The present invention relates to a kind of device (10), for visualization of 3 d object, x-ray imaging system (1) visualized objects, for visualization of 3 d object, and computer program element, there is this computer program element of storage for controlling this equipment (10) and computer-readable medium. The device (10) includes processing unit (11) for visualization of 3 d object. Processing unit (11) is configured to provide the projection plane 2D (23) of image. Processing unit (11) is configured to the object (24) that the initial three-dimension object of project (22) obtains anti-2D from the image of initial plane (27) and the transversal projection transformation perspective planes 2D (23). The transversal projection converts projective transformation, wherein each parallel lines for constituting contour of object tend to the other side 2D projection planes (23) of the point collected than initial. Processing unit (11) is configured to the reversed 2D objects (24) of a mirror and realizes mirror image mistake 2D objects (25). Processing unit (11) is configured to the three-dimension object (26) that project mirror image mistake 2D objects (25) return to initial plane (27) offer correction. The three-dimension object (26) that processing unit (11) is configured to projection correction arrives the image of 2D projection planes (23) again to provide last three-dimension object (28) and occur with non-anti-projection.
