Computers have greatly facilitated the processing and storage of radiologic information. Manufacturers of radiology information systems (RISs) are gradually incorporating options for interfacing their products with other computers (e.g., hospital information systems). However, a growing need exists to also interface RISs with digital radiologic equipment so that images (e.g., computed radiographs of the chest and skeleton) are automatically labeled with identification data. Such connectivity would eliminate redundant work by technologists, decrease errors in the labeling of images, and increase the consistency of patients' data within a radiology department. Unfortunately, the rapid advances in digital technology, combined with the lack of a well-defined standard for the transfer of demographic information between dissimilar systems, have delayed development of these interfaces. We have developed a widely applicable method to automatically transfer patients' demographic data from an RIS to a commercially available computed radiography system. A personal computer is configured with inexpensive programmable telecommunications software to create an interactive gateway, which eliminates the need for redundant data entry (compared with entering data once on the RIS and again on the stand-alone computed radiography system), and thus also decreases errors in the labeling of images.
计算机极大地促进了放射学信息的处理和存储。放射学信息系统（RIS）制造商正逐渐将其产品与其他计算机（如医院信息系统）连接的选项纳入其中。然而，将RIS与数字放射设备连接的需求也日益增长，以便图像（如胸部和骨骼的计算机X线片）能自动标注识别数据。这种连接将消除技术人员的重复工作，减少图像标注中的错误，并提高放射科内患者数据的一致性。不幸的是，数字技术的快速发展，加上不同系统之间人口统计学信息传输缺乏明确标准，延迟了这些接口的开发。我们已经开发出一种广泛适用的方法，可将患者的人口统计学数据从RIS自动传输到商用计算机X线摄影系统。一台个人计算机配置了廉价的可编程电信软件，以创建一个交互式网关，这消除了重复数据输入的需求（与在RIS上输入一次数据，然后在独立的计算机X线摄影系统上再次输入数据相比），从而也减少了图像标注中的错误。
