Popis:	This paper describes a simple simulation of the signal pathway in an ultrasonic A-scan. It includes transient diffraction acoustic field, transducer response, and frequency dependent absorption in the field medium. The approach selected here aim to develop digital computer simulations of the physical processes that underlie these effects. The soft tissue is considered as a viscoelastic medium and the relaxation theory has been used to calculate the absorption data and dispersion in the tissue. The simulation is used to estimate the degradation in range of resolution due to wave absorption.
