The paper presents the physical base of the numerical system for analysis and modelling acoustic fields generated by an acoustic head of arbitrary construction. The elaborated system allows to analyse the sending-receiving multielements ultrasound heads. In the paper modeling of the acoustic system as the linear one was proposed. Numerical model, its implementation and preliminary results was presented.
