摘要： A compact X-ray source is disclosed, improving controllability an insulation from unwanted high voltage effects. In one aspect, an active variable conductance device (130, 330) connected in series with the cathode is used in a closed loop, feedback arrangement to control the cathode beam current; the current flowing through the device to the cathode being directly sensed and compared with a desired current level. The result of the comparison is used to control the conductance of the device, thereby directly influencing the cathode current. A second aspect provides an extension of a Faraday cage, whereby the secondary winding of a transformer used to supply power to components within the cage is shielded within a coaxial, tubular member connected to the cage and extending outwardly from it.

摘要： The invention relates to a power supply unit with an inverter which co-operates with a resonant circuit (L, C) and can be controlled so as to adjust the output power by means of a control unit (6). The power supply unit is characterized notably by the fact that it is formed by a first and a second switching unit (S1, S4; S2, S3) whereby a voltage of a first polarity can be applied to the resonant circuit (L, C) in a first switching state and a voltage of a second polarity can be applied thereto in a second switching state, the switching states being switchable by the control unit (6) in such a manner that in a first mode of operation for low output powers the output power can be adjusted by changing the duration of the switching states at an essentially constant switching frequency fs which is at least a predetermined factor lower than the resonance frequency fres of the resonant circuit, and that in a second mode of operation for high output powers the output power can be adjusted by changing the switching frequency in the range of the resonance frequency.

摘要： A scanning beam digital x-ray imaging system according to the present invention includes an x-ray tube (10) having an electron beam source (161) and a target anode (50). Circuitry is provided for focussing the beam (164) and scanning the beam (20, 30) across the target anode (50) in a predetermined pattern such as a serpentine scan pattern. A collimating element (90), preferably in the form of a perforated grid containing an array of apertures (140), is interposed between the x-ray source (50) and an object to be x-rayed (80). The apertures (140) are oriented to form x-ray beams (100) converging at a detector array (110) on a plane (270) located a selected distance from the collimating element (90). That distance is selected to allow placing the object to be x-rayed (80) in between the collimating element (90) and the detector array (110). A segmented x-ray detector array (110) containing a rectangular matrix of detector elements (170) is located in the detection plane (270). A focal plane (280) is created which gives optimal resolution at a particular, selectable distance from the x-ray source (50).

摘要： An x-ray source can include an x-ray tube and a power supply. The x-ray tube can be removably affixed to the power supply in a rigid manner with the x-ray tube movable and holdable along with the power supply when affixed thereto. A releasable coupling between the x-ray tube and the power supply can create an interface defining a potential arc path. A means, such as a non-linear plug and socket junction, a gasket, or an electrically conductive sleeve, can be used for resisting arcing along the potential arc path.
