摘要: A system (1) for the detection of defects in rails (12), comprising a source ultrasonic waves emitting onto rail, detector detecting reflected or otherwise scattered by rail therein and mist generator (3) arranged, use, to expose one both liquid, thus enabling formation an ultrasound-transmissive interface between waves.
