Radiological imaging device comprising an emitter of an X-ray beam and a receiver of the X-ray beam after it has crossed an organ, the organ being capable of being placed between the receiver and a compression element, capable of being removably fixed on the device. A calculation unit includes a means for optimizing the image quality over a particular area defined by the compression element.

Radiological imaging device, method and program of control associated with the device

A collimator for X-ray apparatus has an aperture defined by the edges of four movable flexible shutters. Each shutter can be moved independently of the other shutters; thus, the position and the size of the aperture can be adjusted at will. The shutters are moved by winding them onto drums; each drum is driven by a stepping motor. Springs bias the shutters towards the closed position of the collimator.

Adjustable collimator and method

Method and apparatus for a radiographic image of an object obtained by a radiography apparatus containing an X-ray emitter, in which an anti-scatter grid placed between the object and a radiographic image receiver is displaced, on rectilinear translation in its plane, when acquiring the images, between a starting position and an arrival position, according to a time displacement law of reference, at a greater rate of displacement in proximity to a starting position and to the arrival position. A measurement of the energy received in the form of X-radiation by the receiver is used to modify the rate of displacement of the grid at every instant.

Method and apparatus for obtaining an image by radiography with an anti-scatter grid

Device for taking radiologic images, of the type comprising a means of emission of an X-ray beam and a means of reception of the X-ray beam after it has passed through an organ to be studied. The means of emission and the means of reception are supported by an arm pivoting about at least one shaft supported by a frame. The device comprises a means for detecting the angle of swivel of the arm, a means for entering data relative to the organ to be studied, a processing means capable of determining the type of image that will be taken as a function of the angle of swivel and of the said data relative to the organ, and a means for displaying on the image the type of image determined by the said processing means.
