Status and Timeline

• Interface functionality defined, now time to get to work• SR solutions needed for

– Extracting reports from RIS/Reporting system• UNC Mammography Case Database• Cerner QuadRIS (Chicago)• IDXrad (Penn)

– CAD report generation• Chicago Microcalcification detection• Chicago mass detection• FARgen microcalcification detection

– Relevant clinical history for CAD

• Test solutions in place by end of 2001

We’re looking for:

• SR IODs for testing

• Rendering tools

• Toolkits

• XML-DICOM transcoding tools

• Interoperability testing
