Abstract
An integrated approach for the absorption of ultrasound by liquids and tissues is proposed from the solution of a one-dimensional wave equation of propagation. The proposed model explains the square and linear power dependence of absorption on frequency for liquids and tissues, respectively. The study also provides a new index, specific heat ratio (y), in terms of which the physical and the chemical state and thus possibly the pathological state of a tissue can be defined quantitatively.
