摘要：
Original spatiotemporal signal processing algorithms have been developed to improve the reliability of ultrasonic testing of unique antique cast bronze articles. In particular, to inspect large bells on the grounds of the Moscow Kremlin, with numerous relief images that limit the surface available for mounting piezoelectric transducers, various spatiotemporal signal processing algorithms have been designed, including the ones based on rotating a double-crystal transducer with the summation of partial defectograms.
