1. A method for measuring features of an object to be imaged using an ultrasound probe, the method comprising the following steps of:
executing, with the ultrasound probe, two or more iterations of the following steps of:
i. transmitting, with the ultrasound probe, an ultrasound field having an aperture with a given size;
ii. receiving, with the ultrasound probe, an echo of the ultrasound field following reflection on a zone of interest of an object to be imaged;
iii. modifying, for each new iteration, the size of the aperture of the ultrasound field;
recording, for at least one point of interest in the zone of interest, an associated time-of-flight on the received echo;
determining, a variation model of recorded times-of-flight as a function of the size of the aperture of the ultrasound field;
extrapolating the time-of-flight of the at least one point of interest for a value of an aperture size tending towards 0 based on said model.
