Normalizing Heterogeneous Medical Imaging Data to Measure the Impact of Radiation Dose.

The production of medical imaging is a continuing trend in healthcare institutions. Quality assurance for planned radiation exposure situations (e.g.

A framework for integration of heterogeneous medical imaging networks.

Medical imaging is increasing its importance in matters of medical diagnosis and in treatment support. Much is due to computers that have revolutionized medical imaging not only in acquisition process but also in the way it is visualized, stored, exchanged and managed. Picture Archiving and Communication Systems (PACS) is an example of how medical imaging takes advantage of computers.

Screening radiation exposure for quality assurance.

Quality assurance for planned radiation exposure situations (e.g. Digital Radiography, Computed Tomography or Radio Fluoroscopic studies) requires the application of examination-specific scans protocols.

XDS-I outsourcing proxy: ensuring confidentiality while preserving interoperability.

The interoperability of services and the sharing of health data have been a continuous goal for health professionals, patients, institutions, and policy makers. However, several issues have been hindering this goal, such as incompatible implementations of standards (e.g.

A centralized platform for geo-distributed PACS management.

Picture Archive and Communication System (PACS) is a globally adopted concept and plays a fundamental role in patient care flow within healthcare institutions. However, the deployment of medical imaging repositories over multiple sites still brings several practical challenges namely related to operation and management (O&M). This paper describes a Web-based centralized console that provides remote monitoring, testing, and management over multiple geo-distributed PACS.

Enabling outsourcing XDS for imaging on the public cloud.

Picture Archiving and Communication System (PACS) has been the main paradigm in supporting medical imaging workflows during the last decades. Despite its consolidation, the appearance of Cross-Enterprise Document Sharing for imaging (XDS-I), within IHE initiative, constitutes a great opportunity to readapt PACS workflow for inter-institutional data exchange. XDS-I provides a centralized discovery of medical imaging and associated reports.

Enhancing the many-to-many relations across IHE document sharing communities.

The Integrating Healthcare Enterprise (IHE) initiative is an ongoing project aiming to enable true inter-site interoperability in the health IT field. IHE is a work in progress and many challenges need to be overcome before the healthcare Institutions may share patient clinical records transparently and effortless. Configuring, deploying and testing an IHE document sharing community requires a significant effort to plan and maintain the supporting IT infrastructure.

Clustering of distinct PACS archives using a cooperative peer-to-peer network.

To face the demanding requirements of the clinical environment, PACS archives need to be resilient and reliable, supporting high availability and fault tolerance. Often, to ensure no data loss, PACS archives retain two copies of images on separate physical machines, using distributed data storage facilities. However, PACS do not take advantage of the various replicas to improve the transfer rates of medical images.
