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.

Abstract: The present invention relates to 3D mammography, in which individual images of a breast are taken at different projection angles and a 3D image subsequently synthesized from this image information. According to the invention, a breast to be imaged is arranged locked in a locking means (16, 17) and during the imaging process, the x-ray source (13) is continuously moved with respect to location of the breast and the breast is irradiated at a number of angular positions of the x-ray source (13).
