NAME
storescu - DICOM storage (C-STORE) SCU

SYNOPSIS

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

DESCRIPTION

The storescu application implements a Service Class User (SCU) for the Storage Service Class. For each DICOM file on the command line it sends a C-STORE message to a Storage Service Class Provider (SCP) and waits for a response. The application can be used to transmit DICOM images and other DICOM composite objects.

peer        hostname of DICOM peer

port        tcp/ip port number of peer

NOTES

  Scanning Directories
Adding directories as a parameter to the command line only makes sense if option --scan-directories is also given. If the files in the provided directories should be selected according to a specific name pattern (e.g. using wildcard matching), option --scan-pattern has to be used. Please note that this file pattern only applies to the files within the scanned directories, and, if any other patterns are specified on the command line outside the --scan-pattern option (e.g. in order to select further files), these do not apply to the specified directories.

The default behavior of storescu is to propose two presentation contexts for each supported SOP class (abstract syntax) - one with the preferred transfer syntax and one with all other uncompressed transfer syntaxes. The default preferred transfer syntax is explicit VR with byte ordering corresponding to the local byte ordering of the machine on which storescu is running. This behavior can be changed with the --propose, --combine and --required options, see above. Depending on these options, the following transfer syntaxes are supported:

Additional Storage SOP Classes and transfer syntaxes can be used with the so-called 'association negotiation profiles' (see below).

The storescu application does not support extended negotiation by default. However, using an appropriate association negotiation profile (see below) the optional support for extended negotiation can be added to particular SOP classes.

  Association Negotiation Profiles and Configuration Files
storescu supports a flexible mechanism for specifying the DICOM network association negotiation behavior, based on so-called 'association negotiation profiles' which may be read from a configuration file. The format and semantics of this configuration file are documented in asconfig.txt.

  User Identity Negotiation
When specifying user name and/or password using options --user and -e --password, the value has to be provided in UTF-8 encoding.

If the option --pos-response is used, the SCP is asked to explicitly respond, i.e. acknowledge, the user credentials provided in the storescu request. Otherwise, if no such response is sent, storescu will not continue but instead abort the connection. Since User Identity Negotiation is an optional feature that has been introduced later into the standard, many SCPs will not check the user identity provided and therefore will not provide a user identity response at all.

LOGGING

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.

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 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).

ENVIRONMENT

The storescu 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.
