Annotation
Algorithm of estimating the geometrical and phase corrections for receiving-transmitting transducers of ring antenna array of ultrasound tomograph is proposed. These corrections should be taken into account at the stage of reconstructing the spatial distributions of sound velocity and absorption coefficient of an investigated object (breast). Otherwise, a quantity of obtained tomogram significantly deteriorates.
