EQUIPMENT FOR THE RADIOGRAPHY OF A LOAD FOR PERFORMING DETECTION, AND ASSOCIATED METHOD

摘要

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 the 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 the raw image signals into a portion of a radiographic image. The invention also relates to a corresponding method.

1. Equipment for the radiography of a load in order to perform detection, the equipment and the load being designed to move relative to one another during the detection, the radiography equipment comprising:
a source for emitting pulses of divergent X-rays; a collimator for the source for delimiting an incident X-ray beam designed to irradiate a section of the load, the successive X-ray pulses being capable of irradiating successive sections of the load; and sensors for receiving X-rays situated in the extension of the incident beam to receive the X-rays after they have passed through the load and generate raw image signals designed to be converted into a radiographic image portion corresponding to said section;wherein it further includes a reference block including intermediate X-ray sensors which are to be located each, at least partially, in the incident beam, between the source and the load, the intermediate sensors being designed to be irradiated by at least two separate angular sectors of the incident beam and to provide independent reference signals corresponding to each angular sector to be used in the conversion of the raw image signals into a portion of the radiographic image.
