A procedure is discussed for improving the quality of the images of flaws on the basis of the practical directivity pattern of the acoustic transducer. This characteristic is taken into account in the reconstruction of images by means of a standard hologram. Results are given to illustrate the efficiency of the method of models of a point flaw and a planar flaw. The transverse resolution is improved by a factor of 1.7.
