Abstract
Digital radiography is a very useful tool in nondestructive evaluation. However, single radiographic projection contains information about the potential defect only in two dimensions. Thus, the defects may be overlapped or placed parallel to the X-ray beam. We present how a simple, low-cost extension of an existing radiographic system may increase its capability so that it is possible to localize objects in three dimensions. The presented methodology is based on approximate three-dimensional reconstruction from few projections and depth identification procedure. The proposed method also increases detectability of the potential defect.
