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.

Abstract: A mammography apparatus has a bracket having one of its arms fitted with an X-ray tube head. The X-ray tube head is formed of an X-ray tube for producing X-radiation and a collimator for collimating the X-radiation. The bracket arm opposite the X-ray tube head is fitted with an image forming element. The bracket is further provided with a compression means for compressing a breast during an imaging procedure. The image forming element has a digital full field detector. The mammography apparatus has integrable therewith a biopsy device with a biopsy needle. The detector required in a biopsy imaging process for imaging the volume space of biopsy is formed of a desired element of the full field detector. A needle guiding unit is provided for a guided movement of the biopsy needle in the volume space of biopsy on the basis of three-dimensional information compiled in the biopsy imaging process.
