    • For boosting/blanking the filament current of a cathode of an X-ray tube the temporal variation of the tube current of the X-ray tube is measured and stored in a first memory. Then an iterative boosting/blanking is performed wherein the boosting/blanking current is applied to the filament for a short time interval (Δt), based on the stored temporal variation of the tube current the tube current after the short time interval (ΔT) is determined, and the tube current is stored in a second memory. Based on the stored temporal variation of the tube current it is determined if the tube current (IE) is less than a target value (IE2) thereof, and if so, the boosting/blanking current is applied to the filament for an additional time interval (Δt), else it is determined that the tube current (IE) is equal to the target value (IE2). Therefore, the tube current (IE) after each time interval (Δt) is known (may be determined from the tube current data stored in the second memory)such that the iterative boosting/blanking may be interrupted anytime.

    • A method for controlling X-ray diagnostic apparatus with medium frequency conversion in the main circuit involves attaining the voltage operating conditions without having to set the high voltage on the voltage leading edge after switch-on of the apparatus according to a signal indicating correspondence between the intensity of irradiation behind the object being examined and a predetermined reference value. In a preferred embodiment, this is achieved by using a set of reference values, including the basic reference value established on the basis of the maximum permissible load capacity of the X-ray tube, while the remaining reference values are each matched with one of the relevant diagnostic high voltage ranges, and the corresponding electrical quantity (mAs). In determining reference values, the radiographic focal distance and X-ray tube anode current are taken into account. The X-ray apparatus compsises an X-ray tube (1), a high-voltage generator consisting of mains rectifier (3), smoothing LC filter (4), medium-frequency inverter (5), high-voltage transformer (6) and high-voltage rectifier (7), and a heat unit (8).

    • The present invention relates to X-ray radiation with multiple photon energies. To provide an X-ray tube capable of generating multiple-energy X-ray radiation with an improved switching capacity and a reduced design setup, a multiple-energy X-ray tube, comprises a cathode (12), an anode (14), and a switchable current controlling unit (16). The cathode comprises a first connection port (18), which is connectable with a negative terminal of a generator to be supplied with a high-voltage energy to generate a voltage potential between the cathode and the anode. The anode is an electrically floating isolated anode. The switchable current controlling unit is electrically arranged between the anode and a second connection port, which second connection port is connectable with a ground or positive terminal of the generator to provide an adjustable current transfer (30) from the anode via the switchable current controlling unit and the second connection port to the generator. Further, the switchable current controlling unit is controllably adaptable such that at least a first current transfer and a second current transfer are adjustable, wherein the second current transfer is different from the first current transfer. The first current transfer leads to a first voltage between the cathode and the anode resulting in an electron beam (86) which generates X-radiation with a first spectrum, and the second current transfer leads to a second voltage between the cathode and the anode resulting in an electron beam (86) which generates X-radiation with a second spectrum, wherein the first X-ray spectrum is different from the second X-ray spectrum.
