Abstract

The measurement of shear wave velocity in biological tissues delivers much information on the tissue state and its structure. It may be used in diagnosis of different tumors. Such measurements involve some difficulties; for instance a transducer is necessary, which radiates pure shear waves into the tissue and does not generate longitudinal wave components. The possibly excited longitudinal waves, the attenuation of which is essentially lower than that of shear waves, may disturb the shear wave measurements, and for this reason longitudinal waves are highly undesirable.
