Conversion workflow
March 2013 DICOM International Conference & Seminar Enhanced family of Image SOP Classes 26
Heterogeneous environment with conversion from single to multi-frame objects
Conversion
Why conversion• Enormous archive of Classic objects• Supports the transition from Classic to
Enhanced environment• More often used on different places• Transportation needs speeding up• Leverage most of the benefits
March 2013 DICOM International Conference & Seminar Enhanced family of Image SOP Classes 27
Conversion
Requires• Conversion done by independent
stations• Build knowledge for various vendors• Relaxation of Manditoriness

Conclusion
• Huge potential benefit for using Enhanced objects
• Support is growing• Pushed by
• Increased Interoperability• Increasing datasets• Potential Speed gain• Higher availability• Coming conversion definition
