The Web Access to Digital Imaging and Communication in Medicine (DICOM) Persistent Objects (WADO) service is standardized as the Web extension to DICOM. This paper analyzes the operational specifications of the WADO service and extends its access capability to the whole DICOM hierarchy (patient, study, series, and object). The proposed Web Access to DICOM Archives (WADA) service, as opposed to WADO, also includes an extrainternal query mechanism and support of medical reports submission. A pilot implementation of WADA as software components and their integration into a three-tier architecture are also presented. Advanced security mechanisms are augmented to ensure communication encryption, user identification, and access restriction to data according to user roles. The proposed service is a simple approach, and can be embedded in any system managing medical images and reports. WADA can also be integrated into the Cross-Enterprise Document Sharing-Imaging (XDS-I) standard, which is considered to be the most likely future standard for medical imaging exchange.
医学数字成像和通信（DICOM）持久对象的网络访问（WADO）服务被标准化为DICOM的网络扩展。本文分析了WADO服务的操作规范，并将其访问能力扩展到整个DICOM层次结构（患者、研究、系列和对象）。与WADO不同，所提出的医学数字成像和通信档案的网络访问（WADA）服务还包括一个外部查询机制和对医学报告提交的支持。还介绍了WADA作为软件组件的试点实施及其在三层架构中的集成。增强了先进的安全机制，以确保通信加密、用户识别以及根据用户角色对数据的访问限制。所提出的服务是一种简单的方法，可以嵌入到任何管理医学图像和报告的系统中。WADA还可以集成到跨企业文档共享-成像（XDS-I）标准中，该标准被认为是医学成像交换最有可能的未来标准。
