• Data other than images in Cardiology– Procedure Logs– Hemodynamic Data– Electrophysiology Data– QCA/QVA Data

• Electronic copy, rather than paper• Associated with other study data

– Cine-loops– Waveforms

IssuesIssues

• No standard among Cardiology vendors

• Incomplete data• Mapping requires clinical

knowledge of data• Templates are not finalized• DICOM SR not well known among

vendors

SummarySummary

• Template parsing engine extracts template information

• Mapping engine maps data to template

• Templates need to be finalized for all this to work

• Need Template Conformance Statement
