Combined X-ray Diagnostics of Heterogeneous Biological Material

The problem of flnding a suitable diagnostic procedure for the examination of structural components of buildings has been closely analyzed in recent years. In this connection, the major interest is currently directed towards wood as a type of heterogeneous material; the utilized diagnostic procedures are under constant development to enable broad industrial ap- plication in the future. Within the research presented in this study, a new diagnostic method based on X-ray imaging has been proposed and tested. The technique utilizes the reduction of imaging information into 2D/3D planar projection, and it allows us to image clearly the rate of material damage by displaying the weighted damage rate. Another method is based on acoustic identiflcation of structural elements infest ed with wood-destroying insects.
