Zusammenfassung:	A method and apparatus for detecting a discontinuity in the wall of a ferrous object is disclosed, which utilize a bank of sensors where each sensor is configured to detect a difference in magnetic flux across a predefined area. Sets of readings from the sensors are converted to images, from which the existence and location of a discontinuity can be detected. L'invention concerne un procédé et un appareil pour la détection d'une discontinuité dans la paroi d'un objet ferreux, qui utilisent un banc de capteurs où chaque capteur est configuré pour détecter une différence dans un flux magnétique à travers une zone prédéfinie. Des ensembles de lectures provenant des capteurs sont convertis en images, à partir desquelles l'existence et l'emplacement d'une discontinuité peuvent être détectés.
