Abstract
A method and device of scanning objects by means of ultrasound echography by repeated transmission of ultrasound signals and the reception of the ultrasound echoes includes the following operations: PA1 (a) storing an echographic line in a memory; PA1 (b) determining the ratio of the power spectra for two distinct observation depths, including correction for the effects of the diffraction; PA1 (c) storing in a memory and/or displaying the frequency-dependency of the scatter function of the object examined; PA1 (d) repeating the proceding operations for two other observation depths which correspond to resepctive boundaries of homogeneous zones, and for other echographic lines.
