(57) An X-ray device and method that can be used to generate digital images in which the use of passive selection devices that utilize the principle of diffraction and/or reflection makes it possible to select a part of the spectrum emitted by a radiogenic tube and thus transmit an X-ray beam characterized by a restricted energy band.
