ULTRASONIC IMAGING METHOD AND DEVICE WITH PREDICTION OF INDUCED ARTEFACTS BETWEEN RECONSTRUCTION MODES

摘要

The invention relates to an ultrasound imaging method for imaging a part (1), characterised by the implementation of the following steps: selecting a first sub-region ({tilde over (Z)}) of the part from a first image (IA(Z)) of a region (Z) of the part (1), determining, for each point of the first selected sub-region ({tilde over (Z)}), the times of flight (TijA({tilde over (Z)})) corresponding to the paths according to a first reconstruction mode (A) going through the point from a transmitter i to a receiver j for a set of M*N transmitter-receiver couples of an ultrasound signal; determining a second sub-region of the part, a point (P) of the region belonging to the second sub-region when a time of flight (TijB(P)) of the path according to a second reconstruction mode (B) going through the point (P) from a transmitter i to a receiver j of said set of M*N transmitter-receiver couples coincides with a time of flight (TA({tilde over (Z)})) of a path according to the first reconstruction mode from a transmitter to a receiver from the transmitter i to the receiver j going through one of the points of the first selected sub-region.
