    摘要: The device makes it possible to expose a patient to an approximate flux of X-ray beams without the interference of light and X-rays from outside in the X-rays from an X-ray's generation source (X-ray tube) during irradiation of the X-rays upon the patient and to detect the dose of X-rays in the form of an electrical signal. In such a process, it uses the signal as a detection medium to a normal dose of X-rays so as to permit the irradiation of an exact and normal amount of X-rays upon the affected part.

    摘要: An X-ray imaging diagnostic apparatus emitting a low X-ray radiation dose is disclosed as comprising an X-ray generating source for exposing an object, an optical system having a fluorescent screen for receiving the X-ray image at an aperture portion thereof, a high sensitivity imaging device coupled directly to the optical system and receiving an X-ray image from the fluorescent screen for radiographing the X-ray image, a control unit for amplifying the output from the high sensitivity imaging device and for controlling the exposure time of X-ray radiation emitted from the X-ray generating source, an image storing memory circuit connected to the control unit for storing an image signal therefrom and a monitor circuit for displaying the image signal. The exposure time of the X-ray generating source is controlled to be at most less than 1/100 second by the control unit and the image of an object obtained on the fluorescent screen is imaged with a high resolution and a high sensitivity so that the resultant image can be recorded and monitored. The exposure time of the X-ray radiation is decreased as low as possible by using the high sensitivity imaging device, so that an X-ray radiation dose applied to a human body is lowered as compared to conventional X-ray diagnostic apparatus.

    摘要: A method and apparatus for X-ray examining organs and parts of the body of human beings and/or animals, wherein the X-ray image is reproduced by means of a television circuit on the viewing screen of a monitor. Photographs of the X-ray image are taken as a film disposed in front of the screen of the monitor is exposed to the monitor picture for a period of time including a plurality of image scan cycles. During this period of time the gain in the television circuit is varied in accordance with a time function such that the brightness of the monitor picture remains constant during this period.

    摘要: A circuit arrangement for the transmission of picture details through a video chain emphasizes blurred contours and is connected in series with a section serving for the transmission of video signals separated from the synchronized signals of the video chain. The circuit arrangement contains delay means having a tapping point, an adder, and a frequency-independent level control unit that connects the input of the delay means to the first input of the adder. The frequency-independent level control unit is connected between the tapping point and the second input of the adder, and the output of the delay means is connected to the third input of the adder. The first and third inputs of the adder belong to an operation having a common sign opposite to that of the second input, and its input is formed by the input point of the delay means. The output is formed by the output of the adder.
