Abstract
A compression method is presented for medical images based on neural n etworks and vector quantisation (VQ). The neural net is a perceptron a nd it is followed by some expressly designed VQ algorithms. The method devotes special attention to the quality of the reconstructed images and to the reduction of artefacts. The compression ratio obtained in t he long run with echographic images is greater than 50:1 with good qua lity.
