       findscu - DICOM query (C-FIND) SCU


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


       The  findscu  application  implements  an SCU for the Query/Retrieve Service Class and the
       Basic Worklist Management Service Class. findscu only supports query  functionality  using
       the  C-FIND  message.  It sends query keys to an SCP and awaits responses. The application
       can be used to test SCPs of the  Query/Retrieve  and  Basic  Worklist  Management  Service

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

       # query patient names and IDs
       (0008,0052) CS [PATIENT]     # QueryRetrieveLevel
       (0010,0010) PN []            # PatientName
       (0010,0020) LO []            # PatientID

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

       findscu -P -k "(0010,0010)=HEWETT*" caesar 5678 patqry.dcm

       will,  when sent to the SCP caesar at TCP/IP port 5678, cause any PatientName attribute in
       patqry.dcm to have the value 'HEWETT*'. 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

       In  earlier  versions  of findscu, the tag keys were specified without braces around group
       and element number,  e.  g.  '0010,0010'  instead  of  '(0010,0010)'.  It  is  recommended
       switching to the new syntax; however, the old syntax is still working.

       Also  -k  accepts  dictionary names instead of element tags for specifying DICOM elements.
       For example, the findscu call above then reads like this:

       findscu -P -k PatientName="HEWETT*" caesar 5678 patqry.dcm

       It is also possible to specify sequences, items and nested attributes using the -k option.
       In these cases, a special 'path' notation has to be used, e. g.

       findscu -W -k "(0040,0100)[0].Modality=CT" caesar 5678

       This  call  queries  a  worklist  server  at host caesar for any planned procedures for CT
       modalities by specifing  tag  (0040,0100)  'Scheduled  Procedure  Step  Sequence'  and  an
       attribute  'Modality'  in the first item of this sequence with value 'CT'. Details on this
       path notation can be found in the documentation of dcmodify.

       If no file is specified on the command line, the query must be specified  completely  with
       one or more -k options.

       Each  set  of  response  identifiers  received  will  be  printed  to stdout unless option
       --extract is used.

   DICOM Conformance
       The findscu application supports the following SOP Classes as an SCU:

       FINDPatientRootQueryRetrieveInformationModel       1.2.840.10008.
       FINDStudyRootQueryRetrieveInformationModel         1.2.840.10008.
       FINDPatientStudyOnlyQueryRetrieveInformationModel  1.2.840.10008.
       FINDModalityWorklistInformationModel               1.2.840.10008.

       The findscu application will propose presentation contexts for one of  the  abovementioned
       supported  SOP Classes depending on command line options (-P, -S, -O or -W). Each proposed
       presentation context will propose 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

       The findscu application does not support extended negotiation.


       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 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).


       The findscu 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.
