Abstract: The invention relates to a tomosynthesis process in the context of mammography, in which several individual images of a breast are taken at different projection angles and in which of information thus acquired, tomographic images are synthesized with the help of an applicable image processing software. The mutual geometry of the imaging means of the imaging apparatus when taking these individual images is determined according to the invention by arranging in the imaging apparatus a calibration structure (20), which includes balls (21) or other small objects absorbing X-radiation which are such placed that their projections will become imaged on said individual images.

Abstract: The invention relates to positioning of partial volumes of an anatomy in connection with an imaging process. According to the invention, a photograph is taken of an object arranged in an imaging station by a camera arranged in connection with the imaging station, which image of the anatomy is presented on a display but as transferred into a new position with respect to the imaging station. When this image and a substantially real time image taken of the imaging station are presented on a display one upon another, it is possible to follow on the display how the object being imaged positions in relation to said image taken of the anatomy transferred into the new position.
