Each C-STORE operation also supports a “Session Timer”. This timer starts when the

association is established and stops when the association is ended. This time-out is 60 minutes.

If any of the three timers mentioned above expires, the connection is closed and the operation

in progress is considered failed.

Note: The time-outs are configurable.

When DICOM Server AE initiates an association to issue a C-STORE, the following will occur:

1. The image will be transmitted by the DICOM Server AE with the same elements as was

originally received or created locally (for the standard elements only).

2.3.1.2.2 Query Remote AE

2.3.1.2.2.1 Associated Real-World Activity

The operator must first select a destination by choosing “Select Remote Host” from “Network”

pull-down menu on the local database manager and then choose a hostname. To do custom

queries select “Yes” for “Custom search” option.

Note: Custom queries can be done on the following fields “Last Name contains”, “Exam

Number”, “Patient Id”, “Accession Number”.

To initiate a Query select “Receive” from “Network” pull-down menu.

Note: If “Custom Search” option is set then a small GUI will show up. Operator will be

able to enter custom query fields. Entering values in ”Last Name contains” field

will initiate wild card query for patient name.

The “Query” operation will cause the DICOM Server AE to initiate an association to the selected

Remote AE when the “Query Remote Host” entry is selected from the “Network” pull-down

menu. Once a list of Study/Series/Image is retrieved, the operator can invoke the “Get”

operation by choosing “Get Exam” or “Get Series” or “Get Image” from the “Network” pull-down

menu.

2.3.1.2.2.2 Proposed Presentation Contexts

When the Real-World activity “Query” or “Get” 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.

2.3.1.2.2.2.1 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.

The C-FIND SCU will not perform any extended negotiation and so will only perform

hierarchical query. Relational Queries are not supported. C-CANCEL-FIND-RQ is not

supported.
