storescu(1) OFFIS DCMTK storescu(1) # [NAME](#NAME) storescu - DICOM storage (C-STORE) SCU # [SYNOPSIS](#SYNOPSIS) ``` storescu [options] peer port dcmfile-in... ``` # [DESCRIPTION](#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. # [PARAMETERS](#PARAMETERS) ``` peer hostname of DICOM peer port tcp/ip port number of peer dcmfile-in DICOM file or directory to be transmitted ``` # [OPTIONS](#OPTIONS) ##

[Scanning Directories](#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. ## [DICOM Conformance](#DICOM_Conformance) The **storescu** application supports the following Storage SOP Classes as an SCU: ``` ComputedRadiographyImageStorage 1.2.840.10008.5.1.4.1.1.1 DigitalXRayImageStorageForPresentation 1.2.840.10008.5.1.4.1.1.1.1 DigitalXRayImageStorageForProcessing 1.2.840.10008.5.1.4.1.1.1.1.1 DigitalMammographyXRayImageStorageForPresentation 1.2.840.10008.5.1.4.1.1.1.2 DigitalMammographyXRayImageStorageForProcessing 1.2.840.10008.5.1.4.1.1.1.2.1 DigitalIntraOralXRayImageStorageForPresentation 1.2.840.10008.5.1.4.1.1.1.3 DigitalIntraOralXRayImageStorageForProcessing 1.2.840.10008.5.1.4.1.1.1.3.1 CTImageStorage 1.2.840.10008.5.1.4.1.1.2 EnhancedCTImageStorage 1.2.840.10008.5.1.4.1.1.2.1 UltrasoundMultiframeImageStorage 1.2.840.10008.5.1.4.1.1.3.1 MRImageStorage 1.2.840.10008.5.1.4.1.1.4 EnhancedMRImageStorage 1.2.840.10008.5.1.4.1.1.4.1 MRSpectroscopyStorage 1.2.840.10008.5.1.4.1.1.4.2 UltrasoundImageStorage 1.2.840.10008.5.1.4.1.1.6.1 SecondaryCaptureImageStorage 1.2.840.10008.5.1.4.1.1.7 MultiframeSingleBitSecondaryCaptureImageStorage 1.2.840.10008.5.1.4.1.1.7.1 MultiframeGrayscaleByteSecondaryCaptureImageStorage 1.2.840.10008.5.1.4.1.1.7.2 MultiframeGrayscaleWordSecondaryCaptureImageStorage 1.2.840.10008.5.1.4.1.1.7.3 MultiframeTrueColorSecondaryCaptureImageStorage 1.2.840.10008.5.1.4.1.1.7.4 TwelveLeadECGWaveformStorage 1.2.840.10008.5.1.4.1.1.9.1.1 GeneralECGWaveformStorage 1.2.840.10008.5.1.4.1.1.9.1.2 AmbulatoryECGWaveformStorage 1.2.840.10008.5.1.4.1.1.9.1.3 HemodynamicWaveformStorage 1.2.840.10008.5.1.4.1.1.9.2.1 CardiacElectrophysiologyWaveformStorage 1.2.840.10008.5.1.4.1.1.9.3.1 BasicVoiceAudioWaveformStorage 1.2.840.10008.5.1.4.1.1.9.4.1 GrayscaleSoftcopyPresentationStateStorage 1.2.840.10008.5.1.4.1.1.11.1 ColorSoftcopyPresentationStateStorage 1.2.840.10008.5.1.4.1.1.11.2 PseudoColorSoftcopyPresentationStateStorage 1.2.840.10008.5.1.4.1.1.11.3 BlendingSoftcopyPresentationStateStorage 1.2.840.10008.5.1.4.1.1.11.4 XRayAngiographicImageStorage 1.2.840.10008.5.1.4.1.1.12.1 EnhancedXAImageStorage 1.2.840.10008.5.1.4.1.1.12.1.1 XRayRadiofluoroscopicImageStorage 1.2.840.10008.5.1.4.1.1.12.2 EnhancedXRFImageStorage 1.2.840.10008.5.1.4.1.1.12.2.1 NuclearMedicineImageStorage 1.2.840.10008.5.1.4.1.1.20 RawDataStorage 1.2.840.10008.5.1.4.1.1.66 SpatialRegistrationStorage 1.2.840.10008.5.1.4.1.1.66.1 SpatialFiducialsStorage 1.2.840.10008.5.1.4.1.1.66.2 RealWorldValueMappingStorage 1.2.840.10008.5.1.4.1.1.67 VLEndoscopicImageStorage 1.2.840.10008.5.1.4.1.1.77.1.1 VLMicroscopicImageStorage 1.2.840.10008.5.1.4.1.1.77.1.2 VLSlideCoordinatesMicroscopicImageStorage 1.2.840.10008.5.1.4.1.1.77.1.3 VLPhotographicImageStorage 1.2.840.10008.5.1.4.1.1.77.1.4 OphthalmicPhotography8BitImageStorage 1.2.840.10008.5.1.4.1.1.77.1.5.1 OphthalmicPhotography16BitImageStorage 1.2.840.10008.5.1.4.1.1.77.1.5.2 StereometricRelationshipStorage 1.2.840.10008.5.1.4.1.1.77.1.5.3 OphthalmicTomographyImageStorage 1.2.840.10008.5.1.4.1.1.77.1.5.4 BasicTextSRStorage 1.2.840.10008.5.1.4.1.1.88.11 EnhancedSRStorage 1.2.840.10008.5.1.4.1.1.88.22 ComprehensiveSRStorage 1.2.840.10008.5.1.4.1.1.88.33 ProcedureLogStorage 1.2.840.10008.5.1.4.1.1.88.40 MammographyCADSRStorage 1.2.840.10008.5.1.4.1.1.88.50 KeyObjectSelectionDocumentStorage 1.2.840.10008.5.1.4.1.1.88.59 ChestCADSRStorage 1.2.840.10008.5.1.4.1.1.88.65 XRayRadiationDoseSRStorage 1.2.840.10008.5.1.4.1.1.88.67 ColonCADSRStorage 1.2.840.10008.5.1.4.1.1.88.69 EncapsulatedPDFStorage 1.2.840.10008.5.1.4.1.1.104.1 PositronEmissionTomographyImageStorage 1.2.840.10008.5.1.4.1.1.128 RTImageStorage 1.2.840.10008.5.1.4.1.1.481.1 RTDoseStorage 1.2.840.10008.5.1.4.1.1.481.2 RTStructureSetStorage 1.2.840.10008.5.1.4.1.1.481.3 RTBeamsTreatmentRecordStorage 1.2.840.10008.5.1.4.1.1.481.4 RTPlanStorage 1.2.840.10008.5.1.4.1.1.481.5 RTBrachyTreatmentRecordStorage 1.2.840.10008.5.1.4.1.1.481.6 RTTreatmentSummaryRecordStorage 1.2.840.10008.5.1.4.1.1.481.7 ``` 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: ``` LittleEndianImplicitTransferSyntax 1.2.840.10008.1.2 LittleEndianExplicitTransferSyntax 1.2.840.10008.1.2.1 DeflatedExplicitVRLittleEndianTransferSyntax 1.2.840.10008.1.2.1.99 (*) BigEndianExplicitTransferSyntax 1.2.840.10008.1.2.2 JPEGProcess1TransferSyntax 1.2.840.10008.1.2.4.50 JPEGProcess2_4TransferSyntax 1.2.840.10008.1.2.4.51 JPEGProcess14SV1TransferSyntax 1.2.840.10008.1.2.4.70 JPEGLSLosslessTransferSyntax 1.2.840.10008.1.2.4.80 JPEGLSLossyTransferSyntax 1.2.840.10008.1.2.4.81 JPEG2000LosslessOnlyTransferSyntax 1.2.840.10008.1.2.4.90 JPEG2000TransferSyntax 1.2.840.10008.1.2.4.91 MPEG2MainProfileAtMainLevelTransferSyntax 1.2.840.10008.1.2.4.100 MPEG2MainProfileAtHighLevelTransferSyntax 1.2.840.10008.1.2.4.101 MPEG4HighProfileLevel4_1TransferSyntax 1.2.840.10008.1.2.4.102 MPEG4BDcompatibleHighProfileLevel4_1TransferSyntax 1.2.840.10008.1.2.4.103 MPEG4HighProfileLevel4_2_For2DVideoTransferSyntax 1.2.840.10008.1.2.4.104 MPEG4HighProfileLevel4_2_For3DVideoTransferSyntax 1.2.840.10008.1.2.4.105 MPEG4StereoHighProfileLevel4_2TransferSyntax 1.2.840.10008.1.2.4.106 HEVCMainProfileLevel5_1TransferSyntax 1.2.840.10008.1.2.4.107 HEVCMain10ProfileLevel5_1TransferSyntax 1.2.840.10008.1.2.4.108 RLELosslessTransferSyntax 1.2.840.10008.1.2.5 ``` (\*) if compiled with zlib support enabled (see *--version* output) 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](#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](#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](#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](#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](#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. # [FILES](#FILES) *<docdir>/asconfig.txt* - configuration file documentation *<etcdir>/storescu.cfg* - example association negotiation profile # [SEE ALSO](#SEE_ALSO) [**storescp**(1)](/man/os/dcmtk/storescp.1) # [COPYRIGHT](#COPYRIGHT) Copyright (C) 1996-2025 by OFFIS e.V., Escherweg 2, 26121 Oldenburg, Germany.
