The radiation characteristics of the ultrasound transducers can be calculated by means of the concurrent algorithm. This approach is necessary when the calculations are performed on a computer cluster and additionally allows to enhance greatly the overall efficiency of such an algorithm. This paper presents the analysis of radiation characteristic of a few ultrasound transducers obtained by means of the concurrent algorithm. The algorithm bases on the spatial impulse response method and is implemented on an openMosix heterogeneous cluster.
