NAME

movescu - DICOM retrieve (C-MOVE) SCU

SYNOPSIS

movescu [options] peer port [dcmfile_in...]

DESCRIPTION

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).

NOTES

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 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 key' options.

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 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.; Even when using a third-party move it may be necessary to set the TCP/IP port number to a reasonable value (via the --port option). Per default, port number 104 is used which is a restricted port on many systems. movescu always tries to listen for incoming associations.; 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).

The movescu application will accept presentation contexts for all of the abovementioned supported SOP Classes using any of the 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 BigEndianExplicitTransferSyntax to LittleEndianExplicitTransferSyntax (and vice versa). This behaviour can be changed with the --prefer options (see above).; 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).

EXAMPLES

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 specifiy 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).

COMMAND LINE

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 behaviour 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) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).

ENVIRONMENT

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 <PREFIX>/lib/dicom.dic will be loaded unless the dictionary is built into the application (default for Windows).

The default behaviour 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. 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.
