When processing the echographic image, the whole information contained in the echographic signal is not used. Part of this information related to the complex way in which ultrasound and biological tissue interact is lost through signal analysis. The goal of tissue characterization is the quantitative estimation of acoustic parameters or texture parameters by appropriate signal processing of echographic data. One particularly important parameter which can be estimated is the ultrasonic attenuation and its frequency dependance. Attenuation has been successfully measured in various clinical fields as muscle, liver or breast pathologies.
