The dicomizer program splits the DICOM multi-frame image instance into multiple parts and assigns each part a separate SOPInstanceUID:

These instances are not compliant with the standard.



According to PS3.3 Section C7.6.16, each “concatentation” part \(which contain subsets of frames\) must contain the following attributess

* Concatenation UID
* Concatenation Frame Offset Number
* In-concatenation Number
* SOP Instance UID of Concatenation Source

See http://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_C.7.6.16.html#table_C.7.6.16-1
