CDs shall have a human-readable identification on the outside of the physical medium

Recommendations: Patient Name Media Creation Date Name of the Originating Institution Indication of the Content Type:

“DICOM ONLY” or“DICOM PLUS WEB”


Actors Interchanging DICOM Information Shall Use theSTD-GEN-CD Media Storage Application Profile

Non-DICOM Content Shall NOT be Placed in the DICOM Directory

All DICOM File Names are Limited to Only:– 8 Characters (NO Extensions),– Uppercase Letters,– Digits and– Underscore

DICOM Part 10 Compliance – Validated by the MESA Test Tools

CDROM RulesCDROM Rules– DICOM Content –– DICOM Content –


IHE_PDI web content corresponds exclusively to the DICOM content, although it need not represent the entire DICOM content

Web content use of XHTML and JPEG formats is restricted to ensure interoperability

Non-web content will not be placed in IHE_PDI directories, but may be placed in other locations on the CDROM

All file names are restricted to the ISO 9660 8.3 file name
