Medical image sharing is an important problem in modern radiology, with wide applications in Internet and mobile devices. Some important features need to be added and optimized to medical image sharing. In this paper, we present an extensible Web Access to DICOM Persistent Objects (WADO) middleware based on image cache and real-time Web monitor technology for regional medical image sharing. We first develop the extension method of WADO standard and workflow of extended WADO service. Then, we design a medical image cache method to improve the performance of medical image on-demand transmission. Using the real-time monitor can discover the performance bottlenecks and optimized critical points. The experimental results show that the middleware effectively delivers medical images and reports to Web clients over the Internet, regardless of the platform used for access. It can be deployed in one hospital to provide WADO service to medical workers and also can be applied to regional picture archiving and communication systems (PACS) to transmit medical images and reports to Internet users in a way that is transparent to end-user applications.
医学图像共享是现代放射学中的一个重要问题，在互联网和移动设备中有广泛应用。需要为医学图像共享添加并优化一些重要特性。在本文中，我们提出了一种基于图像缓存和实时网络监控技术的可扩展的医学数字成像和通信系统（DICOM）持久对象的网络访问（WADO）中间件，用于区域医学图像共享。我们首先开发了WADO标准的扩展方法和扩展WADO服务的工作流程。然后，我们设计了一种医学图像缓存方法，以提高医学图像按需传输的性能。使用实时监控可以发现性能瓶颈和优化关键点。实验结果表明，该中间件能够通过互联网有效地将医学图像和报告传送给网络客户端，而不管用于访问的平台是什么。它可以部署在一家医院，为医护人员提供WADO服务，也可以应用于区域图像存档与通信系统（PACS），以一种对终端用户应用透明的方式将医学图像和报告传输给互联网用户。
