Summary:An algorithm for estimating the geometrical and phase corrections for receiving–transmitting transducers of a ring antenna array of an ultrasonic tomograph is proposed. These corrections should be taken into account at the stage of the reconstruction of the spatial distributions of the sound velocity and absorption coefficient of an object under study (the breast); otherwise, the quality of the obtained tomograms will deteriorate significantly.
