NAME

       gdcmscu - Tool to execute a DICOM Query/Retrieve operation

SYNOPSIS

       gdcmscu [OPTION]...[OPERATION]...HOSTNAME...[PORT]...

	Execute a DICOM Q/R operation to HOSTNAME, using port PORT (104 when not specified)

DESCRIPTION

       The gdcmscu command line program is the tool to execute DICOM Query/Retrieve operation. It supports:

       o C-ECHO (SCU)
       o C-FIND (SCU)
       o C-STORE (SCU)
       o C-MOVE (SCU/SCP) C-MOVE operation are executed using two different ports (one for the SCU and one for the SCP).

C-ECHO usage
       gdcmscu is a great tool to test if a DICOM server is up. For example to send a C-ECHO to server dicom.example.com using port 104, use:
       $ gdcmscu dicom.example.com
       or if you prefer being explicit:
       $ gdcmscu --echo dicom.example.com 104
       Using basic security your DICOM server might require that you set the appropriate called AE-TITLE
       $ gdcmscu --echo dicom.example.com 11112 --call SERVSCP
       If you want to specifiy your own AE-TITLE (default is GDCMSCU), simply use:
       $ gdcmscu --echo dicom.example.com 11112 --call SERVSCP --aetitle MYSCU
       For example you could test on the DICOM server provided by DICOMObject team:
       $ gdcmscu www.dicomserver.co.uk 11112
C-STORE usage
       C-STORE is the operation that allow sending a DICOM file to a remote DICOM server. For instance to send a file called myfile.dcm
       $ gdcmscu --store dicom.example.com 104 myfile.dcm
       or if you prefer being explicit:
       $ gdcmscu --store dicom.example.com 104 -i myfile.dcm
       You can even send multiple files using the same association:
       $ gdcmscu --store dicom.example.com 104 myfile1.dcm myfile2.dcm myfile3.dcm ...
C-FIND usage
       gdcmscu also allow querying a DICOM server. This is the C-FIND operation, for example to find all DICOM Instance where PatientsName match a
       particular pattern, usage is simply:
       $ gdcmscu --find --patient dicom.example.com 11112 --patientroot --key 10,10,"A*"
       We also support a DCMTK compatible convention:
       $ gdcmscu --find --patient dicom.example.com 11112 --patientroot --key 10,10="A*"
       When an attribute is set without a value it will be part of the output result:
       $ gdcmscu --find --patient dicom.example.com 11112 --call MI2B2 --patientroot -k 10,10="A*" -k 10,20
C-MOVE usage
       C-MOVE is the operation to retrieve a DICOM instance from a remote DICOM server. Most of the time, it is a subsequent operation after a C-
       FIND query. To retrieve a DICOM instance where PatientID is ABCD1234, simply execute:
       $ gdcmscu --move --patient --aetitle ACME1 --call ACME_STORE dicom.example.com 5678 --patientroot -k 10,20="ABCD1234" --port-scp 1234
       WARNING For this operation to work you need information from the DICOM server you are communicating with. Only the DICOM server you are
       sending a C-MOVE query will be reponsible for sending back incoming associations (the actual C-STORE SCP). Therefore you need to make sure
       that you mapping of (AE-TITLE,PortNumber) is properly set on the DICOM server side as well as the port for incoming association (--port-
       scp).
       gdcmscu does not currently support external C-STORE association (C-STORE request sent to an external SCP application).
patientroot notes
       The flag --patientroot is just simply a wrapper around the syntax --key 8,52=PATIENT For instance one would write using DCMTK syntax:
       findscu --patient dicom.example.com 11112 --key 8,52=PATIENT --key 10,10="F*"
       This would become using GDCM syntax:
       $ gdcmscu --find --patient dicom.example.com 11112 --patientroot --key 10,10="F*"
Debugging
       This is sometime difficult to investigate why a connection to a remote DICOM server cannot be done. Some recommendations follows:
       Always try to do a simple C-ECHO at first. If you cannot get the C-ECHO to work none of the other operations will work
       Before trying to a C-MOVE operation, make sure you can execute the C-FIND equivalent query first.
       When doing a C-MOVE operation you really need to communicate with the PACS admin as the C-MOVE operation is different from the other lower
       level operation such as HTTP/GET. When doing a C-MOVE, the server will communicate back using another chanel (could be different port)
       using it's internal database to map an AE-TITLE back to the destination IP. Indeed the C-MOVE operation by design does not always use your
       incoming IP adress to send back the resulting dataset. Instead it uses a mapping of AE-TITLE to IP adress to send back any results. So pay
       particular attention to the spelling of your AE-TITLE and your incoming port (which may be different from the port to connect to the
       server).
Port Warning
       Watch out that port ranging [1-1024] are reserved for admin and not easily accessible unless granted special priviliges. Therefore the
       default 104 DICOM port might be accessible to all your users.
C-STORE Warnings
       When constructing a C-STORE operation, gdcmscu will always use the Media Storage as found in the file to be sent. For encapsulated DICOM
       file (eg. RLE Lossless) the receiving SCP server might not support this compression and will legitemely refuse the C-STORE operation. In
       this case users have to manually convert to a non-compressed form this particular file:
       $ gdcmconv --raw compressed.dcm non_compressed.dcm
C-MOVE Warnings
       At the moment gdcmscu only supports non-compressed transfer syntax. It will always request DataSet using Implicit VR Little Endian Transfer
       Syntax during a C-MOVE operation.
C-FIND IMAGE level (Composite Object Instance)
       One should pay attention that gdcmscu --find and findscu are not completely equivalent. Using gdcmscu --find, all Unique Keys will be added
       automatically. One can therefore execute something like this:
       $ gdcmscu --find --patientroot --image --key 8,18=1.2.3.4.5.6 dicom.example.com 11112
       instead of the more explicit form
       $ gdcmscu --find --patientroot --image --key 8,18=1.2.3.4.5.6 dicom.example.com 11112 --key 10,20 --key 20,d --key 20,e
       This would also be equivalent to:
       $ findscu --patient --key 8,52=IMAGE --key 8,18=1.2.3.4.5.6 dicom.example.com 11112 --key 10,20 --key 20,d --key 20,e
Storing the Query
       It is also possible to store the query:
       gdcmscu --find --patient --patientroot dicom.example.com 11112 --key 10,20="*" --key 10,10 --store-query query.dcm
       One can then check the DataSet values send for the query:
       $ gdcmdump query.dcm
       # Dicom-File-Format

       # Dicom-Meta-Information-Header
       # Used TransferSyntax:

       # Dicom-Data-Set
       # Used TransferSyntax: 1.2.840.10008.1.2
       (0008,0005) ?? (CS) [ISO_IR 192] 				 # 10,1-n Specific Character Set
       (0008,0052) ?? (CS) [PATIENT ]					 # 8,1 Query/Retrieve Level
       (0010,0010) ?? (PN) (no value)					 # 0,1 Patient's Name
       (0010,0020) ?? (LO) [* ] 					 # 2,1 Patient ID
       The Specific Character Set was set to 'ISO_IR 192' as the locale encoding of the system was found automatically by gdcmscu to be UTF-8.
       This means that the following command line will properly setup the Query with the appropriate Charset to be executed correctly:
       $ gdcmscu --find --patient --patientroot dicom.example.com 11112 --key 10,10="*Jerome*"
       the query is always executed on the server side (SCP), some implementations does not support string matching with different Character Set.
