Hi,
I am a newbie with dcmtk.

I have setup a DICOM server (conquest). I have inserted a few
dicom images into it. These are also viewable from itz web-interface.
I have a patient named `b_1tumour'.

I want to see this result with findscu. Please help me as to how to use it.
I referred to its man page. However, I am not able to understand what is
`dcmfile_in' dicom file.

Please help.
thanks!

... then you didn't read the NOTES section of the man page - at least not very carefully.

Hi again,

I went through the NOTES section carefully.
But the problem is that I dont get a response back from the dicom server.

I have a conquest running on localhost on port 5678. It
has data. I want to find the patient by the name `Patient_001^G_001'
My request file looks like following (which i call `req')

# query patient names and IDs
# (0008,0052) CS [PATIENT] # QueryRetrieveLevel
# (0010,0010) PN [Patient_001^G_001] # PatientName
# (0010,0020) LO [1190252445] # PatientID
I converted `req' to `req.dcm' with `dump2dcm'

After that, I have used the following command
findscu -P localhost 5678 req.dcm

However, I dont get any response from the server on this.
Please help me..

Hi,

Your query looks good, in general. I guess you are also sure that you use the correct patient ID, right? (then you do not need to send the patient name, anyway).

Please use -v and -d option in findscu and then insert the log in the forum so we see what is going on in case you do not understand the error given.

Best regards,
Michael

Hi,

well, seems like it works

This is your response:

# Used TransferSyntax: LittleEndianImplicit
(0000,0002) UI =FINDPatientRootQueryRetrieveInformationModel # 28, 1 AffectedSOPClassUID
(0000,0100) US 32800 # 2, 1 CommandField
(0000,0120) US 1 # 2, 1 MessageIDBeingRespondedTo
(0000,0800) US 258 # 2, 1 DataSetType
(0000,0900) US 65280 # 2, 1 Status
DIMSE receiveFileData: 34 bytes read (last: YES)
RESPONSE: 1 (Pending)

# Dicom-Data-Set
# Used TransferSyntax: LittleEndianExplicit
(0008,0052) CS [PATIENT ] # 8, 1 QueryRetrieveLevel
(0010,0020) LO [1190252445] # 10, 1 PatientID

The response after that with status SUCCESS is always returned last, so one patient is found exactly.

Michael

P.S: You can also use option "-X" to write all responses to response files (rsp0001.dcm, ...) in DICOM format.

swaroopcool21 · #7 Post by **swaroopcool21** » Thu, 2011-03-24, 15:32

tried this,
with -X
findscu -X ew.dcm -d -v -P localhost 5678 req.dcm

but it gives error
"error: Invalid parameter value localhost"

please help with this options..

#8 Post by **Jörg Riesmeier** » Thu, 2011-03-24, 16:07

The -X option does not expect a parameter since the filenames are generated automatically:

Code: Select all

  -X    --extract
          extract responses to file (rsp0001.dcm, ...)

So your call to findscu is incorrect. The correct call would be:

Code: Select all

findscu -X -v -d -P localhost 5678 req.dcm

DICOM @ OFFIS

findscu

findscu
