Abstract (en)
Apparatus for calculating the delay coefficients to be used for the transducer of a linear array at successive focal points along each radial line of a sector along which ultrasonic pulses are transmitted comprising a plurality of clocked accumulators connected in series (AC3,AC2,AC1) said accumulators being preloaded with appropriate combination of the coefficients of the successive terms of a series expressing an approximation of the formula, D = R - 2ROOT (X-Xo)<2> + Yo<2> where R is the distance of a focal point from a given point in the sector, X is the number of the accumulator from the origin and Xo, Yo are the coordinates of the focal point.
