Abstract
Abstract A device for producing two- and/or three-dimensional images of three-dimensional objects, comprises at least two radiation sources, a detector arrangement, a computer, a processor and a display device, in which a number of radiation sources are arranged on a straight line, the detector device consists of a plurality of detector elements arranged in a plane parallel to the straight line, and means are present to process the signals which can be derived from the detector elements and to supply them to the computer.
