"Chapter 6" 75 pagina's3.644 elements
• File format NOT an object model!
• Not normalized
DicomObject
All 3.644 attributes
• Flat structure (well, some of the datatypes are complex)
• Sets of key/value pairs• "All DICOM Objects must
include Patient, Study, Series and Image"
• FHIR: Focus on "registry" function/searching
Biggest Challenge:
Granularity
QIDO-RS

QIDO-RS and then WADO-RS

Secondary Challenges
Composition/reference• DICOM – composition only
Syntax• DateTime -> date+time• Approx. 25 datatypes need
to be converted
Now, I'll just have to finish doing it!
