C-FIND for 1nst InstanceNumber

[martinrame]

Hi, I'm developing an app that requires accessing only one image (for example the first in a series) to create a thumbnail using WADO.

I can get the list of all SOPInstanceUIDs by issuing a C-FIND similar to this:

Code: Select all

findscu -aet MYAET -aec PACSAET --study -k "0008,0052=IMAGE" -k "0020,000D=1.3.46.670589.11.32401.5.0.8408.2011060323243518864" -k 
"0020,000E=1.3.46.670589.11.32401.5.0.6896.2011060323294317672 " -k "0008,0018"  192.168.0.120 104

I wonder if I can safely get only one instance from the pacs, for example by filtering InstanceNumber (or other tag):

Code: Select all

findscu -aet MYAET -aec PACSAET --study -k "0008,0052=IMAGE" -k "0020,000D=1.3.46.670589.11.32401.5.0.8408.2011060323243518864" -k 
"0020,000E=1.3.46.670589.11.32401.5.0.6896.2011060323294317672 "-k "0008,0018" -k "0020,0013=1" 192.168.0.120 104

This query gets the SOPInstance whose InstanceNumber is 1, but I think that's not guaranteed by the modality, please correct me if I'm wrong.

Hi Martin,

looks good to me. Note that some PACS do not support IMAGE level queries at all (even if they have to if they support study root which you use).

Best,
Michael
