Informatics Section

The Department of Radiology Informatics Section is responsible for strategic planning, implementation, and ongoing operation of information systems in the department. Informatics faculty conduct basic and applied research in the application of information technology to medicine, and provide education to medical students and graduate students in medical informatics.

The Department of Radiology Informatics Section — together with the Decision Systems and Artificial Intelligence Laboratory of the University of Wisconsin-Milwaukee — founded the Medical Informatics and Decision Science (MIDAS) Consortium. Since 1995, the MIDAS Consortium has conducted research and supported education in medical informatics and decision science.

  • Internet-based systems and computer-supported collaborative work



ARRS GoldMiner® - Image Search Engine - ARRS GoldMiner® provides rapid search of a large, Internet-based library of peer-reviewed radiology images.

RadLex® - RadLex® provides a uniform structure for capturing, indexing, and retrieving a variety of radiology information sources, such as teaching files, research data, and radiology reports.

Structured Reporting - The RSNA radiology reporting initiative is improving reporting practices by creating a library of clear and consistent report templates; developing the IHE "Management of Radiology Report Templates" (MRR) standard; and advancing reporting technologies.

Radiology Gamuts Ontology - The Gamuts ontology provides a formal knowledge model of diseases and their imaging manifestations to improve radiological diagnosis.
Information Technology

Information Technology

The Information Technology Team plans, implements, and provides operational support for the Department of Radiology's clinical information systems.

Radiology Information System (RIS)
Our team at Froedtert Hospital currently uses the Radiant RIS from Epic Systems to manage order entry, patient scheduling, exam and film tracking, reporting, and billing.

Picture Archiving and Communication System (PACS)
The team has implemented the McKesson Horizon Medical Imaging PACS, which provides state-of-the-art image storage and display functionality. Currently, all imaging examinations performed in the department — except mammography — are stored on PACS.

All examinations from January 2003 forward are maintained in "active" memory on a Redundant Array of Inexpensive Disks (RAID) server.

Integration with Enterprise Systems
The department supports interfaces of its systems with enterprise-wide clinical information system for order entry, results reporting, laboratory results, and inpatient and outpatient medical records.
