摘要： An X-ray television apparatus applies an X-ray to an object to be inspected, converts the X-ray projection image of the object into an optical image by a fluorescent screen or an X-ray image intensifier, picks up the optical image by a TV camera, displays the video signal obtained by a TV monitor for fluoroscopic monitoring, and records radiograph of the object by using the video signal. Avalanche multiplication is caused on the photoconductive layer of the image pick-up tube of the TV camera so as to enable monitoring or imaging with high sensitivity at a low X-ray dose rate.

摘要： In a real-time digital radiographic apparatus, an image is picked up by means of a TV camera. In a fluoroscopic monitoring mode, an output of the TV camera is displayed on a display in real time. In a radiographic imaging mode, the output of the TV camera is A/D converted, subjected to a necessary image processing and held as image data for diagnosis. In the fluoroscopic monitoring mode, a beam scanning for an image pickup tube corresponding to an NTSC system is performed whereas in the radiographic imaging mode a high-density and low-speed beam scanning can be selected in which the number of scanning lines is increased and the frame rate is lowered. In order to suppressing the lowering of the maximum signal current derivable from the image pickup tube which may occur in such a high-resolution scanning, a target voltage of the image pickup tube in a high-resolution mode is changed to a value higher than a standard value of the target voltage, thereby acquiring an image which has a wide dynamic range and a high S/N ratio.
摘要翻译：在实时数字放射线照相设备中，通过电视摄像机拾取图像。在透视监视模式中，电视摄像机的输出实时显示在显示器上。在放射照相成像模式中，电视摄像机的输出被A / D转换，进行必要的图像处理，并作为用于诊断的图像数据保存。在透视监视模式中，执行对应于NTSC系统的图像拾取管的光束扫描，而在放射照相成像模式中，可以选择扫描线数量增加的高密度和低速光束扫描，帧速率降低。为了抑制在这样的高分辨率扫描中可能发生的从图像拾取管导出的最大信号电流的降低，将高分辨率模式的图像拾取管的目标电压改变为高于目标电压的标准值，从而获得具有宽动态范围和高S / N比的图像。

摘要： A real-time digital radiography system operates to introduce a X-ray image on a real-time basis and process the image for clinical diagnosis. The system provides for additional inputs, for example, clinical information material, which are also subject to digital image conversion. The system is designed to connect several TV cameras to an A/D converter which digitally converts the produced image to digital information, with one of the TV cameras for imaging the output image of an X-ray image intensifier, and the output of the one TV camera is selectively connected to the A/D converter. The output image of the X-ray image intensifier and other output images produced by separate TV cameras are connected to the A/D converter through a switching apparatus, and subsequently the digital output is processed.
