1. A method of detecting a defect in an object, comprising:

  • obtaining ultrasound scan data derived from an ultrasound scan of the object under consideration, the ultrasound scan data being in a form of a set of echo amplitude values representing amplitude of echoes received from the object during ultrasound scanning at certain spatial and temporal points;

    processing the ultrasound scan data to remove echo amplitude values received after a predetermined threshold time;

    generating at least one image from the processed ultrasound scan data;

    subjecting the generated at least one image to an automated defect recognition process to determine whether there is a defect in a portion of the object represented by the image;

    issuing a notification indicating whether a defect has been found; and

    storing, provided the defect has been found, a result of the automated defect recognition process in a defect database.
