Information infrastructures involve the notion of a shared, open infrastructure, constituting a space where people, organizations, and technical components associate to develop an activity. The current infrastructure for medical image sharing, based on PACS/DICOM technologies, does not constitute an information infrastructure since it is limited in its ability to share in a scalable, comprehensive, and secure manner. This paper proposes the DICOMFlow, a decentralized, distributed infrastructure model that aims to foment the formation of an information infrastructure in order to share medical images and teleradiology. As an installed base, it uses the PACS/DICOM infrastructure of radiology departments and the internet e-mail infrastructure. Experiments performed in real and simulated environments have indicated the feasibility of the proposed infrastructure to foment the formation of an information infrastructure for medical image sharing and teleradiology.Keywords Digital imaging and communications in medicine (DICOM) .

An Information Infrastructure (II) provides a space for information sharing and collaboration that allows the spontaneous association of people, organizations and technological components located in different geographical contexts to develop some activity. II do not originate from projects specified a priori, its formation occurs through the evolution of an installed base. The current teleradiology infrastruc-ture does not yet constitute an II for radiological practice, as the inertia present in its installed base hampers its evolution. This paper presents DicomFlow, a decentralized architectural model, built on the email and PACS-DICOM infrastructures, which uses this very inertia to promote the formation of an II for radiological practice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
