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: 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: The invention relates to a device for generating X-rays (69) comprising a source (5) for emitting electrons and a carrier (7) which is provided with a material (9) which generates X-rays as a result of the incidence of electrons. The device comprises a dynamic groove bearing (17) having an internal bearing member (23) and an external bearing member (21) by means of which the carrier is journalled so as to be rotatable about an axis of rotation (15). A first one (21) of the bearing members is connected to the carrier. A bearing gap (57, 59, 61) containing a liquid lubricant is present between the bearing members. The bearing gap forms part of a heat transfer path via which the heat, which is generated during operation as a result of the electrons impinging upon the X-ray generating material, is conducted from the carrier to the surroundings of the device. To improve the rate of heat transfer via said heat transfer path, the carrier (7) and at least a portion (33, 37) of said first bearing member (21), which portion at least partially covers the bearing gap (57, 59, 61), constitute an integral part of the device. Preferably, the carrier and said portion of the first bearing member are manufactured from a single piece of material. In this manner the heat transfer path does not include any material separations between the carrier and the part of the bearing gap covered by said portion of the first bearing member.
