Abstract:
1. An ultrasound imaging system for forming an echo graphic image of a medium, comprising: a set of transducer elements, which operates in a transmission mode and in a receiving mode for ultrasound waves; construction means for constructing echographic signals on the basis of signals received on said transducer elements; display means, which are coupled to said construction means in order to display an image of the medium formed by means of the echographic signals, said construction means including: determination means for determining an exclusion zone in which at least one coherent reflector is detected; first estimation means for estimating reception delays for the zones outside said exclusion zone; second estimation means for estimating reception delays for the exclusion zones on the basis of delays estimated in the zones outside said exclusion zone; and calculation means for calculating echographic signals on the basis of said estimation delays.
