Annotation

Algorithm of estimating the geometrical and phase corrections for receiving–transmitting transducers of ring antenna array of ultrasound tomograph is discussed. These corrections should be taken into account during reconstruction of spatial distributions of sound velocity and absorption of an investigated object, in order to avoid a deterioration of tomogram quality.
