摘要： In an apparatus for radiographic projection tomography, particularly mammography, an X-ray tube is mounted at the end of a swiveling arm, with a relative movement mechanism. The relative movement mechanism is such that it enables the tube to follow a path of a cycloid. Images or exposures taken only during the time when the tube, in its path, follows cusp points such that it is possible to keep a constant speed of movement of the arm while at the same time increasing the useful duration of an image. Vibration or oscillation effects inherent in the apparatus are compensated by the positioning, if necessary, of a counterweight.

摘要： In a method for the obtaining a tomosynthesis image for a more selective detection of radiology signs, a dose distribution strategy is proposed. The strategy is defined as a function of a substantially uniform depth-of-focus for a variety of sizes and classes of radiology signs. This strategy is coupled with a digital filtering aimed at ensuring optimum propagation of the signal-to-noise ratio beyond the frequency spectrum. This digital filtering is done by means of a class of adaptive filters required to control the propagation of the noise during the reconstruction. The filter to be applied to each projection of the X-ray tube (4) depends on the dose assigned to this projection.
