ABSTRACT:
In the method are repeated the stages of: exposing (6) a zone of a sample to the X-rays through a collimator, exposing only the parts of the sample placed between it and some secondary boards of a main board; obtaining (7) the data generated by exposure of the sample; and moving (8) the mobile support to another zone of the sample. Next, the data to obtain a complete digital image are processed. The device comprises a source of X-rays, a data-gathering device, a detection module which has a main board upon which are arranged secondary boards, a collimator fitted between the main board and the source of X-rays; and a unit for processing the data. A continuous image without size limitation is obtained.
