Abstract: A medium of interest is interrogated according to ultrasound elastography imaging. A preliminary elasticity-spatial-map is formed. This map is calibrated against a reference elasticity-spatial-map that comprises an array (232) of different (240) elasticity values. The reference map is formed to be reflective of ultrasonic shear wave imaging of a reference medium. The reference medium is not, nor located at, the medium of interest, and may be homogeneous. Shear waves that are propagating in a medium are tracked by interrogating the medium. From tracking locations on opposite sides of an ablated-tissue border, propagation delay of a shear wave in the medium and of another shear wave are measured. The two shear waves result from respectively different pushes (128) that are separately issued. A processor decides, based on a function of the two delays, that the border crosses between the two locations.
