NAME
storescp - DICOM storage (C-STORE) SCP
SYNOPSIS
storescp [options] [port]
DESCRIPTION
The storescp application implements a Service Class Provider (SCP) for the Storage Service
Class. It listens on a specific TCP/IP port for incoming association requests from a
Storage Service Class User (SCU) and can receive both DICOM images and other DICOM
composite objects. The storescp application also supports the Verification Service Class
as an SCP.

NOTES
The semantic impacts of the above mentioned options is clear for the majority of options.
Some particular options, however, are so specific that they need detailed descriptions
which will be given in this passage.
Option --sort-conc-studies enables a user to sort all received DICOM objects into
different subdirectories. The sorting will be done with regard to the studies the
individual objects belong to, i.e. objects that belong to the same study will be stored in
the same subdirectory. In general, a DICOM object d_n+1 is considered to belong to the
same study as a DICOM object d_n if and only if d_n and d_n+1 show the exact same values
in attribute Study Instance UID. The names of the resulting subdirectories always start
with a prefix p which was passed to this option as a parameter. In addition to this
prefix, the subdirectory names contain time stamp information with regard to the date and
time of reception of this particular study's first DICOM object. In detail, the
determination of the subdirectory names pertains to the pattern
[prefix]_[YYYYMMDD]_[HHMMSSPPP]
where YYYY refers to year (4 digits), MM to month (01-12), DD to day (01-31), HH to hour
(00-23), MM to minute (00-59), SS to second (00-59) and PPP to milliseconds (000-999). If
the prefix is an empty string, the first '_' is omitted.
The other --sort-xxx options work in a similar manner, only the subdirectory names are
created differently. For option --sort-on-study-uid the pattern is
[prefix]_[StudyInstanceUID]
and for option --sort-on-patientname
[PatientName]_[YYYYMMDD]_[HHMMSSPPP]
where 'PatientName' is replaced by 'ANONYMOUS' if the data element is empty or absent in
the data set. Please note, however, that for option --sort-on-study-uid the same
subdirectory will be used for all DICOM objects that belong to the same study, i.e. in
contrast to the other --sort-xxx options there is no guarantee that a study directory is
ever completed.
Option --timenames creates filenames from timestamps corresponding to the time, storescp
writes a file to disk. The format is
[YYYYMMDDHHMMSSPPP]_[SERIALNO].[MD]
where YYYY, MM, DD, HH, MM, SS, PPP are interpreted as described above. If more files are
created at the same time, SERIALNO is inserted. It consists of a 4-digit, consecutive
number (0000 to 9999). For the first file, that exists for a specific time, no number (and
no '_') is inserted at all. MD represents an identification code (2 letters) for the kind
of object stored in the file (see notes on --rename-on-eostudy).
Option --filename-extension appends a specified suffix to each filename (a dot '.' is not
added automatically). This suffix is not appended to the filenames created by --rename-on-
eostudy to maintain the length of 8 characters.
Option --exec-on-reception allows to execute a certain command line after having received
and processed one DICOM object (through a C-STORE-RQ message). The command line to be
executed is passed to this option as a parameter. The specified command line may contain a
number of placeholders which will be replaced at run time:
• #p: complete path to the output directory into which the last DICOM object was stored
(not available with option --ignore though)
• #f: filename of the current output file (not available with option --ignore though)
• #a: calling application entity title of the peer Storage SCU
• #c: called application entity title used by the peer Storage SCU to address storescp
• #r: calling presentation address, i.e. hostname or IP address of the peer Storage SCU
The specified command line is executed as a separate process, so that the execution of
storescp will not be held back.
Option --exec-on-eostudy allows to execute a certain command line when all DICOM objects
that belong to one study have been received by storescp. The same placeholders as with
--exec-on-reception may be used, except for '#f', which is not supported. A study is
considered complete by storescp when an object belonging to a different study is received
or the timeout specified with --eostudy-timeout takes place. If option --rename-on-eostudy
is in force, the renaming takes place before the external command is executed.
Option --rename-on-eostudy refers to the above mentioned --sort-xxx options and can only
be used in combination with one of these options. If a user specifies option --rename-on-
eostudy and storescp determines that all DICOM objects that belong to a certain study have
been received, all DICOM files that belong to the last study will be renamed in the
corresponding output directory. The filenames into which the files are being renamed will
be calculated using the pattern
[prefix][consecutive numbering]
where [prefix] is a 2 character prefix that reveals the kind of DICOM object stored in the
file and [consecutive numbering] is a consecutively numbered, 6-digit number, starting at
'000001'. In general, the question if all DICOM objects that belong to one study have been
received by storescp will be answered positively if and only if two consecutively received
DICOM objects d_n and d_n+1 do not show the same values in attribute Study Instance UID;
in such a case, d_n+1 is considered to belong to a new study.
Using option --eostudy-timeout a user can modify the determination process to figure out
if all DICOM objects that belong to one study have already been received by storescp. With
regard to this fact, it is clear that this option can only be used in combination with at
least one of the following options: --sort-xxx, --exec-on-eostudy and --rename-on-eostudy.
If option --eostudy-timeout is specified, the end of a study is considered to have
occurred not only if two consecutively received DICOM objects d_n and d_n+1 do not show
the same values in attribute Study Instance UID, but also if whithin a time span of x
seconds after the reception of a DICOM object d_n, no other DICOM object was received over
the network. Note that the amount x of seconds (which determines the length of this time
span) has to be passed to this option as a parameter.

The storescp application will 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
The default behaviour of the storescp application is to prefer transfer syntaxes having an
explicit encoding over the default implicit transfer syntax. If storescp is running on
big-endian hardware it will prefer BigEndianExplicit to LittleEndianExplicit transfer
syntax (and vice versa). This behaviour 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

Additional Storage SOP Classes and Transfer Syntaxes can be used with the so-called
'association negotiation profiles' (see below).
The storescp 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.
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 storescp 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).
Running storescp from inetd
On Posix platforms, storescp can be initiated through the inetd(8) super server. This
requires that storescp be configured in the /etc/inetd.conf configuration file. A typical
configuration line could look like this:
acr-nema stream tcp nowait root /usr/sbin/storescp -id +ac -od /tmp/storescp
where -id (--inetd) activates the inetd mode in which the DICOM association is actually
accepted by inetd and passed to storescp, +ac (--access-control) activates the TCP wrapper
based access control described above and -od (--output-directory) defines the directory in
which storescp stores incoming DICOM objects. Note that the service name ('acr-nema' in
this example) determines the port number on which DICOM associations are accepted and must
be defined in /etc/services. When runnning from inetd, the stdout and stderr streams are
redirected to files in the /tmp filesystem which can be identified by the filename
starting with the prefix 'storescp_'.
Please note that when run through inetd, storescp is executed with root privileges, which
may be a security risk.
Association Negotiation Profiles and Configuration Files
storescp supports a flexible mechanism for specifying the DICOM network association
negotiation behaviour, 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.
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 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 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 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 storescp 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 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. 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.
