movescu: DICOM retrieve (C-MOVE) SCU


movescu [options] peer port [dcmfile-in...]


The movescu application implements both an SCU for the Query/Retrieve Service Class and an SCP for the Storage Service Class. movescu supports retrieve functionality using the C-MOVE message. It sends query keys to an SCP and awaits responses. It will accept associations for the purpose of receiving images sent as a result of the C-MOVE request. The application can be used to test SCPs of the Query/Retrieve Service Class. The movescu application can initiate the transfer of images to a third party or can retrieve images to itself. Note that the use of the term "move" is a misnomer. The C-MOVE operation actually performs an image copy (no images will be deleted from the SCP).

Each file supplied on the command line will be sent to the SCP as part of a C-MOVE request. The query file must be a valid DICOM data set containing the dataset part of a C-MOVE-RQ message. The query file could, for instance, be created with the dump2dcm utility from a script like the following example:

# request all images for the patient with ID=PAT001
(0008,0052) CS [PATIENT]     # QueryRetrieveLevel
(0010,0020) LO [PAT001]      # PatientID

Individual attributes of each file sent can be modified or supplemented using the -k (or –key) option. For example the command:

movescu -k 0010,0020=PAT002 caesar 5678 patqry.dcm

will, when sent to the SCP caesar at TCP/IP port 5678, cause any PatientID attribute in patqry.dcm to have the value 'PAT002'. If such an attribute is present it will be replaced, if absent it will be inserted. The -k option can be present more than once. The value part (after the '=') may be absent causing the attribute to be sent with zero length. It is not possible to replace or insert attributes within sequences using the -k option.

If no file is specified on the command line, the query must be specified completely with one or more -k options. If multiple query files are provided, movescu will send multiple C-MOVE requests to the SCP.

For all uses of movescu, the SCP must be configured to "know" about the AE title where the images are to be transmitted. This is required since the C-MOVE request only contains the AE Title of the target and the SCP must be able to convert this AE Title into TCP/IP address and port number in order to actually send the images over a separate association.

The C-MOVE operation of the Query/Retrieve Service Class is able retrieve images (when option –port is used) or to initiate a copy of images to a third party.

Known Problems

movescu is intended to be used as a testing tool for DICOM software developers. The query keys file must be created by hand based upon the contents of the SCP.

The movescu application makes no attempt to prevent incorrect queries. In particular, the query keys of a C-MOVE request should only contain the QueryRetrieveLevel attribute and one or more of the so-called "unique key attributes" (PatientID, StudyInstanceUID, SeriesInstanceUID and SOPInstanceUID).

In case the storage client does not end the connection while movescu is playing the role of the storage server (i. e. the –port is used) but the client instead expects movescu to close down the storage connection, movescu will wait infinitely. In that case movescu will neither close the association that was used to issue the C-MOVE request to the C-MOVE server.

DICOM Conformance

SCU Conformance

The movescu application supports the following SOP Classes as an SCU:

MOVEPatientRootQueryRetrieveInformationModel         1.2.840.10008.
MOVEStudyRootQueryRetrieveInformationModel           1.2.840.10008.
MOVEPatientStudyOnlyQueryRetrieveInformationModel    1.2.840.10008.

The movescu application will propose presentation contexts for one of the abovementioned supported SOP Classes depending on the command line options (-P, -S, or -O). It will also propose the corresponding SOP Class from the following list, although it is not really used (this is a relict of the RSNA'93 demonstration):

FINDPatientRootQueryRetrieveInformationModel         1.2.840.10008.
FINDStudyRootQueryRetrieveInformationModel           1.2.840.10008.
FINDPatientStudyOnlyQueryRetrieveInformationModel    1.2.840.10008.

For outgoing associations, the following transfer syntaxes are supported:

LittleEndianImplicitTransferSyntax                   1.2.840.10008.1.2
LittleEndianExplicitTransferSyntax                   1.2.840.10008.1.2.1
DeflatedExplicitVRLittleEndianTransferSyntax         1.2.840.10008. (*)
BigEndianExplicitTransferSyntax                      1.2.840.10008.1.2.2

(*) if compiled with zlib support enabled (see –version output)

Which transfer syntaxes are actually proposed in what order, can be specified with the –propose options.

The movescu application will usually accept presentation contexts for all of the abovementioned supported SOP Classes using any of the following transfer syntaxes:

LittleEndianImplicitTransferSyntax                   1.2.840.10008.1.2
LittleEndianExplicitTransferSyntax                   1.2.840.10008.1.2.1
BigEndianExplicitTransferSyntax                      1.2.840.10008.1.2.2

When acting as an SCP, the movescu application will prefer transfer syntaxes having an explicit encoding over the default implicit transfer syntax. If movescu is running on big-endian hardware it will prefer BigEndianExplicit to LittleEndianExplicit transfer syntax (and vice versa). This behavior can be changed with the –prefer options (see above). Using option –accept-all any of the following transfer syntaxes is supported:

LittleEndianImplicitTransferSyntax                   1.2.840.10008.1.2
LittleEndianExplicitTransferSyntax                   1.2.840.10008.1.2.1

(*) if compiled with zlib support enabled (see –version output)

The movescu application does not support extended negotiation.

Access Control

When compiled on Unix platforms with TCP wrapper support, host-based access control can be enabled with the –access-control command line option. In this case the access control rules defined in the system's host access control tables for movescu are enforced. The default locations of the host access control tables are /etc/hosts.allow and /etc/hosts.deny. Further details are described in hosts_access(5).


movescu --patient --port 9876 --move TEST_AE --call ARCHIVE caesar 104 q.dcm

sends the attributes contained in the DICOM file "q.dcm" as part of a C-MOVE request to application entity ARCHIVE on the host caesar at port 104 using the Patient Root query model. movescu itself uses the default AE title MOVESCU. The C-MOVE request will specify that images should be transferred to the destination AE title TEST_AE (via the –move option). How the SCP interprets this request depends on its configuration. movescu will listen on part 9876 for incoming associations in order to receive the requested images from the SCP.

Images can be copied to a third party by using a different destination AE title (e.g. –move ANOTHER_AE). Of course, the SCP must "know" this AE title and the destination must be acting as an SCP of the Storage Service Class (the storescp application can be used for this purpose).


The level of logging output of the various command line tools and underlying libraries can be specified by the user. By default, only errors and warnings are written to the standard error stream. Using option –verbose also informational messages like processing details are reported. Option –debug can be used to get more details on the internal activity, e.g. for debugging purposes. Other logging levels can be selected using option –log-level. In –quiet mode only fatal errors are reported. In such very severe error events, the application will usually terminate. For more details on the different logging levels, see documentation of module "oflog".

In case the logging output should be written to file (optionally with logfile rotation), to syslog (Unix) or the event log (Windows) option –log-config can be used. This configuration file also allows for directing only certain messages to a particular output stream and for filtering certain messages based on the module or application where they are generated. An example configuration file is provided in <etcdir>/logger.cfg.


All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values.

Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behavior conforms to the standard evaluation rules of common Unix shells.

In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator unless they appear between two quotation marks) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows one to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file <datadir>/dumppat.txt).


The movescu utility uses the following exit codes when terminating. This enables the user to check for the reason why the application terminated.


EXITCODE_NO_ERROR                         0
EXITCODE_SETUID_FAILED                    3

output file errors


network errors

EXITCODE_CMOVE_WARNING                   68
EXITCODE_CMOVE_ERROR                     69


The movescu utility will attempt to load DICOM data dictionaries specified in the DCMDICTPATH environment variable. By default, i.e. if the DCMDICTPATH environment variable is not set, the file <datadir>/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).

The default behavior should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (":") separates entries. On Windows systems, a semicolon (";") is used as a separator. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
