    Abstract: An X-ray emitter includes an emitter housing in which an X-ray tube is disposed and held in the emitter housing by a fixing facility. The fixing facility includes a fixed bearing disposed on the cathode side and a floating bearing disposed on the anode side. At least the floating bearing has at least one damping element. In the X-ray emitter, the X-ray tube is aligned inside the emitter housing and fixed in a respectively low-vibration or vibration-damped manner, resulting in a more stable focus position relative to a beam exit and also a correspondingly improved image quality.

    Abstract: The embodiments relate to a rotary anode arrangement with a rotary anode, a rotor for driving the rotary anode and a stator, which exerts a torque on the rotor. The stator includes at least one coil for generating a first magnetic field and at least one permanent magnet for generating a second magnetic field. The embodiments also relate to an X-ray tube with the rotary anode arrangement. The embodiments offer the advantage that a high electromagnetic utilization is possible with a synchronous motor that is excited by permanent magnets.

    Abstract: The embodiments relate to a CT system with a stationary part and a rotatable part, which is supported rotatably in the stationary part. At least one x-ray tube unit cooled by a cooling fluid, an x-ray detector lying opposite the x-ray tube unit, and a cooling device coupled in terms of fluid technology to the x-ray tube unit via a coolant circuit are disposed in the rotatable part. A cooling air channel, through which cooling air is able to be fed into the rotatable part, and an exhaust air channel, through which heated exhaust air is able to be taken away from the rotatable part, are disposed in the stationary part. In accordance with the embodiments, at least one overpressure relief valve is disposed in the coolant circuit, through which the cooling fluid is able to be conveyed away in the exhaust air channel.

    Abstract: The present invention relates to a radiographic imaging apparatus and a corresponding radiographic imaging method. The proposed apparatus comprises an X-ray source and a photon counting X-ray detector. The X-ray source comprises a rotary X-ray anode having a number of radial slits and a target layer provided on a surface of said rotary X-ray anode in between said radial slits for emitting X-ray radiation when hit by said electron beam. The said photon counting X-ray detector comprises a persistent current sensing and correction unit for sensing a persistent output current in a blanking interval during which no X-ray radiation is emitted by said X-ray source and for using the sensed persistent output current to correct a detector signal in a subsequent measurement interval during which X-ray radiation is emitted by said X-ray source.

    Abstract: X-ray sources and production of X-rays, in particular, producing monochromatic x-rays is provided. More specifically, a method for producing X-rays and the use of the X-ray source for x-raying bodies (for example human bodies). An aerogel, for example in the form of a rod, may be provided in a housing as a target. Said target may be bombarded with an electron beam, the aerogel being vaporized due to the extreme low density and the high energy. As a result, the target is guided by means of a roller such that an unused target for producing, in particular, the monochromatic X-rays, is always available.
