An equidensometric procedure is presented for achieving objective evaluation of ultrasonic B-scan pictures. Using special film (Agfacontour film) it is possible to select and show individually areas of equal brightness appearing on the B-scan, so called "equidensites". This can be done by colouring each area differently or by using a system of symbols. There is a description of the way in which the Agfacontour film works and is processed. Clinical evidence can be provided to prove the equidensometric evaluation of ultrasonic B-pictures of the eye can offer a considerable amount of additional information.
本文介绍了一种用于对超声B扫描图像进行客观评估的等密度测量方法。使用特殊胶片（爱克发轮廓胶片），可以选择并单独显示出现在B扫描中的等亮度区域，即所谓的“等密度区”。这可以通过对每个区域进行不同颜色的着色或使用符号系统来实现。文中描述了爱克发轮廓胶片的工作方式及处理方法。可以提供临床证据来证明对眼部超声B图像的等密度测量评估能够提供大量额外信息。
