Popis:	This paper describes a simulation of signal pathway in an ultrasonic A-scan. It includes transient diffraction acoustic field, transducer response, absorption and dispersion in viscoelastic medium with arbitrary distribution function. The approach selected here aims at developing digital computer simulation of the physical process that underlies these effects. The soft tissue is considered as a viscoelastic medium, and the relaxation theory has been used to calculate the absorption and dispersion data in the tissue. A signal processing technique is developed in this paper to estimate the degradation in range of resolution due to wave absorption.
