Abstract
A method for characterizing a tubular object by ultrasonic imaging includes: acquiring a plurality of ultrasonic signals originating from the reflection of an ultrasonic field transmitted by the transducer in a region of interest in a transverse cross-sectional plane of the object, for different positions of the transducer relative to the region, all of the ultrasonic signals forming an ultrasonic image of the region; for each signal corresponding to a vector of the image, applying a predetermined first filter to the signal; selecting, from all of the signals, the signal for which the result of the filter contains the extremum with the highest absolute value, and plotting the abscissa of this extremum; and determining the centre of the object from the abscissa plotted and the velocity of the ultrasonic signal.
