Spectral 'noise' and ultrasonic tissue characterization.
The spectral fluctuations of each realization of echo signals are usually regarded as a noise to be rejected. However, a significant amount of texture information is hidden within such 'noise'. In fact, it allows us to distinguish three classes of breast tissue, chosen for their distinctive histology.
