ABSTRACT:
A method of scanning objects by means of ultrasonic echography, including the transmission of ultrasonic waves to the object to be scanned by means of a transducer array (101) and the reception and processing of the echographic signals corresponding to the echoes returned. Digitized A-lines are divided into n elements of p points and, after various operations, the reconstruction of the elements of the echographic lines by selection of principal vectors which imply factors which imply a reconstruction of the matrix sum of the series of unity matrix products relative to said selected principal vectors.
