Abstract
The invention relates to equipment (1) for the radiography of a load (11) moving relative thereto, the radiography equipment comprising a source (2) for emitting pulses (16) of divergent X-rays, a collimator (4) for the source for delimiting an incident x-ray beam (22), and sensors (8) for receiving X-rays, which are aligned with the incident beam so as to collect the X-rays after the latter have passed through the load and generate raw image signals. The equipment includes a reference block (6) comprising intermediate x-ray sensors (28) which are to be located within the incident beam, between the source and the load, so as to be irradiated by at least two separate angular sectors of the incident beam, and which are to output separate reference signals corresponding to each angular sector to be used in the conversion of raw image signals into a portion of a radiographic image. The invention also relates to a corresponding method.
