The invention relates to equipment () for the radiography of a load () moving relative thereto, 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 (), and sensors () 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 () comprising intermediate x-ray sensors () 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.

Equipment for the radiography of a load, comprising a reference block, and associated method

A radiographic imaging method for three-dimensional reconstruction in which the three-dimensional shape of a model representing an object is calculated from a geometrical model of the object that is known a priori, and obtained from a confinement volume of the object estimated from a geometrical pattern visible in two images and from knowledge of the positions of the sources. A geometrical model is used that comprises information making it possible using an estimator for the object to establish a geometrical characteristic for the model representing the object.

Two-dimensional detector of ionizing radiation and process for manufacturing this detector This detector comprises sheets () emitting particles by interaction with ionizing radiation, semiconducting layers () that alternate with the sheets and can be ionized by the particles, and groups of conducting tracks () in contact with the layers. Means () of creating an electric field are used to collect charge carriers generated in the layers due to interaction with particles, through the tracks. For example, the layer and the corresponding tracks are formed on each sheet and the sheets are then assembled together. For example, the invention is applicable to radiography and can achieve good X-ray detection efficiency and high spatial resolution at the same time.
