DEVICE FOR GENERATING DELAYS FOR BEAM SYNTHESIS APPARATUS

摘要

The invention concerns a device which consists in storing in three tables (5, 6, 7), for each of the transducer elements of an ultrasound probe, reception time reciprocal values (1/t-tau∞.), offset values (tau∞) and corresponding indexes (ND), and values (Delta<2>) which are a function of the square of the distance of the element K concerned to the central reference element, and in calculating the delay tauK(t) to be applied at time t to said element in accordance with the formula (I).
