摘要： 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.

摘要： To scan an object with differently shaped cone beams (112, 122), the present invention provides a CT scanner with a moveable X-ray tube (the meaning of "move the x-ray tube among a plurality of predefined positions" also covers the situation that the anode disk is moved among a plurality of corresponding positions, while the shell of the x-ray tube does not move). The X-ray tube is not only moveable along the axial direction, but also along the radial direction of the CT scanner gantry. The scanner comprises an X-ray tube, which X-ray tube further comprises: an anode disk (100), comprising a plurality of focal tracks (110, 120) each focal track being cone-shaped with an anode angle (114, 124) different from the anode angle(s) of the other focal track(s); and a first cathode (210), configured to emanate an electron beam targeting at least one of the plurality of focal tracks. When different focal tracks are bombarded by electron beams, different X-ray beams (112, 122) with differently shaped cone beams are generated.

摘要： Two proposals are made for power supply systems comprising at least one resonant inverter and one control unit. According to the first proposal the power supply system comprises two inverters and produces two output voltages, the control circuit processing as an actual value on the one hand the sum of and on the other hand the difference between the two output voltages. According to the second proposal a control circuit does not directly process the controlled variables for a power supply system comprising at least one inverter, but difference units for controlled variables determine the deviations from a preceding sampling instant and these difference values are processed. Also the correcting variable calculated in this way is a difference value which is converted into a correcting variable value by a correcting variable summing unit. The two proposals can be advantageously combined. As an important improvement is proposed the use of a limiting controller which generally becomes active in case of imminent transgression of a maximum value and which limits the actuation. The control circuit is preferably used as a digital control circuit for a state space control.
摘要翻译：对于包括至少一个谐振逆变器和一个控制单元的电力供应系统提出了两个建议。根据第一个提议，电源系统包括两个反相器并产生两个输出电压，一方面将控制电路作为实际值进行处理，另一方面是两个输出电压之间的差值。根据第二方案，控制电路不直接处理包括至少一个逆变器的电源系统的受控变量，但是用于受控变量的差分单元确定与先前采样时刻的偏差，并且处理这些差值。此外，以这种方式计算的校正变量是通过校正变量求和单元被转换为校正变量值的差值。这两个方案可以有利地组合。作为重要的改进，提出了一种限制控制器的使用，该限制控制器通常在即将发生最大值并且限制致动的情况下变得有效。控制电路优选地用作用于状态空间控制的数字控制电路。

摘要： The invention relates to a system (31) for generating spectral computed tomography projection data. A spectral projection data generation device (6) comprising an energy-resolving detector generates spectral computed tomography projection databased on polychromatic radiation (4), which has been provided by a radiation device (2), after having traversed an examination zone (5), and a reference values generation device generates energy-dependent reference values based on radiation, which has not traversed the examination zone. A spectral parameter providing unit (12) provides a spectral parameter being indicative of a spectral property of the radiation device based on the energy-dependent reference values. In particular, spectral properties of the radiation device can be monitored over time, wherein this information can be used for, for instance, correcting the spectral computed tomography projection data, and/or, if undesired spectral properties of the radiation device are indicated, triggering a replacement of the radiation device.
