Abstract: A radiology assembly includes an x-ray tube for generating a beam of x-rays that is centered around a main emission direction, a planar sensor extending in a plane defined by a first direction and by a second direction, which directions are substantially perpendicular to the main x-ray emission direction, the sensor being intended to receive the x-rays, comprising a first divided emitter that is divided into two electromagnetic-field-emitting portions; a second divided emitter that is divided into two electromagnetic-field-emitting portions; a so-called planar electromagnetic-field emitter, electromagnetic-field sensors that are securely fastened to the planar sensor, a processing means intended to determine an angle of alignment between the main emission direction and a normal of the planar sensor, to determine a first centering error and a second centering error, a correcting means for correcting the angle of alignment by applying a first corrective movement to the x-ray tube and first and second centering

Abstract: A digital detector includes a conversion block intended to convert incident radiation into electric charge; an electronic card that converts the electric charge into a digital image, the conversion block comprising N conversion stages superposed on one another, N being an integer between 2 and M, each of the N conversion stages comprising: a monolithic substrate; a first converter assembly in the form of a polygonal matrix array, M being the number of sides of the polygonal matrix array, M preferably being equal to 4, and configured so as to generate the electric charge on the basis of the incident radiation; an addressing and driving module for addressing and driving the matrix array, the addressing and driving module being arranged on the monolithic substrate along one side of the polygonal matrix array; each of the N conversion stages being oriented by at least 1/M of a turn with respect to the other N?1 conversion stages of the conversion block, and with an orientation distinct from the other N?1 conversi

Abstract: A solid-state radiation detector comprising a photosensitive sensor comprises photosensitive elements that are organized in a matrix, and a light generator whose purpose is to optically wipe the photosensitive elements. The light generator comprises: an electroluminescent layer that is distributed over the surface of the sensor; at least one electrode that continuously covers the electroluminescent layer and in which electrons may flow, the light emitted by the electroluminescent layer being capable of passing through the electrode; and additional electrical conductors that are in electrical contact with the electrode, the additional electrical conductors forming branches that extend over the surface of the electrode, and being spatially distributed across the surface of the electrode.

Abstract: A solid-state X-ray detector comprising a photosensitive sensor combined with a radiation converter or scintillator is described. The radiation detector includes an entry window through which the X-rays upstream of the scintillator pass, and means for applying an electrical voltage between the entry window and the photosensitive sensor.
