Paper Abstract

The aim of this study was to discover possibilities for using x-ray radioscopy in thin wood inspection. The main goal was to find a suitable x-ray imaging method to define the variations in wood density. In x-ray imaging radiation is sent through an object where radiation weakens proportionally to the object's thickness, density and moisture content. By sensing differences in attenuation an image can be created, allowing for the study of these properties. Because x-rays can penetrate deeply, x-ray imaging can be used for various materials and for many different imaging applications. The energy level of x-ray must be fairly low when imaging thin wood, as the level of attenuation is low due to the wood's thinness and low density. Some different imaging devices were tried in order to find suitable method for the task, and the best quality images were obtained with a mammography x-ray device. Digital out processing was used to enhance image contrast and density variations, respectively.
