Content
Following fields of an archive attribute coercion rule determine whether a particular rule will get applied or not. To coerce outgoing (MWL) C-FIND responses, fields should be configured as
Rule Priority : For each shown DIMSE transaction, if multiple coercion rules with exact values for specified fields are configured, higher rule priority coercion rule takes precedence
| Coercion Rule field | Value / Notes |
|---|---|
| Conditions | May be configured according to requirement, to limit the rule only to certain conditions. eg. SendingApplicationEntityTitle=MOD_US01 or Modality=CR|CT (specifying multiple values separated by |) or Modality!=CR|CT (specifying multiple values separated by | with not equals condition) |
Outgoing (MWL) C-FIND responses sent from archive can be coerced using one or more coercion features available in a coercion rule as shown below.
- eg. If corresponding shown fields are configured, coercing by XSL stylesheet is applied at last.
Note : Each coercion type gets applied only if corresponding fields are configured. Examples shown for some fields.

| Merge Attributes | Used for merging values of one or more DICOM tags in outgoing (MWL) C-FIND response using different Attribute Formats or by specifying static values in combination with attributes values. - eg. PatientID={PatientID,slice,3} or by specifying static values in combination with received values. - eg. AdmissionID=ADM-{AdmissionID} |
