Querying with findscu

rexford.newbould · Mar 8th 2007

So I have a conquest server happily running under linux using mysql. I can happily send images to the database, and they are properly stored, and can be found via a search.

If I want to list the studies on the server using the dcmtk's findscu, I can do it with:

Code

findscu -v -S -k 0009,1002= -k 0010,0010= -k 0010,0020= -k 0008,1030= -k 0008,0020= -k 0020,0010= -k 0008,0052=STUDY -k 8,20= -k 8,30= -k 0020,000D= -aec conquest servername 5678

This gives me back 86 responses (for 86 studies currently in the DB), but each response is using the UN field code, and spitting out ASCII codes:

Code

# Dicom-Data-Set# Used TransferSyntax: LittleEndianExplicit(0008,0020) UN 32\30\30\36\30\39\31\34                  #   8, 1 StudyDate(0008,0030) UN 31\31\33\32\34\36                        #   6, 1 StudyTime(0008,0052) UN 53\54\55\44\59\20                        #   6, 1 QueryRetrieveLevel(0008,1030) UN 4d\52\20\42\52\41\49\... #  14, 1 StudyDescription(0010,0010) UN 57\49\54\... #  16, 1 PatientsName(0010,0020) UN 31\36\32\...            #  10, 1 PatientID(0020,000d) UN 31\2e\32\2e\31\32\34\2e\31\31\33\35\33\32\... #  52, 1 StudyInstanceUID(0020,0010) UN 32\36\35\35\33\20                        #   6, 1 StudyID

(I added the ... to replace possibly identifying fields)

This seems to be stopping Osirix and e-film from properly qurying the server, as every other (nonConquest) dicom server I query responds back knowing the field codes and using real ASCII. Here's one of many examples:

Am I missing a dicom dictionary somewhere? Can I specify a specific response syntax?

Thanks for the help,
Rex

Have a look at dgatesop.lst and comment out LittleEndianExplicit if it is not. This variable is different in the default dgatesop.lst in the linux and windows versions

Hey wow, thanks Mark, that worked.
