摘要： A method for producing an imager includes the following steps: a. attaching an imaging sensor to a first substrate; b. cutting out the first substrate a predefined distance around the attached imaging sensor; c. attaching a driver circuit board for driving the imaging sensor to the cut-out first substrate, close to the attached imaging sensor; d. connecting the driver circuit board for driving the imaging sensor to the attached imaging sensor in order to obtain a first tile; e. repeating the attaching, cutting-out, attaching, and connecting steps in order to obtain a second tile; f. butting together the obtained first tile and second tile by placing the cut-out first substrates in edge-to-edge contact; g. attaching the butted-together tiles to a main substrate; h. connecting the driver circuit boards of the imaging sensors of the butted-together first tile and second tile to a motherboard of the imager.

摘要： A photosensitive sensor includes multiple elementary sensors butted together, each elementary sensor comprising a pixel matrix organized in rows, the pixels of each row being connected to conductors of multiple types, column conductors of which are connected to read circuits of the sensor. The sensor moreover comprises, connected to each of the column conductors, a group of components that is separate from the conductor under consideration, the group of components forming a matching impedance of the conductor under consideration. The impedances in each elementary sensor have the same value and the impedances for different elementary sensors have different impedance values so as to balance the link impedances between the various read circuits and the corresponding column conductors for the various elementary sensors.

摘要： A matrix-array optoelectronic device includes a substrate on which a matrix array of what are called bottom electrodes is deposited; an active structure, which is preferably continuous and organic, arranged above the matrix-array of bottom electrodes, the structure being suitable for detecting light; and at least one what is called top electrode lying above the active structure, the top electrode being transparent to the light emitted or detected by the active structure; and at least one conductive element that is borne by the substrate without interposition of the active structure and that is connected to the top electrode by at least one vertical interconnection, the conductive element having an electrical conductivity greater than that of the top electrode. The device may also comprise a layer made of scintillator material, the layer being fastened to the top electrode, so as to form an x-ray imager.

摘要： A radiology assembly and a method for aligning such an assembly, comprising comprises: an x-ray tube for generating a beam of x-rays that is centered on a main emission direction; and substantially perpendicular to the main emission direction, a planar sensor to receive the x-rays. The radiology assembly comprises: a first divided emitter that is divided into two electromagnetic-field-emitting portions, the emitter being placed so as to emit a first electromagnetic field in a main direction that is substantially perpendicular to the main emission direction, each of the two emitting portions of the divided emitter being positioned on one side of the beam of x-rays; electromagnetic-field sensors that are securely fastened to the planar sensor and that are able to detect the electromagnetic fields emitted by the emitters and to generate a first electrical signal depending on the detected electromagnetic field; and a means for processing the first electrical signal to determine the relative position of the planar sensor with respect to the x-ray tube.

摘要： An electronic read circuit for a radiation detector comprises: an element sensitive to the radiation, an injection circuit, able to inject a charge at one terminal of the sensitive element, the injection circuit extending between at least one input terminal and one output terminal, the output terminal being able to be connected to the sensitive element, the injection circuit being able to produce a charge under the effect of a trigger pulse. The injection circuit is able to inject a first charge when an input terminal is connected to a first input potential and a second charge when an input terminal is connected to a second input potential. The circuit comprises means for storing a difference between an output potential of the injection circuit, called equilibrium potential, and a reference potential, such that the second charge depends on the second input potential and on the equilibrium potential.

摘要： A method for calibrating a digital imager using a sequence of P input images, to which images a calibrating image is applied to obtain a sequence of P output images is provided. The calibration is performed by updating the calibrating image by estimating, in an iteration n, n being an integer higher than or equal to 1, an image representative of the calibrating image.
