A method for the detection of a specific material in an object (), especially in a piece of luggage, using electromagnetic beams, whereby the intensities of non-absorbed beams from at least three beam planes () in corresponding detector arrays () are measured and evaluated, using the following steps according to the invention: 1. generating an at least two-dimensional picture of the object () from the measured intensity values; 2. selecting one of the spatial regions displayed in the picture as a basis of the value of a material value, which is determined from intensity measurements, for examination; 3. determining at least one spatial-geometric value in the region to the examined from positional data of a two-dimensional picture and from intensity values using a stored value of a specific, absorption-influenced value of a suspected material. 4. determining, in addition, the corresponding spatial-geometric value solely from three-dimensional geometric values, which are determined from measured intensity values; and 5. comparing, directly or indirectly, values of the spatial-geometric values determined in steps 3 and 4, or values derived therefrom, in order to determine if the suspected material is actually present.

A method for image management of X-ray images stores the images in files along with reduced-size versions of the images and additional information relating to the images. A user may preview each image in a reduced-size display, based on the reduced-size image, which preview may also include the additional information. The image may then be selected from the display for complete display of the original image.
