Hello,
I'm new to this community and to DICOM, and first of all I would like to thank you all for your great answers in here. It has been a great help for me.
My question: In the MWL query response specification, the attribute "scheduled procedure step sequence" in table Table K.6-1 in part 4 [1] has the remark: "The Scheduled Procedure Step Sequence shall contain only a single Item."
I'm confused by this, since I've read in many places that the relationship between Requested Procedures and Scheduled Procedure Steps is one-to-many.
The only way I could make sense of it so far would be that since this query is coming for a single modality, and the one-to-many would be serving the use case where a study is to be created by many modalities, that there would be a single SPS for each modality, therefore a single element in there for each modality.
I have read somewhere else that there is the use case that a RP would have two SPS for the same modality, for example with different protocols. That would void my explanation.
Does anybody have some idea how to interpret that remark?
Thanks & best,
Alon
