Abstract: The invention relates to an arrangement and method in digital mammography imaging especially for use for imaging of small breasts. In the invention, a so-called full-field sensor and an upper compression plate substantially equal in width with this sensor are used. According to the invention, the beam is limited to a width narrower than the width of the sensor and the compression plate and directed for oblique imaging non-centrally relative to the center of said sensor and the upper compression plate, while the automatic exposure system of the imaging apparatus is caused to adapt itself for imaging in accordance with this imaging position non-central relative to the sensor and the upper compression plate.
