Abstract
Frequency-dependent attenuation is one of the most marked features of wide-band ultrasound pulse propagation in human soft tissues. Specification of the functional dependence of the attenuation on frequency (in the diagnostic frequency range) is, to a large degree, a matter of choice - the most favoured being a simple power law, with non-integral index. In that case. there are two parameters which characterise the attenuation, and the values of both of these (or their progressive changes with disease) are widely regarded as conveying some information about the pathological state of the tissue.
