摘要： The display device is furnished with a channel plate (39) comprising channels (30, 30', 30") containing an ionizable gas (33), and the walls of the channels (30, 30', 30") being provided with electrodes (31, 32) for selectively generating a plasma discharge of the ionizable gas (33) during operation. The display device further comprises an electro-optical layer (35) of a material having an optical property which is governed by the discharge state of the plasma discharge. The display device is characterized in that at least one of the electrodes (31, 32) is furnished with a layer (37) comprising particles of a sputter-resistant material having an average diameter .ltoreq.2.5 .mu.m, preferably .ltoreq.1.5 .mu.m. The particles are preferably composed of rare-earth borides (for example LaB.sub.6) or ruthenium oxide.

摘要： An X-ray examination includes a filter for limiting the dynamic range of an X-ray image formed on an X-ray detector by irradiation of an object, for example a patient to be examined, by means of X-rays. The filter has a number of electrodes and grains or powder particles containing an X-ray absorbing material and suspended in a suspension liquid. When a voltage is applied to electrodes, X-ray absorbing material in the suspension will move to the excited electrodes under the influence of electrophoresis. A distribution with a desired X-ray absorption profile is adjusted by application of a suitable voltage pattern. The electrodes may have dimensions of, for example 0.5.times.0.5 mm, enabling an X-ray absorption profile to be obtained with a high spatial resolution. The X-ray absorption profile can be changed within a brief period of time, for example within one second, by changing the voltage pattern on the electrodes.
摘要翻译： X射线检查包括用于通过X射线照射被检体（例如待检查患者）来限制在X射线检测器上形成的X射线图像的动态范围的滤波器。该过滤器具有许多电极和含有X射线吸收材料并悬浮在悬浮液中的颗粒或粉末颗粒。当对电极施加电压时，悬浮液中的X射线吸收材料将在电泳的影响下移动到激发电极。通过施加合适的电压图来调整具有期望的X射线吸收曲线的分布。电极可以具有例如0.5×0.5mm的尺寸，使得能够以高空间分辨率获得X射线吸收曲线。可以通过改变电极上的电压图案在短时间内（例如在1秒钟内）来改变X射线吸收曲线。
