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: A source (19) for multiple energy X-ray generation in particular by field emitting carbon nanotubes (1, 2) is presented. In order to achieve a spatial overlap of the trajectories of the X-ray beams coming from different emitters, a focusing unit (7, 9) is supplied to the emitted electrons (28, 29). A fast switching between the emission of the different carbon nanotubes allows multiple kilovolt imaging. Independent determination of multiple focal spot parameters by the focusing unit leads to the possibilities of fast switching between different spot geometries and spatial resolutions. This might be seen in FIG. 1.

Abstract: The invention relates to an X-ray source (100) with an electron-beam-generator (120) for generating electron beams (B, B′) that converge towards a target (110). Thus the spatial distribution of X-ray focal spots (T, T′) on the target (110) can be made denser than the distribution of electron sources (121), wherein the latter is usually dictated by hardware limitations. The electron-beam-generator (120) may particularly comprise a curved emitter device (140) with a matrix of CNT based electron emitters (141) and an associated electrode device (130).

Abstract: An electron emitter (1) and an X-ray tube (100) comprising such electron emitter (1) are presented. The electron emitter (1) comprises a cathode (3) and an anode (5) wherein the cathode (3) comprises an electron emission pattern (9) of a plurality of local areas (11) spaced apart from each other, each area being adapted for locally emitting electrons via field emission upon application of an electrical field between the cathode (3) and the anode (5). Electron beams (15) emitted from the local areas (11) may generate several X-ray source intensity maxima in a specific geometric pattern. An apparent loss in spatial resolution due to overlapping images on a detector can be corrected by using specific intensity patterns for the X-ray source (100) and by applying dedicated decoding algorithms on the acquired image such as coded source imaging (CSI).
