ABSTRACT
There are fields in the wood industry where the sawn timber have to suit exacting requirements. In these cases, the conventional X-ray examination gives only a poor information. The CT as a Nondestructive Testing Method got used for decades in medical fields but less for industry. Especially in Hungary the CT in industry hasn't yet became a routine examination. According to the theoretical assessments the medical CT can be used in the forest products industry without any significant modification of the apparatus. Therefore pilot studies have been introduced by a co-operation between the Wood NDT Laboratory of the University of Western Hungary and the local City Hospital "Erzsebet". The type of the medical CT used was a Picker PQ2000 CT scanner. For the test experiments of logs we chose the following three species of woods: oak, fir and birch. The most significant advantage is that the longitudinal section of the material can make visible which information has been lost in the former examinations. The first investigation performed gave a positive experience in the use of medical CT to qualify the wood logs and to get information from the internal structure of the wood. The sizes of the knots and the cracks of the wood are easy to identify. Our first experience m the use of CT m forest products industry promoted the extension of similar investigations.
