摘要： For boosting/blanking the filament current of a cathode of an X-ray tube the temporal variation of the tube current of the X-ray tube is measured and stored in a first memory. Then an iterative boosting/blanking is performed wherein the boosting/blanking current is applied to the filament for a short time interval (Δt), based on the stored temporal variation of the tube current the tube current after the short time interval (ΔT) is determined, and the tube current is stored in a second memory. Based on the stored temporal variation of the tube current it is determined if the tube current (IE) is less than a target value (IE2) thereof, and if so, the boosting/blanking current is applied to the filament for an additional time interval (Δt), else it is determined that the tube current (IE) is equal to the target value (IE2). Therefore, the tube current (IE) after each time interval (Δt) is known (may be determined from the tube current data stored in the second memory)such that the iterative boosting/blanking may be interrupted anytime.

摘要： Es wird ein Verfahren und eine Vorrichtung zur Begrenzung einer in ein Objekt eintretenden Strahlung (Eintritts-Dosisleistung) bei der Bestrahlung des Objektes mittels einer Strahlenquelle (1), insbesondere bei der Belichtung von Röntgenaufnahmen, beschrieben. Dabei werden diejenigen Wertepaare einer Regelkurve, die zu einer Eintritts-Dosisleistung an dem Untersuchungsobjekt führen, die eine vorgegebene maximale Eintritts-Dosisleistung übersteigt, mit einem berechneten Faktor korrigiert. Dadurch entsteht eine korrigierte Regelkurve, die in voller Länge zur Einstellung gewünschter Röhrenparameter (Röhrenspannung, Röhrenstrom oder Ladung) genutzt werden kann, ohne dass die Gefahr eines Überschreitens der maximalen Eintritts-Dosisleistung besteht.

摘要： A thermal generator assembly for optimizing quantities of heat dissipated from an X-ray tube (20) and a high-voltage generator (10) that supplies power to the X-ray tube (20), an X-ray imaging system, and an X-ray apparatus overheat preventing method. Temperatures of the X-ray tube (20) and high-voltage generator (10) to be attained during scanning are estimated (60). If the temperatures exceed permissible temperatures, an indication that scanning is disabled is displayed (68). If optimization is designated, a control parameter such as a tube current or a tube voltage is optimized using binary search so that the temperatures will fall below the permissible temperatures. The X-ray tube (20) or high-voltage generator (10) will not overheat but operate with a temperature retained at the permissible temperatures or lower. Deterioration of the X-ray tube (20) or high-voltage generator (10) can be prevented. Eventually, highly reliably scanning can be ensured.

摘要： A maximum tube voltage value setting module 240a, a warming-up module 240b, a limit tube voltage control module 240c, a limit tube current control module 240d and a focus grid electrode control module 240e of an operation program 240 which respectively correspond to different maximum tube voltage values are stored in storage sections 32a-e of an X-ray tube control apparatus 3. When the maximum tube voltage value of an X-ray tube 1 is changed, an extraction section 34 extracts each module of the operation program 240 which corresponds to the maximum tube voltage value after being changed from the storage sections 32a-e. A communications section 36 sends the operation program 240 comprised of each extracted module to an X-ray tube controller 2 and overwrites it in a memory section 24.

摘要： An exposure management and control system and method for x-ray technique selection is provided. Optimal x-ray technique, which affects image quality, can be accurately predetermined to use for any application. A patient model is combined with a closed loop brightness control, using a parameter that does not affect image quality. This is used to create a control system that operates as a knowledge based control system. The x-ray system brightness control system comprises a first and second regulator. The first regulator is an image quality, or brightness, regulator. The brightness regulator can have multiple functions, such as peak mA control, power limiter, skin dose limiter, and an override function. The second regulator is a dose error regulator. The second regulator is independent of the first regulator, and cooperates with the first regulator to provide x-ray technique optimization independent of brightness control.

摘要： An improved x-ray image sensor system and method enables the use of an uncooled or only slightly cooled CCD array (18a) within a standard size x-ray film cassette (10). The sensor system enables the provision of a number of advanced functions such as remote diagnostic capability, variable image resolution, real-time exposure control, automatic x-ray detection, a low-power "sleep" mode, and automatic, closed loop optimization of image quality.

摘要： The invention relates to a computer tomography (CT) device, whose operational parameters (I, T) can be adjusted. Said device has a control unit and elements for pre-selecting a combination of operational parameters (I, T) for a medical examination which is to be performed. If a combination of operational parameters (I, T) has been preselected for a medical examination which is to be performed that may lead to an unacceptable operational state, a control unit determines a value for at least one operational parameter (I, T) which deviates from the pre-selected operational parameters (I, T). The scheduled examination can then be performed for this value whilst avoiding the unacceptable operational state, without any significant reduction in image quality, in relation to the pre-selected combination of operational parameters (I, T).
