ABSTRACT:
A method of imaging for enhancing detection of cracks or flaws in an object using penetrating radiation is disclosed wherein a contrast medium is applied to an object before illumination and scatter radiation is detected from the object. This is achieved by employing a flying spot scanner and a backscatter imaging technique allowing imaging of objects which are not completely accessible, e.g. imaging the object where only one side accessible.
