Queries for C Find Request to PACS

[harithacha...@gmail.com]

Hi all,

 i have couple of queries regarding C Find SCU.

 

 1. When we want to query PACS based on multiple modalities i.e if we want studies from CT ,  MR, NM for a particular date range . Is it right to use this CT\MR\NM. Is slash the correct way to fetch multiple ones?

 2. Also according to DICOM standards , can we query based on study description?

Please help with the above queries.

Thanks,

Haritha C Mouli

Yes, but provide it in quotes

findscu -c DCM4CHEE@localhost:11112 -m "ModalitiesInStudy=CT\MR\NM"

 2. Also according to DICOM standards , can we query based on study description?

Yes. See Study Level Keys for the Study Root Query/Retrieve Information Model. Dcm4chee archive v5.x supports it.

Thank you for your quick reply. 

Also an addition to the previous question. If we want to query on multiple study description values will it be the same as how you mentioned for modality? Like,  "StudyDescriptoon = Sinus\No description"

And if there is a CFind request like :

findscu -c DCM4CHEE@localhost:11112 -m "ModalitiesInStudy=CT\MR\NM"  -m "StudyDescriptoon = Sinus\No description"

On what basis will the results be queried from pacs?

No, this is not possible. Study Description is an attribute on study level. So you may provide either direct values in matching keys or use wildcard matching

findscu -c DCM4CHEE@localhost:11112 -m "ModalitiesInStudy=CT\MR\NM"  -m StudyDescription=Sinus

or

findscu -c DCM4CHEE@localhost:11112 -m "ModalitiesInStudy=CT\MR\NM"  -m StudyDescription=Si*

Using multiple values for matching keys other than of Value Representation "UI" is a proprietary extension of dcm4chee-arc. Such C-FIND RQ's are not compliant with DICOM and you would have to be lucky, if they get accepted and processed with OR semantic by other DICOM archive implementation!

Thanks Vrinda. 

ModalitiesInStudy tag is also an attribute  on study level right? so was wondering based on what criteria we can do multiple search on  ModalitiesInStudy  and not on  StudyDescription.
