NAME

6       findscu - DICOM query (C-FIND) SCU
7

SYNOPSIS

9       findscu [options] peer port [dcmfile-in...]
10

DESCRIPTION

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

NOTES

202       Each file supplied on the command line will be sent to the SCP as  part
203       of  a  C-FIND  request.  The  query file must be a valid DICOM data set
204       containing the dataset part of a  C-FIND-RQ  message.  The  query  file
205       could, for instance, be created with the dump2dcm utility from a script
206       like the following example:
207
208       # query patient names and IDs
209       (0008,0052) CS [PATIENT]     # QueryRetrieveLevel
210       (0010,0010) PN []            # PatientName
211       (0010,0020) LO []            # PatientID
212
213       Individual attributes of each file sent can be modified or supplemented
214       using the -k option. For example the command:
215
216       findscu -P -k "(0010,0010)=HEWETT*" caesar 5678 patqry.dcm
217
218       will,  when  sent  to  the  SCP  caesar  at TCP/IP port 5678, cause any
219       PatientName attribute in patqry.dcm to have  the  value  'HEWETT*'.  If
220       such  an attribute is present it will be replaced, if absent it will be
221       inserted. The -k option can be present more than once. The  value  part
222       (after  the  '=')  may  be absent causing the attribute to be sent with
223       zero length.
224
225       In earlier versions of findscu, the tag  keys  were  specified  without
226       braces  around  group  and element number, e. g. '0010,0010' instead of
227       '(0010,0010)'. It is recommended switching to the new syntax;  however,
228       the old syntax is still working.
229
230       Also -k accepts dictionary names instead of element tags for specifying
231       DICOM elements. For example, the findscu call  above  then  reads  like
232       this:
233
234       findscu -P -k PatientName="HEWETT*" caesar 5678 patqry.dcm
235
236       It  is  also possible to specify sequences, items and nested attributes
237       using the -k option. In these cases, a special 'path' notation  has  to
238       be used, e. g.
239
240       findscu -W -k "(0040,0100)[0].Modality=CT" caesar 5678
241
242       This  call  queries  a  worklist  server at host caesar for any planned
243       procedures for CT modalities by specifing  tag  (0040,0100)  'Scheduled
244       Procedure  Step Sequence' and an attribute 'Modality' in the first item
245       of this sequence with value 'CT'. Details on this path notation can  be
246       found in the documentation of dcmodify.
247
248       If  no  file  is  specified  on  the  command  line,  the query must be
249       specified completely with one or more -k options.
250
251       Each set of response identifiers received will  be  printed  to  stdout
252       unless option --extract is used.
253
254   DICOM Conformance
255       The findscu application supports the following SOP Classes as an SCU:
256
257       FINDPatientRootQueryRetrieveInformationModel       1.2.840.10008.5.1.4.1.2.1.1
258       FINDStudyRootQueryRetrieveInformationModel         1.2.840.10008.5.1.4.1.2.2.1
259       FINDPatientStudyOnlyQueryRetrieveInformationModel  1.2.840.10008.5.1.4.1.2.3.1
260       FINDModalityWorklistInformationModel               1.2.840.10008.5.1.4.31
261
262       The  findscu  application will propose presentation contexts for one of
263       the abovementioned supported SOP  Classes  depending  on  command  line
264       options  (-P,  -S,  -O  or -W). Each proposed presentation context will
265       propose the transfer syntaxes:
266
267       LittleEndianImplicitTransferSyntax                 1.2.840.10008.1.2
268       LittleEndianExplicitTransferSyntax                 1.2.840.10008.1.2.1
269       BigEndianExplicitTransferSyntax                    1.2.840.10008.1.2.2
270
271       The findscu application does not support extended negotiation.
272

LOGGING

274       The level of logging output of  the  various  command  line  tools  and
275       underlying  libraries  can  be  specified by the user. By default, only
276       errors and warnings are written to the  standard  error  stream.  Using
277       option  --verbose  also  informational messages like processing details
278       are reported. Option --debug can be used to get  more  details  on  the
279       internal  activity,  e.g.  for debugging purposes. Other logging levels
280       can be selected using option --log-level. In --quiet  mode  only  fatal
281       errors  are reported. In such very severe error events, the application
282       will usually terminate. For  more  details  on  the  different  logging
283       levels, see documentation of module 'oflog'.
284
285       In  case  the logging output should be written to file (optionally with
286       logfile rotation), to syslog (Unix) or the event log  (Windows)  option
287       --log-config  can  be  used.  This  configuration  file also allows for
288       directing only certain messages to a particular output stream  and  for
289       filtering  certain  messages  based  on the module or application where
290       they are generated.  An  example  configuration  file  is  provided  in
291       <etcdir>/logger.cfg).
292

COMMAND LINE

294       All  command  line  tools  use  the  following notation for parameters:
295       square brackets enclose optional  values  (0-1),  three  trailing  dots
296       indicate  that multiple values are allowed (1-n), a combination of both
297       means 0 to n values.
298
299       Command line options are distinguished from parameters by a leading '+'
300       or  '-' sign, respectively. Usually, order and position of command line
301       options are arbitrary (i.e. they  can  appear  anywhere).  However,  if
302       options  are  mutually exclusive the rightmost appearance is used. This
303       behaviour conforms to the standard  evaluation  rules  of  common  Unix
304       shells.
305
306       In  addition,  one  or more command files can be specified using an '@'
307       sign as a prefix to the filename (e.g. @command.txt).  Such  a  command
308       argument  is  replaced  by  the  content of the corresponding text file
309       (multiple whitespaces are treated as a  single  separator  unless  they
310       appear  between  two  quotation marks) prior to any further evaluation.
311       Please note that a command file cannot contain  another  command  file.
312       This   simple   but  effective  approach  allows  to  summarize  common
313       combinations of options/parameters and  avoids  longish  and  confusing
314       command lines (an example is provided in file <datadir>/dumppat.txt).
315

ENVIRONMENT

317       The  findscu  utility  will  attempt  to  load  DICOM data dictionaries
318       specified in the DCMDICTPATH environment variable. By default, i.e.  if
319       the   DCMDICTPATH   environment   variable   is   not   set,  the  file
320       <datadir>/dicom.dic will be loaded unless the dictionary is built  into
321       the application (default for Windows).
322
323       The   default   behaviour  should  be  preferred  and  the  DCMDICTPATH
324       environment variable only used when alternative data  dictionaries  are
325       required.  The  DCMDICTPATH environment variable has the same format as
326       the Unix shell PATH variable in that a colon (':')  separates  entries.
327       On  Windows systems, a semicolon (';') is used as a separator. The data
328       dictionary code will  attempt  to  load  each  file  specified  in  the
329       DCMDICTPATH  environment variable. It is an error if no data dictionary
330       can be loaded.
