Abstract
A method for automatically selecting a calculation depth range upon measuring a property of a viscoelastic medium, the depth range being selected from P possible ranges, includes calculating, from the ultrasound signal acquired using a probe for elastography, the property of the viscoelastic medium in at least one of the P depth ranges as well as the distance between the probe and the wall of the viscoelastic medium; determining the validity of at least one of the P calculation depth ranges; determining the validity of the calculation of the property of the viscoelastic medium over the valid calculation depth range or ranges; selecting, from the values of the property of the viscoelastic medium the calculation of which is valid at the valid depth ranges, a depth range fulfilling a selection criterion.
