摘要： Method of improved detection of elements of interest by means of a detection system in a digital radiographic image of an object, acquired on an acquisition chain, comprising a first calibration phase in which the performances of the detection system are established. For such purpose, a calibration curve with several dimensions is determined by means of a mathematical model of the acquisition chain and object, in order to express a false positive probability as a function of a set of parameters corresponding to the acquisition chain and object. In the course of a second phase of use, a false positive probability value is determined for each pixel of the image. One then selects among the pixels of the digital radiographic image acquired those whose probability value obtained satisfies a predetermined criterion.

摘要： The movement of an anti-scatter grid in a radiography apparatus is a continuous curve having point symmetry with respect to the point whose time coordinate is equal to half the exposure time, and for which the space derivative of the time variable has two linear portions which are symmetrical with respect to a symmetry axis passing through the middle of the range of movement of the grid. The grid is moved with a high rate of movement close to the starting position and the end position.

摘要： A method and apparatus for correcting the density of an image in radiography comprising an X-ray source, an image recording placed facing the source, and a support on which an object and surroundings to be X-rayed are intended to be positioned. The method comprises acquiring an image as a mask image; acquiring at least one image as an injected image after injecting a contrast agent into the object to be imaged; and determining corrected images of the mask image and of the injected image from acquisition parameters of the apparatus, from a composition of the imaged object and surroundings and from a composition of the injected contrast agent.

摘要： A method and apparatus for reconstructing an image of an organ or body part from at least two images of the organ or body part taken using radiography in two positions of the organ or body part separated by a rolling movement of the organ or body part. The rolling movement of the organ or body part is determined between two positions, extracting motion vectors for the surface of the organ or body part, interpolating motion vectors between the motion vectors extracted, and reconstructing an image of the organ or body part. The method and apparatus allows the three-dimensional structure of the tissue to be reconstructed while reducing ambiguities due to the presence of a lesion overlaying the tissue.
