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.
Keywords: Digital radiography, image reconstruction, defect detection
