Contemporarily, vast amounts of wood are going into paper production. As a consequence, different qualities of wood are selected appropriately for the various applications. Beams incorporated into buildings and constructions have to be sturdy and durable; boards for furniture are supposed to be free of knots or are expected to have certain ornamental structures. As long as wood is not simply destined for burning it should be free of undesired knots or internal damages such as rot or worm holes. Particularly in cases of infestation with wood destroying fungi that definitely impairs mechanical strength and even may generate hollows such damages are frequently invisible from the outside. Radiographic methods are capable to detect internal damages as well as hidden knots without the need of drilling holes or cutting a specimen to pieces. The most thoroughly method to visualise the interior of a wooden specimen is tomography which shows annual growth rings in their complete circumference and all the knots or damages that might be included. However, some of them as well as patterns of annual rings suitable for dendrological investigations are recognisable with a less laborious method that might be applicable even in the field, i.e. contemporary digital radiography combined with image processing. Samples of lumber shall be presented showing the typical annual ring structures and some infested areas.
