Development of an Electronic Radiologist's Office in a Private Institute¹

¹ From the Centre d'Imagerie Diagnostique, Grand-Chêne 8 bis, CH-1003 Lausanne, Switzerland (J.C.O.); and WDS Technologies, Geneva, Switzerland (R.W., L.B.). Presented as an infoRAD exhibit at the 1998 RSNA scientific assembly. Received February 16, 1999; revision requested April 13; final revision received September 14; accepted September 23.

A computer system that improves the quality, user-friendliness, accessibility, and management of radiology data (images, reports, databases, knowledge) was implemented at a private institute. A picture archiving and communication system (PACS) was integrated with the radiology information system (RIS). Two servers and 12 personal computers form the integrated system. The first server is dedicated to management and archiving of Digital Imaging and Communications in Medicine (DICOM) images. The second server is dedicated to management of the RIS and archiving of patient data (Structured Query Language database), reports (hypertext markup language [HTML]), and images in the Joint Photographic Experts Group (JPEG) format (mini-PACS). There are three main client-server networks: a common network of imaging modalities (magnetic resonance imaging, computed tomography, ultrasonography, digital radiography) and two fast Ethernet networks (the PACS network and the RIS network). The RIS-PACS is linked remotely with other workstations and servers via Integrated Services Digital Network (ISDN). Images and reports can be distributed to referring physicians in the form of multimedia HTML and JPEG documents, which can also be used for quick and easy archiving, distribution, and reviewing within the institute. However, referring physicians have been reluctant to use electronic reports and images.
