Abstract: An embodiment of a 4D data ultrasound imaging system includes a matrix of transducer elements suitable for transmitting and for receiving ultrasound signals, said transducer elements being divided into sub-matrixes suitable for receiving in a delayed way a same acoustic signal, a plurality of reception channels with one of said reception channels being associated with one of said transducer elements, a beamformer device including a plurality of storage cells arranged in re-phasing matrixes, each re-phasing matrix being associated with a corresponding sub-matrix with each row associated with one of said transducer elements, said storage cells including an input storage stage that is selectively associated with a row and a reading output stage that is selectively associated with a buffer; each storage cell that belongs to a same column has the input stage that is dynamically activated in sequential times with respect to another storage cell of the same column for storing the same delayed acoustic signal, said storage cells that belong to the same column have the output stage that is simultaneously activated.
