ABSTRACT:
The invention relates to a mammography unit, comprising a C-arm which is mounted on a turning axle (2) adapted to be vertically (arrow C) movable on an upright column (1) and which is pivotable about the turning axle (2) (arrow D), one leg (3) of said C-arm being provided with an X-ray tube (4) and the opposite leg (5) with an image receptor, and said unit further comprising a compression element (6) for compressing the breast to be imaged against the image receptor. The C-arm is further adapted to move linearly (arrow A) in substantially radial directions in the direction transverse to the turning axle (2). The unit comprises elements (20, 21) for controlling the linear motorized movement of the C-arm (arrow A) and the relative compressive movement of the compression element (6) (arrow B) to occur simultaneously at a substantially equal speed for compressing the breast between the compression element and the image receptor.
