Abstract: A microminiature X-ray tube with a triode structure using a nano emitter is provided, which can increase a field emission region as much as possible by means of nano emitters fine-patterned in a cathode to not only increase an emission current per unit area as much as possible but secure high electrical characteristics, reliability, and structural stability by means of a cover and a bonding material. In addition, gate holes having a macro structure can be formed in the gate to promote electron beam focusing by means of the gate without using a separate focusing electrode and to prevent a leakage current from occurring on the gate. Further, an auxiliary electrode can be formed on a top or an inner surface of a cover applied for structural stability to further promote the electron beam focusing and to control the output amounts per individual X-ray tubes output according to current switching to be equal to each other.

The x-ray source has a plurality of x-ray emitters arranged alongside one another. Each x-ray emitter is assigned to a part area of the x-ray detector. The x-ray beam generated by the x-ray emitter is collimated onto the assigned part area. A first x-ray emitter is activated for emitting a first x-ray beam onto a first part area and image data of the first part area is read out. Subsequently a further x-ray emitter for emitting a further x-ray beam onto a further part area of is activated and image data of the further part area is read out. The steps are repeated until image data for all part areas of the x-ray detector is read out. The read out image data is combined into an x-ray image.

Abstract: A compact apparatus can form multi X-ray beams with good controllability. Electron beams (e) emitted from electron emission elements (15) of a multi electron beam generating unit (12) receive the lens effect of a lens electrode (19). The resultant electron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generated by the transmission-type target portion (13) pass through an X-ray shielding plate (23) and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-ray extraction windows (27) of a wall portion (25) into the atmosphere.

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.
