摘要： A medical X-ray apparatus is provided with image detector elements 30 which are arranged in a matrix of rows and columns. In order to improve the noise behaviour of the read amplifiers 46 during the reading per row, a plurality of column conductors 36 is provided per column so that the read time is prolonged in proportion to the number of column conductors and the stray capacitance is reduced proportionally. Both steps reduce the noise in known manner. In the case of an integrated implementation, the conductors for driving the reading per row cannot be arranged arbitrarily close to one another because of their mutual capacitance, so that these conductors require a comparatively large surface area. In order to make a smaller surface area suffice for these conductors, according to the invention each read driver 42 is connected to at least two rows of image detector elements 30 which are not associated with the same column conductor, the number of rows thus connected to one read driver being at the most equal to the number of groups of image detector elements in one column.

摘要： The invention provides a method for compensating synchronization errors in non-impact printers, without influencing the transport of the record carrier and without changing the printing frequency of the printing elements. A control value is derived from a difference between the actual transport speed and a predetermined transport speed of the record carrier. This control value is used to vertically deflect the recording beam, after each picture line, by a fraction of the predetermined picture line spacing. The sum of the cumulative vertical deflections are compared with the value of the picture line spacing, and the recording of the next picture line is delayed by one deflection period of the recording beam when the sum is greater than or equal to the value of the picture line spacing.

摘要： A device for scanning an X-ray image where a previously locally uniformly charged photoconductor (1) is discharged in dependence on the local intensity, utilizing several electrometer probes which are arranged in a row and which line-wise scan the charge pattern of the photoconductor (1) which is successively displaced in the scanning direction, extending perpendicular to the line direction, the probes supplying, for each pixel, an image value which corresponds to a discharge at the relevant pixel. In order to eliminate streaky artefacts, the image values are applied to an analog-to-digital converter (5), the converted values being stored in an image memory (6), there being provided a signal processor (7) which subjects the image values of neighboring pixels in an image line to a low-pass filter function and which subjects the image values of pixels neighboring one another in the scanning direction to a high-pass filter function.

摘要： The invention relates to the elimination of streak-like artefacts in slit radiography which are caused by an axial excursion of the rotary anode X-ray tube used for making the radiographs. These streaks can be eliminated by adapting the speed of displacement of the X-ray beam, the number of revolutions per unit time of the anode and the intensity profile of the radiation beam to one another so that for each point the intensity modulation in the half-shade area, caused by the periodic displacement of the focal point, is compensated for.

摘要： The integrated capacitor structure comprises a first branch with a first capacitor (60) and a second branch with a second capacitor (70). The second capacitor (70) has a higher capacitance density and a lower breakdown voltage than the first capacitor (60). The first branch has a shorter RC time constant than the second branch, such that a voltage peak will substantially follow the first branch. This first capacitor (60) has a sufficient capacity to store the charge of the voltage peak. In one embodiment, the second capacitor (70) is a stacked capacitor. The structure is suitable for ESD-protection and may, to this end, additionally comprise diodes (21) and resistors (22).

摘要： A photodetector CCD pick-up device reads a storage phosphor record carrier via a light source on one side of the carrier with the photodetector device on the other side of the carrier. A drive displaces the carrier relative to the light source and to the CCD device. The light source illuminates the phosphor sub-surface of the record carrier to produce fluorescent light and which sub-surface comprises a plurality of pixels. The CCD pick-up device is arranged so that the charges in its cells produced by the fluorescent light displace in the same direction and at the same speed as the carrier.

摘要： An X-ray image amplifier tube designed with an input screen having a photocathode and with a detection screen which is opposite the latter and a short distance away for detection of a photo-electron beam which is generated by X-ray input image signals and is amplified in the tube. The detection screen is provided with a conversion coating for converting an image-carrying photo-electron beam into a potential excursion and to this end contains, for example, an amorphous selenium coating or a porous KCl coating. A variable potential can be applied both over the vacuum gap between the photocathode and the conversion coating and over the conversion coating itself and, as a result of this, high image brightness dynamics can be achieved without image disruption.
