摘要： A method for the real-time control of exposure to an X-ray dose emitted by a generator tube for generating an X-ray beam and received by a detector includes a flat panel detector, comprising a set of pixels organized into a matrix along rows and columns and configured so as to generate signals on the basis of the X-ray dose impinging on the detector, the generator tube comprising a control unit for controlling the generator tube that is configured so as to control an emitted X-ray dose, the control method comprising the following steps: exposing the flat panel detector to an X-ray dose emitted by the generator tube for generating an X-ray beam; repeatedly reading out at least one of the rows of pixels while the flat panel detector is exposed to the X-ray dose; determining a payload signal and a stray signal based on the signals from the readout of the at least one of the rows; transmitting the payload signal to the control unit for controlling the generator tube.

摘要： A matrix-array detector includes an array of pixels that are sensitive to a physical effect and arranged in a matrix along rows and down columns, each pixel generating a signal according to the physical effect; row conductors, each allowing the pixels of one row to be driven; driver modules delivering selection signals to the row conductors, the driver modules being configured to deliver signals according to either of two levels, one being a high level allowing one of the rows of pixels to be selected and the other being a low level not allowing it to be selected. The detector further comprises impedance modules that are connected to each of the row conductors and configured to decrease the impedance of each row conductor and to keep the impedance of each row conductor low in a phase of reading the array of pixels as long as the corresponding selection signal is at the low level, the impedance modules being separate from the driver modules.

摘要： A method for reading an imaging device intended for capturing images in a detector including a large number of photosensitive points called pixels organized into a matrix. The pixels of the same column are linked to a column conductor enabling the successive reading of the photosignals acquired by the pixels of the column, the method consisting for each of the pixels in carrying out a correlated double sampling read phase, the read phase comprising an operation of resetting the pixel followed by two read operations, the first without the photosignal, and the second with the photosignal. Three steps are concatenated in succession for the pixels of the same column: 1. a first of the operations of reading the pixel of a first row, 2. one of the operations of reading a second row, 3. a second of the operations of reading the pixel of the first row.

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.
