, based on configuration of the respective first operational mode, to demultiplex the image information for transmission from the tile to the flexible substrate.
