Laboratory for Radiologic Informatics

The Laboratory for Radiological Informatics (LRI) is part of the Department of Radiology at the University of California at San Francisco, School of Medicine. The LRI is involved in the design, implementation, maintenance, and analysis of clinical picture archiving and communications systems (PACS) and other imaging informatics technologies for clinical use, radiological research and teaching applications. The LRI houses the clinical PACS infrastructure including the image cache, long-term optical archive, database, and web server.

About Informatics

Clinical accomplishments from 1996 through 2001 include the continued development of the UCSF PACS with the major objective to minimize the use of film in medical imaging. A commercial PACS purchased from Agfa Corporation has been implemented and provides the acquisition, short and intermediate term images storage and display components. The LRI has implemented a long term, optical archive with its own database and image management software, which couples to the Agfa PACS. This long-term archive contains images acquired prior to the implementation of the Agfa system as well as studies older than 18 months. Softcopy display stations for image interpretation and review have been and continue to be deployed throughout the Department of Radiology and other key image-intensive areas such as the Emergency Department and the Intensive Care Units. Secure, web-based access to studies has been implemented for image retrieval in less intensive locations within the enterprise and for access to images at physicians' homes. Currently there are over 350 users of the clinical PACS web tool.

Research in the LRI is in the general area of medical imaging informatics which encompasses digital image acquisition, processing, display and archival. Specific focuses of the LRI include the development of PACS workflow and management software, digital image processing and analysis, image display devices and graphical user interface design, archival strategies, and clinical radiology information systems (RIS) and databases.

Research Directions

Research in the LRI is in the general area of medical imaging informatics which encompasses digital image acquisition, processing, display and archival. Specific focuses of the LRI include the development of PACS workflow and management software, digital image processing and analysis, image display devices and graphical user interface design, archival strategies, and clinical radiology information systems (RIS) and databases.

Lab focus is on advancing informatics techniques of medical imaging. Steve Wong has focused on developing intrinsic multimodal image fusion techniques for non-invasive surgical planning and diagnosis, image security models and systems using advanced cryptologic technology, and a web-based epilepsy and brain image registry system for clinical neuroscience and neuroimaging research. This registry contains multimodality brain images and associated longitudinal and vertical clinical data from multiple sclerosis, epilepsy surgical planning, and epilepsy radiation treatment. Other effort includes the development of a prototype system of Corba-Java based Multimedia Electronic Medical Record.

Summary, Future Direction, Areas for Improvement

The LRI is involved in the design, implementation, maintenance, and analysis of clinical PACS and other imaging informatics technologies for clinical use, radiological research and teaching applications. The Lab will continue in its focus advancing digital techniques in medical imaging. Areas of emphasis in the future will include the Integrated Healthcare Enterprise (IHE), image processing including computer aided diagnosis, folder management and workflow, and the utilization of PACS for teaching and research applications. New faculty will be recruited to develop Computer Aided Diagnosis (CAD) and Image Analysis, Computation and Display. These emerging areas represent particularly strong opportunities for collaboration and funding through NIBIB. Recruitment of strong candidates would be greatly enhanced by the ability to expand the LRI into the adjacent, underutilized stack space.
