Abstract: 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.

Abstract: A method, a device, a system and a computer program are for controlling limited-area computer tomography imaging. The method includes determining location data of a first imaging object when the first imaging object is positioned in an imaging area, determining reference location data related to the first imaging object and adjusting the imaging area based on the location data of the first imaging object and said reference location data for imaging a second imaging object. The first and the second imaging object can be located at a distance determined by the reference location data from each other or symmetrically in relation to the reference location data.

Abstract: The present invention relates to a method for producing a three-dimensional digital x-ray image by using digital x-ray images taken of the object from at least two different directions as input for a reconstruction algorithm. In the method, at least one of the images used as input is taken as a tomosynthetic slice image of a region of interest (5) in the object (3) of imaging.
