4D DATA ULTRASOUND IMAGING SYSTEM AND CORRESPONDING CONTROL PROCESS

摘要

4D data ultrasound imaging system (100) comprising a matrix (10) of transducer elements (3) suitable for transmitting and for receiving ultrasound signals, said transducer elements (3) being divided into sub-matrixes (21) suitable for receiving in a delayed way a same acoustic signal, a plurality of reception channels (22) with one of said reception channels (22) being associated with one of said transducer elements (3), a beamformer device (109) comprising a plurality of storage cells (111) arranged in re-phasing matrixes (112), each re-phasing matrix (1 12) being associated with a corresponding sub-matrix (21) with each row (Ri) associated with one of said transducer elements (3), said storage cells (111) comprising an input storage stage (In) that is selectively associated with a row (Ri) and a reading output stage (Out) that is selectively associated with a buffer (16); each storage cell (111) that belongs to a same column (Coi) has the input stage (In) that is dynamically activated in sequential times with respect to another storage cell (11 1) of the same column (Coi) for storing the same delayed acoustic signal, said storage cells (1 11) that belong to the same column (Coi) have the output stage (Out) that is simultaneously activated.
