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