传统的射线照相仍然是记录X射线图像的最有价值的方法。白色减影大大提高了动脉造影的质量。加色减影是标准X线减影的一种修饰。它是一种对医学教材和医学教学有特殊价值的显示方法。下面概述的方法代表了一种制作加色射线照片的新简化技术。该程序的重要性在于它简单且相对便宜。色彩呈现的质量非常出色。该方法与前面描述的工艺（1，4-6）的显著不同之处在于，它是接触过程并且能够产生上级射线照相细节。方法以要点的形式总结了彩色加减片的制作技术：一、初始白色减影A、掩模制作1.将一张柯达商业胶片（Estar厚片基），乳剂面朝上，放置在胶片上，然后将胶片的感光面与胶片的感光面接触，然后将胶片的感光面与胶片的感光面接触。
Conventional radiographs remain the most valuable method of recording the x-ray image. Black-and-white subtraction has greatly enhanced the quality of arteriographic studies. Color-additive subtraction is an embellishment of the standard radiographic subtraction. It is a display method of particular value for medical illustrative material and medical teaching. The method outlined below represents a new simplified technic of producing color-additive radiographs. The procedure is significant in that it is simple and relatively inexpensive. The quality of color presentation is excellent. The method is significantly different from the previously described technics (1, 4-6) in that it is a contact process and is capable of producing superior radiographic detail. Method The technic used for producing color-additive subtraction films is summarized in point form as follows: I. Initial Black-and-White Subtraction A. Mask Production 1. Place a sheet of Kodak commercial film (Estar thick base), emulsion side up, ...
