在常规投照方法中 ,需使用角度板投照的体位是将暗盒直接放在角度板上 ,患部与床面成一定角度 ,球管不加角度的条件下完成的 ,由于角度板材料自身的影响 ,投照时不能同时使用滤线器 ,使得投照条件不易把握 ,影像灰雾度大 ,照片质量长期得不到提高 ,为此我们自制了能在滤线器条 In the conventional projection method, the position to be projected using the angle plate is to place the cassette directly on the angle plate, the affected part is at an angle to the bed surface, and the spherical tube is completed without angle. Since the angle plate material itself Impact, Projection can not use the filter at the same time, making the projection conditions is not easy to grasp, the image foggy, long-term photo quality can not be improved, for which we made in the filter bar
