摘要： X-ray systems for use in high-resolution imaging applications with an improved power rating are provided. An X-ray source comprises at least one integrated actuator unit (206, 206′, 206a or 206b) for performing at least one translational and/or rotational displacement by moving the position of the X-ray source's anode (204, 204′, 204a′ or 204b′) relative to a stationary reference position. This helps to overcome power limitations due to an overheating of the anode at its focal ̂spot position (205). In addition to that, a focusing unit (203) for allowing an adapted focusing of the anode's focal spot (205) which compensates deviations in the focal spot size resulting from said anode displacements and/or a deflection means (211, 21 Ia or 21 Ib) for generating an electric and/or magnetic field deflecting the electron beam (202, 202a or 202b) in a direction opposite to the direction of the rotary anode's displacement movement may be provided.

摘要： 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.

摘要： When performing nuclear (e.g., SPECT or PET) and CT scans on a patient, an imaging system (10) includes three or more carbon nanotube x-ray sources (20) are circumferentially spaced along an arc of a rotatable gantry (16) that spans a distance larger than a maximum cross-sectional dimension of a section of a patient (14) to be imaged. The x-ray sources are sequentially pulsed to emit x-rays for scanning a section of a patient (14) including a volume of interest (VOI) (13). Only one source (20) is in an ON state at a time to create a duty cycle, which reduces cooling time for the respective sources as well as radiation dose to the subject. X-rays traversing the patient (14) are received at a flat panel x-ray detector (22) that has a width smaller than the maximum cross-sectional dimesion, which further reduces the weight and size of the system (10).

摘要： It is described a low ohmic Through Wafer Interconnection (TWI) for electronic chips formed on a semiconductor substrate (600). The TWI comprises a first connection extending between a front surface and a back surface of the substrate (600). The first connection (610) comprises a through hole filled with a low ohmic material having a specific resistivity lower than poly silicon. The TWI further comprises a second connection (615) also extending between the front surface and the back surface. The second connection (615) is spatially separated from the first connection (610) by at least a portion of the semiconductor substrate (600). The front surface is provided with a integrated circuit arrangement (620) wherein the first connection (610) is electrically coupled to at least one node of the integrated circuit arrangement (620) without penetrating the integrated circuit arrangement (620). During processing the TWI the through hole may be filled first with a non-metallic material, e.g. poly silicon. After forming integrated components (620) on top of the front surface the substrate (600) may be thinned and the non-metallic material may be substituted with the low ohmic material, which is in particular a metallic material.

摘要： The invention relates to an X-ray detector for detecting X-radiation, as used, in particular, in computer tomographic (CT) systems. The X-ray detector in accordance with the invention is composed of a photo sensor device, which comprises individual detector elements (1), above which scintillator elements (2) are disposed. These convert the incident X-ray light (6) into visible or UV light (7), which is detected by a photodiode (4) located on the detector element (1). In accordance with the invention, a micro-lens (3), which focuses the light (7) departing from the scintillator element (2) onto the photodiode (4), is disposed between the scintillator element (2) and the detector element (1). It is possible, in this manner, to use large areas of the detector element (1) for further electronic components (5) outside the photodiode (4), and, at the same time, to ensure a high DQE (Detection Quantum Efficiency) in that the light (7) departing from the scintillator element (2) is virtually fully exploited. The crosstalk from scatter radiation from adjacent detector elements is effectively prevented simultaneously.
