最近引进的LogEtronic接触式打印机为准备模拟彩色X线照片提供了一种简便的方法。正如我们关于模拟彩色X线摄影的初步报告（1）中所指出的，必须首先获得选择用于彩色复制的X线照片的白色底片。从这张底片上，通过接触或放大（通常是后者）到矩阵或泛矩阵胶片上进行曝光。然后通过表I中规定的步骤处理曝光的胶片，以产生用于根据需要添加Flexichrome颜色的明胶浮雕图像。原始底片的质量是最终色彩准备成功的最重要因素之一。一张好的原始底片必须包含并传递所有的定义，这些定义是在最终结果中获得适当的形式和价值所需要的。这个结果是一个彩色X线照片，它尽可能自然地真实地表示所选的X线照片。常规视觉广告.
The recent introduction of the LogEtronic Contact Printer has provided a means of ready simplification in the preparation of simulated color roentgenograms. As indicated in our initial report on simulated color roentgenography (1), it is necessary first to obtain a black and white negative of the roentgenogram selected for color reproduction. From this negative an exposure is made by contact or enlargement, usually the latter, onto Matrix or Pan-Matrix film. The exposed film is then processed, by the steps specified in Table I, to produce a gelatin relief image for the addition of the Flexichrome colors as desired. The quality of the original negative is one of the most important single factors in the success of the final color preparation. A good original negative must contain and transmit all of the definition desired for proper form and value in the final result. This result is a color roentgenogram that realistically represents the selected roentgenogram as naturally as possible. The routine visual ad...
