Ultrasonic velocity and attenuation in mammalian tissues

Abstract
A compilation, from original papers, is presented of data on acoustic properties (i.e., velocity and attenuation) of mammalian tissues in the megahertz range of frequencies used in medical ultrasonics. Actual values reported were quoted to present a clear picture of the current state of knowledge in order to enable it to be assessed and to enable future workers to compare their own results directly. In the 20 yr since the last such compilation, progress in estimating relative contributions of the animal species, condition of the tissue, temperature and frequency at which measurements were made and method of measurement to the observed variation has been small.
