Medical Imaging Informatics Bench to Bedside (mi2b2) Shawn Murphy MD, Ph.D.
PRINCIPAL AIM FOR CTSC-BIRN PROPOSAL • The purpose of this Administrative Supplement project is to develop and disseminate additions to the Informatics for Integrating Biology and the Bedside (i2b2)-based projects to hospitals that will allow clinical imaging data from sophisticated medical imaging modalities such as MRI, PET, ultrasound and high-speed CT to be used for secondary research purposes.
Enable i2b2 to be used for Image Analysis in CTSC by connecting BIRN/XNAT Query is done To find patients Derive new data from images i2b2 BIRN/XNAT Request Images with Accession #’s Study Images PACS DICOM CFIND DICOM CGET DICOM CSTORE
One of 7 roadmap projects funded by the National Center for Biomedical Computing Open source software for the collection, querying, and analysis of clinical data, trials data, genotypic data, and imaging annotations Software supports large enterprise repositories and specific-purpose project repositories What is the “Informatics for Integrating Biology and the Bedside” (i2b2) project?

Project Task: Enable queries to find patients associated with medical images using i2b2 i2b2 project portal B A C local shared / central “Hive” of software services and core CRC cells Billing Codes remote HL7 Clinical Research Chart
Human Subject Privacy Plan • Follow common plan as for other clinical data types • All patients at a site are added to enterprise repository with HIPAA notification that their data may be used for research upon registration. • General queries produce only aggregated numbers that are obfuscated to prevent identification of individuals • Submit IRB proposal for specific hypothesis & detailed data request for specific set of patients • PI of approved study given identifiable data in secure transfer • IRB can audit all data transfers
Queries can be is performed to return sets of patients with images
Project Task : Enable automated requests for medical images to PACS and copy to XNAT Query is done To find patients Derive new data from images i2b2 XNAT Request Images with Accession #’s Study Images PACS DICOM CFIND DICOM CGET DICOM CSTORE
What is BIRN/XNAT? • An open source BIRN imaginginformatics platform. • Core features: • DICOM workflow • Web interface • Extensible data model • RESTful web services API • Pipeline processing • Built on various open source Java (Jakarta Turbine, Maven, Restlets, dcm4che) and Javascript (YUI) technologies.
XNAT Connects multiple applications throughout BIRN • BIRN Mediator (BIRN-CC) • LONI Pipeline (UCLA) • 3D Slicer (NAMIC)
Project Task: enable progressive annotations to images in i2b2
