    Abstract: An X-ray generating apparatus for generating X-rays by irradiating a target with an electron beam. Wherein the apparatus includes a vibration applying means for vibrating the target in directions parallel to a surface thereof. A colliding spot of the electron beam is movable on the target while maintaining an X-ray focus in the same position on the electron beam without fluctuating the X-ray focal position. This enlarges an actual area of electron collision on the target to disperse the generated heat, thereby to suppress a local temperature rise of the target due to the electron collision. The X-ray generating apparatus is compact, and has a long life and a high X-ray intensity.

    Abstract: A distributed X-ray source (3) and an imaging system (1) comprising such an X-ray source (3) are proposed. The X-ray source (3) comprises an electron beam source arrangement (19) and an anode arrangement (17). The electron beam source arrangement (19) is adapted to emit electron beams (24) towards at least two locally distinct focal spots (27) on the anode arrangement (17). Therein, the X-ray source is adapted for displacing the anode arrangement (17) with respect to the electron beam source arrangement (19). While the provision of a plurality of focal spots allows acquisition of projection images under different projection angles thereby allowing reconstruction of three-dimensional X-ray images e.g. in tomosynthesis application, a displacement motion of the anode arrangement (17) with respect to the electron beam source arrangement (19) may allow for distributed heat flux to the anode arrangement thereby possibly reducing cooling requirements.

    Abstract:  ターゲットに電子ビームを照射してX線を発生させるX線発生装置であって、前記装置は、前記ターゲットの面方向に前記ターゲットを振動させる振動付与部を備える。本発明により、X線焦点位置を変動させることなく、電子ビーム上のX線焦点位置を同じ位置に保ちつつ、電子ビームの衝突点をターゲット上で移動でき、ターゲットにおける実効的な電子衝突面積を大きくできるので、発生する熱を分散させて電子衝突による集中的なターゲットの温度上昇を抑制できる。したがって、長寿命で稼働率が高いコンパクトなX線発生装置を提供することができる。
