As PACS and related imaging technologies become more common in the healthcare setting, better methods are needed for training radiologists and allied healthcare providers to understand and use them effectively. In 2001 we demonstrated an educational PACS Simulator that serves such a purpose: in 2002 complete RIS/PACS integration was displayed. In this presentation we will demonstrate a critical new feature of the Simulator. A Web-Based Image Distribution and Display System that completes the clinical PACS workflow. The core Simulator consists of six components: RIS simulator, modality Simulator, DICOM gateway, PACS server, and one clinical viewing workstation. We have now successfully integrated a web distribution and display system. The web server distributes DICOM images to the browser-based display client, allowing display and manipulation of DICOM images. The Simulator has been developed as a stand-alone tool for trainees to understand RIS/PACS concept and appreciate RIS/PACS data flow with hands-on experience. The core Simulator's value has been established in a wide variety training classes, and this addition will significantly improve it.
