X-ray device for tomosynthesis
An X-ray device for the formation of slice images of an object to be examined including an X-ray source, an X-ray detector, a transport device for moving the object during the acquisition of a series of X-ray projection images of the object in a movement plane situated parallel to the imaging plane, and a control device for controlling the acquisition of the X-ray projection images and the transport device. Slice images of the object are formed from the X-ray projection images by a tomosynthesis method. In order to enable the formation of slice images of large objects to be examined, or of large parts thereof, within a period of time which is as short as possible, the X-ray source and the X-ray detector are stationary during the acquisition of the X-ray projection images and the control device is configured such that the speed of motion of the object and the moments of acquisition of the X-ray projection images are such that all points to be examined in an examination zone of the object are imaged in at least 10, but preferably in at least 50 different X-ray projection images.
