Abstract: A method for reconstruction of an actual three-dimensional image dataset of an object during a monitoring process is proposed. Two-dimensional X-ray projection images which correspond to a recording geometry are continuously recorded from different projection angles. The three-dimensional image dataset are reconstructed from a first number of these projection images, especially by a back projection method. The proportion of the oldest projection image contained in the current three-dimensional image dataset is removed from the three-dimensional image dataset and the proportion of the actual projection image is inserted in the three-dimensional image dataset after each recording of the actual projection image.

Abstract: A rotatable anode for an X-ray tube comprises a first unit (901) for being hit by a first electron beam, and at least a second unit (902) being hit by at least a second electron beam, the second unit being electrically isolated from the first. In addition, an X-ray system comprises the anode, a main cathode for generating an electron beam, and first electrical potential, and an auxiliary cathode for influencing a second electrical potential. The main cathode deflects the electron beam to heat the auxiliary cathode. Furthermore, a device determines electrical potential by detecting a point of impact of the electron beam onto the anode and/or by detecting an X-ray spectrum of radiation starting from the anode. The electron beam hits the first unit and is deflected, wherein the deflected beam hits the second unit the point of impact. The first unit and/or second unit emit radiation.
