Abstract :
An extended radiography system for identification of defect position in three dimensions is presented. We propose the use of limited angle reconstruction algorithms combined with a procedure for determining the depth of the object, thus partially recovering the third dimension from limited set 2D X-ray projections acquired along linear trajectory.
