摘要： An X-ray device and method of improving the quality of an image formed by an X-ray device are provided. The X-ray device comprises a source emitting a beam of X-rays toward an object to be examined. A detector for receiving the X-rays that pass through the object is connected to an image processor. An X-ray collimator comprising a translatable element and at least one aperture for narrowing the beam of X-rays is arranged between the X-ray source and the examined object. A method of improving the quality of an image formed by the X-ray device comprises the steps of narrowing the X-ray beam using the aperture of the collimator, moving the aperture through the X-ray beam to expose the object to be examined to the narrowed X-ray beam, and forming an image of the examined object based upon the highest intensity value received for each pixel of the detector.

摘要： Possible failure of x-ray tubes is predicted by monitoring and analysis of operating parameters considered leading indicators of failure. Historical data for a tube population is analyzed by discriminant analysis to develop a failure prediction algorithm. The algorithm is used to correlate operating parameters, or values derived from the operating parameters with a potential for tube failure. The operating parameters may include anode overcurrent events and spits, or spit rate exceeded errors for a diagnostic system in which the x-ray tube is installed.

摘要： An x-ray imaging apparatus receives an image-carrying x-ray beam on a flat amorphous silicon imaging panel with a light detector unit disposed behind. The imaging panel is of a multi-layered structure having sequentially a light-blocking layer which is opaque to visible light but transmissive to x-rays, a converting layer of a phosphorescent material for converting x-rays incident thereon into visible light, and a two-dimensional array of photosensitive elements of an amorphous semiconductor material such as amorphous silicon, adapted to undergo a detectable change in electrical characteristic in response to impingement of light. The light detector unit may be a simple light detector for receiving the light emitted from the converting layer and passed through regions between neighboring pairs of the array of photosensitive elements. Since the energy of light thus detected is directly proportional to the total light energy emitted from the converting layer, the output signal from such a light detector unit can be conveniently used for the exposure control of the imaging panel.

摘要： A process and measuring device for determining the tissue-equivalent dose in radiotherapy. First, the radiation dose is measured according to the process at a site by at least two sensors i and j. The sensors are designed such that the associated measuring signals S.sub.i and S.sub.j display different energy dependency of the detection sensitivity to ionizing radiation, a dose-independent quotient Q.sub.ij =S.sub.i /S.sub.j being formed from this difference. The tissue-equivalent dose D is then calculated from this dose-independent value. The advantages of this process are that the sensor material does not have to be adapted to the tissue and can therefore be freely selected, and the tissue-equivalent dose is determined highly accurately. The measuring device comprises three parallel fiber-optic sensors disposed equidistant in a plane, the outer sensors being identical and differing from the central sensor by differing energy dependency of the detection sensitivity to ionizing radiation.

摘要： A fuzzy control system, particularly for dose rate control in an X-ray diagnostics apparatus, such a control system converting input signals into output signals. A first and a second individual module are provided, whereby respectively at least two input signals can be supplied to the first and to the second individual module for generating an output signal. Compared to a fuzzy control system that does not comprise these individual modules, the rule base becomes smaller, only input conditions that have influence on the individual module need be provided with rules, so that a simple check of the rules for completeness is assured.

摘要： In an X-ray tube with a hydrodynamic slide bearing, an electron beam is caused to strike the focal point track area F on its rotary anode, which then emits X rays. An X-ray emission control device that sets the conditions for emitting the X rays stores as data the rises and drops in the temperature at the electron beam incident point and the other part on the focal point track surface of the anode. On the basis of the data, the input permission or inhibition conditions for the X-ray tube at every moment are calculated and the resulting conditions are displayed on a display unit. As a result, it is possible to perform a computing process in advance to determine whether or not X rays can be emitted under specific conditions without a permitting the rotary anode in the X-ray tube with a hydrodynamic slide bearing to melt and then display the results, thereby enabling a safe, efficient photographing control.
