摘要： In order to regulate the dose rate, the pulse-pause ratio of the inverter is changed. For this purpose, the regulator can be designed in such manner that, within a predetermined range of the error signal it changes this pulse-pause ratio via a regulating unit and, upon transgression of this range, changes the peak voltage supplied to the inverter via a regulator unit upon constant maintenance of a minimum pulse-pause ratio.

摘要： An x-ray examination installation includes an x-ray source for irradiating an examination subject with x-rays, and an automatic exposure unit having a radiation detector composed of a matrix of detector elements. Only the output signals of specified detector elements, which define the measuring field within which an optimum exposure should ensue, are utilized for generating a signal which is then supplied to the x-ray source for controlling the exposure dose. The automatic exposure unit is operated according to a method wherein a distribution of the grayscale values in a test image is first calculated, and subsequently the main image is produced with the previously-calculated distribution of grayscale values superimposed in the main image.

摘要： A pinhole camera forms an image of the optical focal spot of an x-ray tube on a radiation-electrical transducer comprising an intensifier foil and a matrix of photo-sensitive detectors. A processing circuit including an adjustable amplitude selector selects detector output signals for transmission to a video monitor. A calibrated measuring grid can be superimposed on the focal spot image on the monitor.

摘要： An automatic x-ray exposure unit for mammography permits a correction of the mAs product dependent on the subject thickness without the need for obtaining a transparency signal, and thus without the need for the double detector normally needed for that purpose. The automatic x-ray exposure unit permits the correction to be undertaken on site, prior to conducting an actual examination, and thus can be used for film/foil systems, such as customized systems for which no previous transparency data has been obtained. This is accomplished in an automatic x-ray exposure unit where the mAs product is obtained for a fraction (1/n) of the total exposure, and a total exposure value is then obtained by multiplying the fractional value by n. These values are used to generate a characteristic curve, which is stored, for the film/foil system being used. If it is then necessary to switch (adjust) the mAs value due to the subject thickness, this can be done using the stored curve.

摘要： An x-ray diagnostics installation for mammography exposures has a radiation detector for making a radiation measurement used to calculate the average parenchyma dose. The radiation detector is disposed on the support table next to the measurement field in which the mammary gland is disposed, and supplies a signal to a computer corresponding to the measured radiation dose at the detector location. The computer is programmed with the dependency of the average parenchyma dose, with respect to the radiation dose at the location of the radiation detector, and thus the computer generates a value corresponding to the average parenchyma dose, obtained by direct measurement rather than by calculation.

摘要： In an exemplary embodiment, two radiation detectors are present which are covered on their inlet sides for the radiation by two x-ray filters of different absorption. A divider divides the two output signals of the radiation detectors so that its output signal is a measure of the time variation of x-ray tube voltage during an exposure. The output signal of the divider is supplied to a time measurement circuit which provides a measure of the exposure time during which the x-ray tube voltage is greater than or equal to a predetermined value.

摘要： In an x-ray diagnostics installation for mammography, an automatic setting of the optimum beam quality ensues in combination with transparency matching. A set of exposure parameters corresponding to different thicknesses of the examination subject is stored in a memory (reference values). At the beginning of an x-ray exposure, a comparator compares the transparency signal (actual value) to the exposure parameters (reference value) interrogated from the memory dependent on the current thickness of the examination subject, and influences the x-ray tube voltage for the purpose of a rated/actual value comparison without interrupting the exposure.

摘要： An automatic x-ray exposure unit has first and second radiation detectors disposed sequentially and in registry in the direction of radiation propagation following the examination space. Each radiation detector is formed by a matrix of detector elements, also in registry. The detector elements are connected to a computer which calculates the quotient of the signals of each pair of detector elements in the first and second radiation detectors which are in registry. Those pairs of detector elements having a signal quotient which is above a predetermined threshold are automatically taken into consideration for selecting the measuring field for an x-ray exposure.
