selects a range type from the “Exam date” pull down menu, where the choices are
All, Before, Between, or Exactly. Once a range type is selected, the correct
number of fields appear and the operator enters dates into those fields.
Once the desired parameters are entered the operator chooses “OK” and that will
cause the DICOM Server AE to initiate an association to the selected Remote AE.
Once a list of Study/Series/Image is retrieved, the operator can invoke the “Pull”
operation by choosing “Get Exam” or “Get Series” or “Get Image” from the
“Network” pull-down menu, or the operator can cause a new association with
different parameters to the same Remote AE by choosing “Change search
parameters” from the “Search” pull-down menu on the remote database manager.
2.2.1.2.2.2 Proposed Presentation Contexts
When the Real-World activity “Query” or “Pull” is initiated all presentation contexts
shown in table 2.2.1.2.1.2-1 are proposed during association establishment, but
only the Query/Retrieve-FIND related contexts are applicable to this activity.
2.2.1.2.2.2.1 SOP Specific Conformance Statement for C-FIND SCU
After the Query operation is initiated, the DICOM Server AE will perform a study-
root C-FIND-RQ request at each of the three levels (Study, Series, and Image) in
succession.
The Initial Study-Level request will ask for all studies in the Remote database that
match the user specified Patient name, Patient id, Study date, Accession number,
and Study id. Zero length data in any of those fields means match on any value.
Zero length data is the default value if the user does not specify a value. The user
specified Patient name will come surrounded by single asterisks (asterisk is a wild
card that matched any number of characters). The Study date is a range of dates
where a date is exactly 8 characters long and the format of the range is:
“” is any date,
“yyyymmdd-“ is any date on or before that year/month/day,
“yyyymmdd-yyyymmdd” is any date on or between those dates,
“yyyymmdd” is only on that date.
The C-FIND SCU will not perform any extended negotiation and so will only
perform hierarchical query.
Each C-FIND SCU operation supports an “Association Timer”, “Operation
Inactivity Timer” and “Session Timer” with time out values of 900 seconds, 900
seconds and 60 minutes respectively. These values are configurable in dcs.cfg.
If a “Cancel” or “Refused” status is returned from the Remote AE the association is
closed and the operation terminated.
The DICOM Server AE will parse each matching C-FIND-RSP reply and ignore the
entries that do not contain a valid DICOM data stream. No VR validation is
performed which means that syntax errors will be ignored.
Tables 2.2.1.2.2.2.1-1 - 2.2.1.2.2.2.1-3 shows the various fields that are requested
at the Study, Series, and Image levels of the C-FIND request.
