摘要： The present invention relates to hydrodynamic bearings, X-ray tubes, X-ray systems, and a method of manufacturing a hydrodynamic bearing for an X-ray tube. The rotor of a hydrodynamic bearing is supported, in steady-state operation, by the pressure of lubricant which is pumped through grooves in the rotor. When the rotor is speeding up or slowing down, the pumping force will not be sufficient to lift the rotor clear of a stationary bushing, and damage, caused by direct contact of the metal surfaces of the bearing, can occur. Providing special coatings on the bearing surfaces can ameliorate this effect.

摘要： An imaging detector module (112) of an imaging system includes at least one detector pixel (114) and self-diagnosing circuitry (116). The self-diagnosing circuitry includes a microprocessor (202) and at least measurement device (210). The micro processor controls the at least measurement device to measure at least one parameter of the at least one detector pixel, wherein a value of the at least one parameter is indicative of a health state of the imaging system. A method includes employing self-diagnosing circuitry embedded in an imaging detector module to measure at least one parameter of at least one detector pixel of the imaging detector module. A value of the at least one parameter is indicative of a health state of the imaging detector. The method further includes generating, with the self diagnosing circuitry, a signal indicating a health state of the imaging detector module based on the measured at least one parameter.

摘要： The present invention relates to a grating in X-ray imaging. In order to provide a grating with a facilitated stabilization, a grating (10) for X-ray imaging is provided that comprises a grating structure (12) with a first plurality of bar members (14) and a second plurality of gaps (16). A fixation structure (18) is arranged between the bar members to stabilize the grating bar members. The bar members are extending in a length direction (20) and in a height direction (22). The bar members are also spaced from each other by one of the gaps in a direction transverse to the height direction. The gaps are arranged in a gap direction parallel to the length direction. The fixation structure comprises a plurality of bridging web members (24) that are provided between adjacent bar members. Further, the web members are longitudinal web members that are extending in the gap direction and that are provided in an inclined manner in relation to the height direction. The inclination is provided in the gap direction.

摘要： An interventional X-ray system is proposed, the system including a multi X-ray source unit positioned below a patient table. This ‘multiblock’ may comprise several x-ray sources with focal spot positions distributed along the x-y (table) plane. The x-ray sources are operable in a switching scheme in which certain x-ray sources may be activated in parallel and also sequential switching between such groups is intended. The switching may be carried out so that several images with different projection angles can be acquired in parallel. In other words, an optimal multi-beam X-ray exposure is suggested, wherein fast switching in one dimension and simultaneous exposure in the 2nd dimension is applied.
