Software Services Delivered from the Cloud

Abstract

Picture Archiving and Communication Systems (PACS), alongside Radiological Information Systems (RIS) are nowadays widely disseminated, proven useful, hospital information systems components. The “Région Sans Film” (“Filmless Region”) program was launched in 2009 by the French ministry of health in order to help the generalization to all healthcare structures such as hospitals or general physician practices, of PACS, RIS, and archiving of medical images. It is done by means of a mutualized service platform whom building and running has been entrusted to an industrial consortium. This platform implements the latest technologies of medical image processing and of cloud computing. It is built in order to support service-oriented enterprise architecture composed of one main layer of software services. This natively scalable platform is innovative because it is the first one which contains all the materials for the implementation of all services in the cloud. The corresponding SLA are defined in order to be adaptable to the needs of further health structures which could later join the platform by participating in its mutualized purchasing. The goal is not only to share the costs but also to deliver new images sharing services. New business processes/services around sharing of images such as teleradiology or access to the images produced in hospitals to the general practitioners are defined towards the exercise of real filmless radiology.
