A prototype system for digital fluorography (DF) has been developed from commercially available DSA equipment coupled to a standard screening unit. We present our initial clinical experience of this system with particular reference to the ergonomics, the image quality and the effect of image processing. We have concentrated upon dynamic studies such as upper gastrointestinal tract barium studies where the logistic advantages of the system are considerable. We have found DF to be ergonomically more efficient than conventional techniques. Using careful image processing the 512*512 matrix images were considered diagnostic for most studies assessed.
一种数字荧光成像（DF）原型系统是由市售的数字减影血管造影（DSA）设备与标准透视装置组合而成。我们介绍该系统的初步临床经验，特别提及人体工程学、图像质量及图像处理效果。我们着重于动态研究，如在上消化道钡剂造影检查中，该系统在逻辑安排上优势显著。我们发现，在人体工程学方面，DF比传统技术效率更高。通过精细的图像处理，对于大多数评估研究而言，512×512矩阵图像被认为具有诊断价值。
