• In order to determine the size of the vibrating surface of an individual element and the spaces among elements in a cylindrically arrayed ultrasonic transducer, enormous calculations for mutual- and self-radiation impedances should be accomplished within a limited time. However, the direct application of the equation of Greenspon and Sherman to such numerical calculations requires a very long time to obtain high accuracy. In this study, an effective calculation algorithm was investigated by introducing subintervals into the integration of the Greenspon and Sherman's equation. As results, limits of subintervals improving computation time and accuracy were fitted as functions of the size of the vibrating surface of the element and the size of the baffle.
