摘要： An x-ray diagnostics installation has an x-ray image intensifier video chain which includes a semiconductor detector composed of pixels arranged in a matrix, serving as the video pick-up and a detector for identifying the average image brightness at the output luminescence screen of the x-ray image intensifier within a predetermined image region. A first read-out circuit is provided for pixels of a first group in the image, which is operated with a read-out clock at a first frequency, and a second read-out circuit is provided for pixels of a second group distributed over the area of the semiconductor detector, which is operated with a read-out clock at a second frequency. The second frequency is higher than the first frequency. The output signals of the pixels of the second group are supplied to an evaluation circuit, and the output signals of the first group of pixels are supplied to the video chain. Image production parameters, such as image brightness, can be controlled on the basis of the output signals of the second group of pixels.

摘要： A telerecording system for producing x-ray images, having an x-ray image intensifier video chain which includes a semiconductor image converter, has a detector which recognizes blooming in the semiconductor image converter and which given blooming, causes at least two x-ray images of different brightness to be acquired by the semiconductor image converter. One of the images is exposed attenuated in comparison to the other so that no blooming ensues. Image signals from the two x-ray images are then superimposed in a mixer unit and the resulting image is displayed.

摘要： In television transmission of medical X-ray photographs and in television X-ray fluoroscopy (e.g. during surgery), where a great brightness contrast range is presented, the illustrated system obtains a blurred video signal representative of the brightness of relatively large regions of the visible light image and adjustably selects high amplitude parts of such signal to synchronously modulate the scanning electron beam of a storage type television camera tube. In this way darker image areas are transmitted with full contrast for reproduction of fine image details as particularly required in medical X-ray technology, while excessively bright areas are attenuated to a desired degree.

摘要： A radiological system, wherein x-ray images (radiation images) are produced and are converted, through a video chain, for display as a video image, the system having a modulation transfer function, has the capability of influencing the modulation transfer function dependent on ambient light which is present at the display. To that end, a control unit is provided which provides two-dimensional control of the modulation transfer function dependent on illumination which is present in the environment of the display. The control is effected by means of a two-dimensional spatial frequency filter.

摘要： In a radiological installation comprising an image pick-up system having a memory for individual images and having an image playback unit, an overall image formed of at least two individual images is capable of being portrayed, the number of lines thereof being at least largely independent of the sum of the number of lines of the individual images. For that purpose, the overall image is compiled line-by-line with a processor controller such that respectively one row of stored picture elements of an individual image forms a section of one line of the overall image, and a corresponding row of stored picture elements of at least one further individual image respectively adjoins this section.

摘要： An X-ray diagnostics installation with spatial frequency high-pass filtering has an X-ray tube, in image intensifier video chain, first and second image memories, and a difference stage for subtracting images in the memories and thereby forming a difference signal between first video signals and chronologically succeeding second video signals. The resulting image is displayed on a monitor. The installation further has a control unit for controlling the size of the tube focus. A video signal for an X-ray exposure produced using a first size of the tube focus is entered into one of the memories, and this signal is subtracted in the difference stage from a video signal for an X-ray exposure produced with a second size of the tube focus.
