通常的静电X光摄影,其主要缺点是感光板对X射线不够灵敏。为了克服这一不足,我们研究了一种高度灵敏的静电X光摄影方法。所采用的感光板系积层形式:由外绝缘层,多层光导层、内绝缘层、透明电极和荧光体层构成。该方法通过二步电晕充电,在外绝缘层上形成静电潜像。 通过这种方法,我们成功地大幅度提高了感光层的光敏性。有可能象通常的X光胶片那样利用荧光体层的发光。附有荧光体层的感光板,X射线灵敏度与X光胶片接近。 用在医疗上,使用普通的X光管,当管电压为40~50千伏峰值电压及辐照量为40~70毫安秒时,就能获得乳房、胸、甲状腺、骨骼和皮肤等的清晰图像。
The main disadvantage of the usual electrostatic X-ray photography is that the plate is not sensitive enough to X-rays. In order to overcome this problem, we studied a highly sensitive electrostatic X-ray photography method. The plate used in the laminated form: the outer insulation layer, multilayer light guide layer, the inner insulating layer, the transparent electrode and the phosphor layer. The method forms a latent electrostatic image on the outer insulating layer by a two-step corona charging. In this way, we succeeded in drastically increasing the photosensitivity of the photosensitive layer. It is possible to utilize the luminescence of the phosphor layer like the usual X-ray film. Fluorescent layer attached to the plate, X-ray sensitivity and X-ray film close. Used in medicine, the use of ordinary X-ray tube, when the tube voltage is 40 to 50 kV peak voltage and the irradiation of 40 to 70 milliamps seconds, you can get the breast, chest, thyroid, bone and skin, etc. Clear image.
