Abstract

The new x-ray arrangement for the radiography of large objects, eliminates the disadvantages of the x-ray arrangements used today, namely the image distortion, and the need of high x-ray energy, and considerable radiation protection. The arrangement allows the creation of a simplified form of tomography and 3-D images. The arrangement consists of a movable, scanning x-ray emitter characterized firstly by the fact that the target of the electronic beam is movable, and may be moved according to a predetermined, regular moving pattern along the lengthened anode, secondly by the fact that the x-ray emitter is placed near the object. The emitted radiation bundle is collimated with the help of one or more rotating, cylinder-shaped collimators encircled by a symmetric slit along the cylinder of each collimator for the x-ray beams to be parallelly scanned through the object. By using two or more coolimators in co-operation the image quality may be varied steplessly in connection with the production of images. The movable x-ray emitter may also be used in co-operation with other types of collimators than those described above to generate divergently scanning x-ray beams through the object or for radiographing objects without collimator or collimators.
