合成放大就是将多体位的底片影像放在一张放大纸上,组成一定的构图形式。此方法完善了照片的艺术要求,便于医生对照片诊断和病例保存,既可以节省相纸,又能够缩短暗室的工作时间。1.照片的构思采用伽玛照相机检查的项目很多,不同的检查部位所需要的照片数目不一样,有的一张照片就能做出诊断,有的需要几张、十几张,甚至更多。根据这一情况,我们设计了多种底片放大模具,用于不同检查部位的照片数量要求。这里我们以“一纸九相”为例作以介绍。2.准备工作
Synthetic amplification is the multi-position film image on a piece of paper, composed of a certain composition form. This method improves the artistic requirements of the photos, facilitates the diagnosis and preservation of the photos by the doctors, and can both save paper and shorten the working time of the darkroom. 1. The concept of the photo There are a lot of items to be examined by the gamma camera. The number of photos required by different inspection sites is different. Some photos can make a diagnosis, and some need a few, a dozen or more . Based on this situation, we designed a variety of film amplification molds for the number of different parts of the examination requirements. Here we take “a piece of paper and nine” as an example for introduction. 2. Preparation
