摘要： A method and apparatus is provided for detection of a particular material in an object, in particular in an item of luggage, by means of electromagnetic radiation in which the intensities of non-absorbed radiation from at least three radiation planes are measured and evaluated in associated detector apparatus, wherein an image is produced, initially from the intensities of the non-absorbed radiation, and then if single regions of low complexity are found which are characterized by approximately constant intensities, an estimation of the attenuation coefficient s performed and a material detection is carried out in the region according to an algorithm which calculates a three-dimensional reconstruction from different views.
